Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
1 Attachment(s)
I'm finally to the "mostly clean" part of my build. I am doing a frame up on my '68 GMC custom. Cosmetically it looks like a Chevy with a '68 Chevy grill, though my plans are for no markings on the truck.
I will be installing a genIV '09 LY6 6.0L crate motor (using the ECE kit) with a 200-4r trans backing it up. The LY6 is an iron block 6.0L with VVT (variable valve timing) and the high flowing L92/LS3 style rectangular intake port heads. This 6.0L will not be efi...it will have a Holley Street HP 750 carb sitting atop a GMPP LSX/LS3 dual plane intake with an MSD 6LS-2 to read the sensors and fire off the factory coil packs. Comp has recommended a .224/.228 @ .050 and .566/.568 lift on 112 LSA tho I've been thinking bigger. The 200-4r is built to handle 500+hp and has a 2500rpm stall convertor. *edit - cam went bigger! see attached: I also have the CPP (Western) 2.5" drop spindles, tubular upper control arms, 1"/4" drop springs, drop shocks, adj. panhard, and front and rear sway bars to upgrade the suspension. I also am wanting to add rack and pinion steering, bigger brakes and rear discs, and a vintage air. As for the body...other then the addition of a cowl induction hood...the paint and body work will have to wait for me to pay off the powertrain/chassis build. :lol: The perfectly good running and looking truck I started (after setting the body on a '72 chassis a few years ago) with: http://www.lsxtrucks.com/gallery/alb...l_DSC02297.JPG http://www.lsxtrucks.com/gallery/alb...l_DSC02304.JPG http://www.lsxtrucks.com/gallery/alb...l_DSC02311.JPG ...still can't believe I tore it apart! :lol: and now.......... the chassis: http://www.lsxtrucks.com/gallery/alb...l_IMG_1007.jpg http://www.lsxtrucks.com/gallery/alb...l_IMG_1008.jpg http://www.lsxtrucks.com/gallery/alb...l_IMG_1010.jpg http://www.lsxtrucks.com/gallery/alb...l_IMG_1012.jpg the motor: http://www.lsxtrucks.com/gallery/alb...l_IMG_0937.jpg http://www.lsxtrucks.com/gallery/alb...l_IMG_0939.jpg and trans: http://www.lsxtrucks.com/gallery/alb...l_IMG_0566.jpg ....more to come later |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
i was just looking at this swap as it caught my eye being still carb'd and still have the summit page open reading about the msd box and harness.
i hope u will finish this so i can fallow along. good job so far!! |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
This is going to be really cool. Good luck buddy. I know what you mean about tearing apart a perfectly good running and driving truck. I did the same thing.
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
This is going to be a sweet truck again! :lol:
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
sweet. how much does it look like you will be spending for parts to get the engine running. ie msd box ect
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
Thanks all. And yes...this project WILL be finished...or at least the chassis/drivetrain. I won't be doing anything (other then some spotty rust removal) to the body for a while. Will have to wait for the C-5's too.
I bought a crate motor that had everything on it but no harness and no ECM. I knew I wanted to go carb'd on it so whatever the cost was going to be...was whatever the cost was going to be. Later I decided to sell off the EFI/VVT stuff that was on it. The intake was about $450 I think, the 6LS-2 MSD box $329 fires the OEM coil packs, Holley HP 750 $489, GM fuel pump $89 plys misc. items. I also bought a new idler pulley, starter, alternator, and ps pump as they didn't come with the accessory drive bracket. I also need a new cam as the VVT one needs to come out and go to another member. If someone had their own carb (that would be a good fit) already, they could save the carb cost. And btw...there are cheaper intakes for both the cathedral port and even the new rectangular port heads as long as a single plane is OK. |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
how big do you plan on going with cam. Not sure how much you are into ls engines but patrick guerra on ls1tech does a really good job at specing custom cams to your setup. he speced me one for my 5.3 ls silvy and i was pretty happy with it. he goes by patrick g. on ls1tech.
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
comp spec'd me one, just thinking I want to go bigger. I may go with the 2 piece timing cover so later I can upgrade.
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
well I got the front crossmember bolted in with all new grade8 hardware, got the poly bushings installed in the trailing arms, and got the trailing arms mounted up to their crossmember. Hope to put the motor in to mock up the trans this weekend. I'll have to lift it back up to take care of the oil pickup tube and oil pan after I get my new cam in.
guess I better order that dang thing, along with stiffer springs and good push rods...another "to do" for this weekend. Oh...I need to find a valve spring compressor for use removing the springs while the heads are on the block too. They're sooo expensive for what they are! |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
68 are you talking about compressor tool being to expensive?
