1972 Jimmy + 5.3/4L60E/NP205
2 Attachment(s)
Well I guess the time is now. The plan is to do a 5.3/4L60E and mate the stock t-case to it. I have an 04 pullout with only 55k that a buddy of mine ran into recently. Ran a carfax on the truck it came out of and all seems legitimate. Picking up the engine, tranny, harness, ECM this week.
Started an early morning tear down last weekend with my lil bro... Cheers and most importantly thanks for all the info gathered here and ls1nova71 for already answering numerous questions that I have thrown his way!! |
Re: 1972 Jimmy + 5.3/4L60E/NP205
In for this, would love to do same to mine. Nice rig!

Re: 1972 Jimmy + 5.3/4L60E/NP205
Excited to see this one. If you take that many pics of just the tear down would like to see how many we get with the actual detail of the build. ha Keep them coming..

Re: 1972 Jimmy + 5.3/4L60E/NP205
Well, I guess there's no going back now! I'll be watching, and if there's anything I can do to help, just ask.

Re: 1972 Jimmy + 5.3/4L60E/NP205
Few things trickling in over the last week...
Ordered the DD gauges with the ECM interface. Ordered the PacFab crossmember Ordered the AA kit with all the parts. - FYI - I ordered this from Summit Racing and it was about $100 cheaper than AA. Plus free shipping. It was all in stock and was here in 2 days. http://i12.photobucket.com/albums/a2...psxbgxxjqy.jpg http://i12.photobucket.com/albums/a2...psg0qh1rhj.jpg http://i12.photobucket.com/albums/a2...psngrpa28q.jpg http://i12.photobucket.com/albums/a2...ps6fdgze3v.jpg http://i12.photobucket.com/albums/a2...psfmck0nvv.jpg |
Re: 1972 Jimmy + 5.3/4L60E/NP205
Are you ever going to update this build theead? I know youve got some things done....... :metal:
|
Re: 1972 Jimmy + 5.3/4L60E/NP205
Yeah, I'm curious too !! I just received my adapter kit, and I'm really liking that Dakota dash cluster. Looks like one of those is in my future too.

