Thank you for the info, I was also reading that one would work off a 2010 Chevy 2500? I will take them all into consideration and hopefully make the best choice. Thanks for taking the time.

Re: LT1 GenV swap
 

The hydroboost isn't a necessity, but definatly will give you clearance between the valve cover and it's trim cover. I have the mltor as far back and as low as it can go with clearance of course and the beauty cover to booster has only 1/4-1/2" clearance iirc.

Re: LT1 GenV swap
 

Finally getting back at it with the final install. Got the motor, trans, and oil pan assembled and installed. Removed the driveshaft yoke from the Tahoe driveshaft, lined up the wear marks.. turns out it's exactly the same length as the one that was in there, 57" xe ter to center. Just need a new u joint and done! What were the odds of that.
Picked up 2 different length belts for the front accessory drive but didn't get that far today.

Re: LT1 GenV swap
 

Feeling confident the a/c compressor adapter mess is sorted:

https://imagizer.imageshack.com/img924/7606/BEEor3.jpg

Plenty of frame rail clearance

https://imagizer.imageshack.com/img922/8272/hw6SRO.jpg

The motor mount stand is close, but a tad bit of trimming for when the motor mounts wear/sag is needed.

Shortened the stock transmission dipstick tube. Measured the bottom of the tube to the cold mark before modding it. Made the short end a slip fit so it can beheaded or tig welded. Just need to test fit one more time before joining them together. The dipstick indicator will just get cut and welded.. similar to the ls1 dipstick.

Re: LT1 GenV swap
 

Small victory! Got the dang trans dipstick tube installed. Had to loosen the cab bolts which i had loose already and raised it up (for quickest and easiest way to get it installed).

Looks stock and saved from buying an aftermarket one. If it wasn't shortened, it would be about 6-7 inches longer. :(

Re: LT1 GenV swap
 

Stock fuel line segment from the high pressure fuel pump to Russell 3/8 fuel rail adapter, then to a 90 socketless was doable, but getting close to the stock brake booster. A 90* to -6 would be the ticket. I bought the socketless fittings and aeroquip hose so the 3/8 efi rail 90 adapter to braided connection would work great if I had the braided hose and fittings to begin with :( otherwise the flex line I would be making would be around 60 bucks.

I cut the crimp fitting off of the stock line and slid the stock hose off and installed the socketless hose on and oetiker clamped it. Installed a spare socketless 90* fitting instead of the one I planned the fuel/trans line build around, black😯. Be a good test mock up. Gonna make a pitsop at the hardware store and pick up an insulated hose clamp and fasten it to the stock bracket that was on the hardline and call that done. Since its not secured in the pic it just rests on the beauty cover.

Re: LT1 GenV swap
 

Finally making time to tinker around. Decided to change the tensioner placement. It seemed like it applies tension to the belt, but I think it was at the edge of the belt and it was acting more like an idle pulley vs a tensioner. Basically, i could pull the tensioner with the ratchet attached and max it out (pulling the belt tigher without too much effort) and if that happened under high rev, quick rev, i think it would be belt slip and or belt damage .. maybe. Scooted it over which now it's actually applying the tension to the belt. Needed to add an idle pulley to clear the tensioner placement. Pesto, completly satisfied with the accessory drive.

https://imagizer.imageshack.com/img922/5509/Mwuqgi.jpg

Belt tension is between minimum and normal belt length marks with a new belt so after a few miles it may stretch a tad and be even closer to the normal mark (middle mark)

https://imagizer.imageshack.com/img924/52/GBSRXv.jpg

Next rockauto order, I'll try a 82mm idle pulley by the power steering pump If it doesn't get closer to the middle mark.

Re: LT1 GenV swap
 

Went backwards to go fowards... modifying the modified harness. Looks waaaay better with the harness ran out the back of the engine. Making a new coil,map,ect,oil psi, and dod oil control harness. Got all the terminals so no splicing here :)

https://imagizer.imageshack.com/img923/598/eOPDx6.jpg

Will be an upgrade from the current harness mod I do

Re: LT1 GenV swap
 

I am searching for an upper radiator hose solution. There's not too many square bodies with a l83 swap, but an ls2/3 swap / waterpump could the equivalent answer. If anyone has any recommendations post up.