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
valve spring compressor for LS2/LS3 style heads, while they are still on the block.
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
Cool build. Will be a great truck. Already was really nice!
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
can u tell me what front bumper ur runnin thks
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
that bumper came from LMC trucks I think. I was getting ready to buy one from LMC and I found this one on the web for like half price. It had been mounted and removed.
The lights are fairly bright, but if your truck has alot of rake...its hard to get them pointed far enough out to help much...other then lighting up the sides of the road better. My truck is getting lowered and a slight change in stance...which I hope will allow me to aim them better. |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
I love the build, I'm putting together a carbed 5.3L right now too, won't be anything like your L92 beast though. I know you didn't ask for votes, but the truck looks great without the cowl hood...just had to throw that in!
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
Thanks! I donated that hood to a guy that did some work for me when I took the truck apart...so I have to replace it. Don't really need a cowl hood to get it all in...but I've had one planned for a couple of years. we'll see.
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
well my build fund finally got a small shot in the arm...so all the cam stuff is getting ordered in the next couple of days. still contemplating going bigger....but we'll see.
also....I hate to do it but I'm cleaning up my 383 stroker to get it ready for sale along with the turbo350. It will be offerered as a "complete" motor...just like I pulled it...March serpentine accessory drive, Holley carb, HEI dizzy, fuel pump, starter, headers, just hook it all up. The purple cleaner I used seems to attcked the clear coat on the brackets, pullies, and the finish on the Proform bowtie valve covers. So its discount priced, as is the turbo350. I'll list a link to the for sale thread on it when I get that far. Someone could buy the turn key package deal of engine and trans for less then a long block crate motor and have a stronger motor to boot. |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
Well I mocked up the carb on the motor and found my new airfilter to have a 3" drop base that doesn't look good...so its sitting on a chrome base right now. ALso working on the front suspension. I need to finish putting the ball joint and cross shaft in one more lower control arm, paint the springs, then install with the new drop spindles. I hope to make some noticable progress over the next few days.

Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
I just love how good these engines look with carbs on them. It is like they were made for one. Looks like nascar engines. MMMMM:metal:
Also if i would have seen your 383 for sale befor i decided to go lsx that sucker would have been mine. Looks amazing. Great price too. Should sell fast. |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
I got a new oil filter and some oil for the 383 today. I'll drain it tomorrow and let it sit for an hour or so and then put the new filter on and fill it up. That way if nobody buys it...and I've had some low offers...it'll be ready for storing a while. I feel the motor and trans are too good to give away... so I've been fairly firm on price with only a little flexibility. If it doesn't sell here, I guess I'll offer it on CL...probably for just a bit more.
Oh...and it got a new 3" air filter too to replace that 2" one in the pics. Got the other lower ball joint in and after fighting with it for nearly an hour...the lower cross shaft in. It kept binding and after several attempts I finally put a wire brush on my drill and cleaned out the threads in the control arm. Then I threaded in the problem side a good ways 1st, and finally got it all to go together w/o binding. I still need to drill the holes for the new ECE LSx motor mount kit and set my engine and trans in to mock up everything. |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
Is smoking deal for someone. Good to here you won battle with arms. Looks realy good.
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
well...I got the crossmember all tightened down and the ECE kit partially bolted down with everything slightly loose to move it around...and make it crooked. :lol:
anway...I've got the motor bolted down in the frame now. I just need to bolt up the trans and figure out where everythings going to sit, mark it...then pull it all back out...drill holes for bottom of ECE mount, drill holes to bolt in trans crossmember if needed, and then install the boxing plates. Once the cam work is done...I can put the motor back in. OH......I guess you guys want pics? OK...coming up in a bit! :lol: |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
Here's a few shots...I'm going to bed. :lol:
It just mocked up for now...and partially supported by a jack and jack stand: http://www.lsxtrucks.com/gallery/alb...l_IMG_1080.jpg http://www.lsxtrucks.com/gallery/alb...l_IMG_1077.jpg Looks like its pretty tall? http://www.lsxtrucks.com/gallery/alb...l_IMG_1079.jpg about an 1" of clearance with LY6 truck pan: http://www.lsxtruck.com/gallery/albu...l_IMG_1068.jpg LY6 (iron 6.0L w/L92 heads) exhaust manifold w/o shield: http://www.lsxtruck.com/gallery/albu...l_IMG_1072.jpg |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
Nice!!!
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
doesn't that exhaust manifold with the shield off look like a cast iron shorty header?