Re: 1972 Jimmy + 5.3/4L60E/NP205
alright alright... little bit of an update.
First - my original frame had been in a wreck, hacked up, and a new front end welded back on very poorly.. Both frame rails had been cut just under the firewall. The "donor" front end they found was from a 71 truck. The truck had always driven straight, but this just looked like an accident waiting to happen. So I got a SWEET deal on another 72 frame from board member larryd. I pulled the old frame out and the new frame got blasted and powder coated. http://i12.photobucket.com/albums/a2...psaiwit8lj.jpg http://i12.photobucket.com/albums/a2...pst4zfclvl.jpg http://i12.photobucket.com/albums/a2...pseu8wnjti.jpg http://i12.photobucket.com/albums/a2...psqlkrxml7.jpg I won't be running AC so I pulled all this off and got a AC delete cover that I will be using in it's place. http://i12.photobucket.com/albums/a2...pscjfzn2bh.jpg http://i12.photobucket.com/albums/a2...psecsemmlj.jpg http://i12.photobucket.com/albums/a2...psbwi3dbl2.jpg http://i12.photobucket.com/albums/a2...psglzdkkyy.jpg Then the frame removal.... http://i12.photobucket.com/albums/a2...ps5rnxjtmb.jpg http://i12.photobucket.com/albums/a2...psbq3lae01.jpg http://i12.photobucket.com/albums/a2...psvkjwa2o8.jpg http://i12.photobucket.com/albums/a2...psybdmljdk.jpg http://i12.photobucket.com/albums/a2...psye9ysjgq.jpg http://i12.photobucket.com/albums/a2...psn58ebkmn.jpg http://i12.photobucket.com/albums/a2...psnz84twem.jpg http://i12.photobucket.com/albums/a2...pswoljwzax.jpg http://i12.photobucket.com/albums/a2...pshhj9t2vl.jpg http://i12.photobucket.com/albums/a2...psz9t1nnyj.jpg http://i12.photobucket.com/albums/a2...pslxypuyiq.jpg http://i12.photobucket.com/albums/a2...psslwltarq.jpg Then the new frame got back from the coater. Turned out awesome. I purchased new 2.5 lift springs front and rear from Skyjacker at this time as well. Got everything loosely bolted up and she at least rolls right now. Also installed a 87 blazer tank (31 gallon) and the sending unit to match. I'm going to run a walbro 255 in tank in place of the factory 87 pump since it is not high pressure. http://i12.photobucket.com/albums/a2...psufrzjlei.jpg http://i12.photobucket.com/albums/a2...ps59yvjmci.jpg http://i12.photobucket.com/albums/a2...psuek3wnts.jpg http://i12.photobucket.com/albums/a2...ps6kkjfyar.jpg http://i12.photobucket.com/albums/a2...psjoa8i7zw.jpg http://i12.photobucket.com/albums/a2...psfhwjnw6f.jpg http://i12.photobucket.com/albums/a2...ps4nnijf8k.jpg http://i12.photobucket.com/albums/a2...psai2hgwnw.jpg |
Re: 1972 Jimmy + 5.3/4L60E/NP205
I went to go have the local tranny shop swap out my AA output shaft and come to find out it was toast (the tranny) despite only having 55k miles on it. I called the lot I got it from and they told me that the t-case from the donor truck was cracked when they got the truck and someone must have driven it while all the fluid was leaking out and burned it up. Long story short, they are crediting me and I had another one I already had, rebuilt with some upgraded parts and shift kit. So now everything is brand new and no worries there anymore.
I installed the t-case with new poly bushings and the x-member. And then hooked up the rest of the AA kit to the back of the tranny (VSS, clocking ring, etc) It was time to do a mock up in order to find out where my PacFab engine crossmember needed to be installed so I did that today. Got it all installed. Went pretty well. The bump stop brackets needed to be removed as the X-member was right on top of the factory rivets. http://i12.photobucket.com/albums/a2...psabtwwjcw.jpg http://i12.photobucket.com/albums/a2...pskidzyrpw.jpg http://i12.photobucket.com/albums/a2...psn9af0skw.jpg http://i12.photobucket.com/albums/a2...psfawicthu.jpg http://i12.photobucket.com/albums/a2...psk79q0j1m.jpg http://i12.photobucket.com/albums/a2...psj7mlwc1b.jpg http://i12.photobucket.com/albums/a2...pseyx9fynx.jpg http://i12.photobucket.com/albums/a2...psrpozlnaa.jpg http://i12.photobucket.com/albums/a2...psitarbmka.jpg http://i12.photobucket.com/albums/a2...ps2rzchwn5.jpg http://i12.photobucket.com/albums/a2...psskcp6nkv.jpg Next I am going to plumb all my fuel, transmission, brake lines while the drivetrain is on the frame. If I was smart I would have backed my truck into the garage for the tear down, I can't get the frame back under it with the engine/tranny installed so I'll pull those when the time comes and put the body back on. |
Re: 1972 Jimmy + 5.3/4L60E/NP205
Looking good !! You mentioned that you had the frame powder coated, but what did you use to paint the diff housings? I've been trying to find a 2-part semi gloss black and ended up buying some Eastwood product.
Also, how much more forward does the 5.3 end up as compared to the original engine? I've been gathering parts for the past couple months and will be doing almost the exact build that you're doing. Dan |
Re: 1972 Jimmy + 5.3/4L60E/NP205
I just used the "semi-gloss" black in the Dupli-color Engine Enamel.
I had the axles blasted down to bare metal, so I hit them with some self-etching primer first. I don't have the exact measurements but I would guess that it moved the engine forward around 2" or less. If you want, measure from your crank pulley on yours to the front crossmember and I'll do the same. |
Re: 1972 Jimmy + 5.3/4L60E/NP205
I just checked the location of the original engine, and the front of the pulley is 11 1/4" from the rad support. I would estimate that the pulley is about 2 1/4 inches away from the rear lower part of the cross member. Regardless, there's tons of room.
I'm still debating whether I'll be running AC. Do you think there's enough clearance for the l 5.3 compressor in it's original location? I just cleaned the block on my 5.3, and looks just as clean as yours under the rocker cover. The block itself though was coated with a layer of rust about 1/16 thick thanks to our Canadian winters and road salt. Another question I had is which power steering pump will you be using? I'd like to use the one on the 5.3, but concerned about differences in pressure. BTW, my truck is originally from Salem Missouri. |
Re: 1972 Jimmy + 5.3/4L60E/NP205
My crank pulley to the front crossmember is right at 1 1/4"
I slapped on my AC compressor and took some pictures. I don't think it is going to happen without notching the frame. A custom fitting wouldn't be an option either, at least from the angles I am looking at. A different mount would be the best way to do this. As far as the power steering I am planning on using the factory 5.3 pump with a hydroboost out of the same year 04-2500. I have heard you can use a fitting on the rear of the pump to reduce the flow of the fluid. I'll post the picture and part # if I find it. http://i12.photobucket.com/albums/a2...ps4idvwkfk.jpg http://i12.photobucket.com/albums/a2...ps2a3xvqvs.jpg |
Re: 1972 Jimmy + 5.3/4L60E/NP205
Here is the reducer a fellow board member (shears) has used to reduced the pressure. His pump was bubbling from so much fluid flow and causing his pump to starve.

Re: 1972 Jimmy + 5.3/4L60E/NP205
Thanks for the info Keegan !! Showing the location of the AC compressor answers my questions. Like I said, i'm still not sure if I'll be running AC or not, but if there's clearance issues using the OEM compressor I may just machine custom brackets and use a Sanden compressor. I'm hoping to start my build thread in a few weeks.

Re: 1972 Jimmy + 5.3/4L60E/NP205
I like the added capacity and the factory looks of the 80s fuel tank. Were there any problems getting it into place?
|
Re: 1972 Jimmy + 5.3/4L60E/NP205
No, the tank fit well. I placed the front crossmember on the frame to where the tank fits very snug.

Re: 1972 Jimmy + 5.3/4L60E/NP205
Still really dig this build man. The close-up pic of your kiddo wrenching on the engine is framable

Re: 1972 Jimmy + 5.3/4L60E/NP205
Very nice build. Keep it up!

Re: 1972 Jimmy + 5.3/4L60E/NP205
This build cost me a fortune !! I saw that Dakota dash and I just had to have one. Damn you Keegan! LOL

Re: 1972 Jimmy + 5.3/4L60E/NP205
With some help from LS1Nova, here is a quick teaser. This was just a temporary hit to see if the thing would actually run!

Re: 1972 Jimmy + 5.3/4L60E/NP205
fast forward:
Time to put the body back on! Originally I thought I was going to have to drop the frame down as low as I could and bring it in from the rear of the truck but with the help of my wife and a 9000lb Harbor Freight winch bolted to my garage floor we were able to swing it in from the front! Installed all new 4:56 gears front and rear. All new bearings/races and seals in both axles and went with a new Eaton Posi unit in the rear. Also just because, bought new axle shafts for the rear as well. Bought all this thru Yukon Gear and Axle. Their parts are the best IMO. Installed all brand new MOOG suspension parts. Everything up front is brand new MOOG. Tie rod ends, drag link and drag link ends, upper and lower ball joints, etc. New brakes all around. Used the CaptainFab rear brackets and calipers / rotors / lines from his recommendation list. I got a hydroboost from a 03 denali and bought the CaptainFab mounting brackets. Had to swap out the reservoir (not pictured) for one that didn't have Active Brake Control - note the front nipple for the active brake. Got with Hydratech and they got me the correct lines and fittings and everything went together seamlessly. Bought a new steering gear box from RedHead and a new intermediate shaft from CPP. Installed the AC Delete cover. This was a task and took lots of mock ups. Bought Doug Thorley Tri-Ys. (the big ones). I bolted on a TBSS manifold and just didn't have the "look" I expected. I know they work, and look good once ceramic coated, but bare, they look cheap so I opted for a good set and went with Doug Thorley. All in all they fit great. Even installed the Lokar ACA-1800 shift linkage and it clears. (barely). Also went with the Entropy radiator and electric fan option. Fit like a glove. When I had BP Automotive I had him wire it for the 2 speed fans. Both fans run at low speed once they reach temperature. I haven't had the truck running long enough for them to kick in high gear but I upgraded to a 145 amp alternator to make sure I had the bases covered. The Entropy radiator I purchased had the built in transmission cooler. (hence the braided lines attached to it) Don't stare too hard at the green line, it's just what I used for my temporary steam line. Another addition is the hidden trailer hitch. I don't plan on towing (BIG) items but a small utility trailer here and there is now do-able in the future. The install was a bit of hassle simply due to the fact of the cross member location for my fuel tank. A bit of patience and I got her stuck in there. I am currently finishing up the wiring on the front end and with my DD gauges. Will post some updated pics of that soon. Also headed to the exhaust shop tomorrow to get some pipes put on her. Right now it has open headers and it is a bit obnoxious driving around. LOL. Will most likely go with a true dual / h-pipe set up. http://i12.photobucket.com/albums/a2...psze4mygux.jpg http://i12.photobucket.com/albums/a2...psah5antlk.jpg http://i12.photobucket.com/albums/a2...pstnve5ioe.jpg http://i12.photobucket.com/albums/a2...psb0una67d.jpg http://i12.photobucket.com/albums/a2...psfjjv6zx5.jpg http://i12.photobucket.com/albums/a2...psesmpr6il.jpg http://i12.photobucket.com/albums/a2...pswibr7gd5.jpg http://i12.photobucket.com/albums/a2...psqlx4xbvw.jpg http://i12.photobucket.com/albums/a2...psbrl1jbit.jpg http://i12.photobucket.com/albums/a2...psf1let36g.jpg http://i12.photobucket.com/albums/a2...psapxkv6sr.jpg http://i12.photobucket.com/albums/a2...psu8q454hr.jpg http://i12.photobucket.com/albums/a2...ps2k95qidh.jpg http://i12.photobucket.com/albums/a2...psgjlftgpm.jpg http://i12.photobucket.com/albums/a2...ps8qim93cu.jpg http://i12.photobucket.com/albums/a2...psaepghp9p.jpg http://i12.photobucket.com/albums/a2...ps569zzpkd.jpg http://i12.photobucket.com/albums/a2...ps4zjh6svf.jpg http://i12.photobucket.com/albums/a2...psfalirldj.jpg http://i12.photobucket.com/albums/a2...pscrgg1io3.jpg http://i12.photobucket.com/albums/a2...pseq9deefs.jpg |
Re: 1972 Jimmy + 5.3/4L60E/NP205
Thanks for those pics !! I'll be getting ready to put the body back on mine soon also, and was wondering how much clearance there would be between the firewall and engine. The close up pics of the shifter linkage also helped. I was planning on using a design similar to the factory linkage with the transmission to frame pivot, but this looks much simpler. Did you eliminate the detents on the original steering column? Did you change the shift indicator lens to match up to the 4L60E? There's none available for the non-tilt columns, so I modified one designed for tilt with a 700R4. Not perfect, but will do for now till something better comes along.
One last question!! On the power steering pump, which pressure regulator did you use? The one that came with the 5.3 or the original 1972 one? Thanks, Dan. |
Re: 1972 Jimmy + 5.3/4L60E/NP205