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
They do. Look way better then my maniflods nonflowing self.
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
Man thats 1 tall intake when you look at it from the side like that,It's cool though
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
Yes, I think its taller then some of the single plane intakes. Thats why I measured one side shot...wondering if it will all fit under the hood!
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
narrowed the cam down to 2 choices...tho my foot says #2.....* is my 1st choice
*223/231 @ .050 - .610/.617 lift - 112 LSA or 227/235 @ .050 - .614/.621 lift - 112 LSA |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
112 lsa, should be nice & choppy!
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
stayed with the Comp LSr, the 273Lr HR12... 223/231 @ .050 .610/.617 112LSA cam, bought the Patriot Gold kit with double springs and titanium retainers and locks. I got the Crane spring tool to change out the springs and all while the heads are still on and a pushrod checker to verify what pushrods I'll need. Also got all the LS2 front cover and sensor stuff to replace the VVT stuff along with a bunch of ARP bolts...and a flexplate kit for older transmissions to go with my GMPP adapter. Between it all I should be able to mate up the trans, and I'll just sell the one I don't use.
Trans has been painted and the new energy suspension mount will be here in a few days. The front control arms are ready to go so I'll be bolting in the new drop spindles this weekend, hopefully mocking up the trans, so I can install my frame boxing plates, and also painting and bolting in the rear end...or maybe I'm being too optimistic. :lol: oh yah........I almost forgot...based on various tests results I've seen, similar cams, an identical block/heads config.....this cam should push the motor to well over 500hp (probably around 535hp) and roughly 450tq. Not bad for normally aspirated w/o nitrous. |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
After we both get these done we will have to meat some place. Maybe we can have a LSx swap...meat. That would rock.
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
made a little progress
got some parts in: http://www.lsxtrucks.com/gallery/alb...l_IMG_1145.jpg front suspension ready to go together: http://www.lsxtrucks.com/gallery/alb...l_IMG_1136.jpg painted the 2.5" drop spindles with a "cast iron" coat of paint: http://www.lsxtrucks.com/gallery/alb...l_IMG_1138.jpg springs were black...now they're silver: http://www.lsxtrucks.com/gallery/alb...l_IMG_1143.jpg got the trans painted..its "graphite, and darker then it looks: http://www.lsxtrucks.com/gallery/alb...l_IMG_1140.jpg also bought ARP water pump bolts twice (ooops)...so if anyone needs a set... http://www.lsxtrucks.com/gallery/alb...l_IMG_1149.jpg |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
This is looking good! Are you using the stock truck pan? Does it hang lower than that front crossmember?
|
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
Thanks! I'm using the stock LY6 truck pan with the ECE mounting kit. The back of the pan is about even with the bottom of the crossmember but...I have the motor supported in the back on a 2x3 and jack stand right now. If the angle changes much with the trans hookup (and removal of support)...it might be 1" or so lower at the back of the pan?
http://www.lsxtrucks.com/gallery/alb...l_IMG_1136.jpg |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
got some more goodies today....including my cam!
http://www.lsxtrucks.com/gallery/alb...l_IMG_1150.jpg http://www.lsxtrucks.com/gallery/alb...l_IMG_1151.jpg more pic updates coming soon.... |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
well, I got the trans in and tossed in the drive shaft (not cleaned/painted yet) to see how things looked.
http://www.lsxtrucks.com/gallery/alb...l_IMG_1197.jpg I also tossed one of the front 1" drop springs and 2.5" drop spindles on the tubular upper and stock lower control arms to see how it looks. http://www.lsxtrucks.com/gallery/alb...l_IMG_1193.jpg http://www.lsxtrucks.com/gallery/alb...l_IMG_1199.jpg the base for the air cleaner I got is a 3" drop so it looks kind of funny...and will be replaced with a "flat" one. http://www.lsxtrucks.com/gallery/alb...l_IMG_1194.jpg |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
got a little more done. CPP front 1" drop springs, 2.5" drop spindles, and CPP tubular upper and stock lower control arms all installed with new ball joints/bushings...and now waiting for the new brakes to arrive. I need to get rear axle installed so I can determine if the motor needs to come back some or not.
http://www.lsxtrucks.com/gallery/alb...l_IMG_1210.jpg http://www.lsxtrucks.com/gallery/alb...l_IMG_1211.jpg the very back of the oil pan has a dropped area around the drain plug...that hangs maybe 1" below the crossmember with the ECE kit and an LY6 oil pan. http://www.lsxtrucks.com/gallery/alb...l_IMG_1212.jpg |
Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build
She should really come alive with that new motor cant wait to see her done..