I didn't modify the steering column at all. There was enough space to get all the way down to 1st gear the way it was. Is that what you are asking? I haven't changed the shift indicator YET. Mine is a tilt but I plan to because the wife will be driving it sometimes and I am trying to make it as simple as possible. If I don't do it that way I may purchase the Dakota shift indicator that way it shows on the new gauges (the way I am mostly leaning to). Since you have a non-tilt I would look into that as well. My neutral safety was bad. (PO bypassed it) So I grabbed and new one and it works great. Only starts in park or neutral. As far as my steering pump. I used the factory LS PS pump. The lines/fittings I got from Hydratech were for the LS pump, to the hydroboost and for the factory steering box. It came with a (I will call it a jet, like a nitrous jet) looking fitting to place inside the output of the high pressure of the PS pump to reduce the amount of flow. He mentioned without that it could cause the fluid to bubble and in turn make the pump whine. I haven't had an issue yet, but I have only driven it about 10 miles without the front clip on it!! :gmc2: |
Re: 1972 Jimmy + 5.3/4L60E/NP205
I'd love to see some close-ups of the engine to firewall. I thought for sure there would have been tons of room, because the 4L60E plus the Advanced Adapter technically moves the engine forward almost 2 inches.
Even though I have the same Dakota cluster as yours, I want to keep the interior of my Blazer visually original right down to an AM radio. The deck will either go in the glove box or console. Keep the pics coming, I love this build!! Dan |
Re: 1972 Jimmy + 5.3/4L60E/NP205
Did you add the cross member in front of the gas tank? Is it from a 73+ chevy?
|
Re: 1972 Jimmy + 5.3/4L60E/NP205
What size and offset rims/tires? Nice stance!

Re: 1972 Jimmy + 5.3/4L60E/NP205
Did you just flip your newer style fuel tank around so that filler neck was on the drivers side?
|
Re: 1972 Jimmy + 5.3/4L60E/NP205
Did you paint the engine with a brush or did you spray it?