The lower hose is no surprise, ls1 5.3 truck hose, trimmed of course.
Thanks,

Re: LT1 GenV swap
 

Seen somwthing ubwant expecting to find.. a problem with the compressor and it's comnector locations. Specifically the solenoid valve on the bottom. With the engine moved as far back as I could get it, I found out that the solenoid connector is about 1/4 ish inch from the motor mount adapter plate. Maybe I could have installed the connector on the compressor and then installed it to the engine but would have been way too close if it even fitted altogether.

Solution make it fit. Lol

Remove the soloind, plug the solenoid bore and grind the compressor housing so the solenoid could be rotated.

https://imagizer.imageshack.com/img922/1632/pAe88m.jpg

Used one of the end cut carbide burr bits and make short of the modification

No before and after pictures but the red lines is what was removed from the other side so the solenoid could be rotated

Re: LT1 GenV swap
 

Satisfied with the upper radiator hose choice. Coukdnt find a one liece solution. This one required 2 different hoses with the single adapter. If the adapter was maybe 2 inches longer the stock Fbody hose would work without a 2nd hose.

Still need to sort out the e-fans.. among other things.. also got the ac lines braze together. Pleased with the outcome. Both ends will get 90 degree fittings and it will match / run along side the heater core lines.

Re: LT1 GenV swap
 

Hadn't made much progress, the fuel pressure regulator housing I bought didn't fit the regulators I had - so it got sent off to the machine shop, been there for a week or 2. Got the temporary fuel pump setup ready. I say temporary since the pump data sheet says it can draw a few more amps than the connector can support... so I will measure it once it's up and running. I have a backup plan just incase.

https://imagizer.imageshack.com/img923/3826/ZbreS0.jpg

https://imagizer.imageshack.com/img924/7426/39ncuo.jpg

Made a fuel pump mount to hold the pump on the 5/16 tube, used the flex intank hose just to be e85 safe. If I wasn't going to run e85, stock setup would work. Couldn't find a single e85 submersible rated hose though.

3/8 feed, 3/8 return and 5/16 transfer from the other tank.

I am following this thread with interest as I am putting this same engine into a 88 single cab swb. I have had the engine and truck for a while but was waiting till the parts were available.

Re: LT1 GenV swap
 

Love it when a part just pops out of the computer screen. Ok, it didnt just pop out, it was a another part I would want to get made but didn't expect to ever get our of the computer $. Big thanks to the machinist!! Parts are perfect!

https://imagizer.imageshack.com/img924/2182/IXJFFL.jpg

Two of a kind lol. If there's any interest could offer them up, but for now, only one. Uses p-6 fitttings and proper terminals for the current , Delphi metri-pack 280 / 150 terminals. That was the whole point behind this part, so there's no oversized wire on an undersized terminal to create a situation.. it's gonna be a daily driver and don't want any nonsense problems, only traction problems :)

Was going to use the modified stock we sender and try the racetronix style setup but wound up not trying it. Have a few of the bulkhead and connectors if anyone wants to give it a try. Original bulkhead wouldn't work for the l83 swap since the pump needs 2 wires, and the sender needs 2 separate ones.

Slowly getting there.. Not really motivated lately. Think it's slowly coming back :)

Drew up and cut out the transmission cross member pieces out. Didn't have the stock one, and if I did, probably still wouldn't use it lol. Waiting on the hole saw bit to arrive to finish it.

Similar design I used on the LS BMW

Plumbed the fuel system. Ran out of the push loc fittings, needed one more 45*, so a 90* was put on just to get it finished.

Nice work and problem solving all through the build! Any updates?

Re: LT1 GenV swap
 

Just got it started a few minutes ago after some quick trouble shooting... now it's going on hold again. Have another harness to mod, waiting for a set of custom header flanges to arrive so I can make a set of long tubes for it.
Clint

Re: LT1 GenV swap
 

Clint, I have a set of LT flanges that I won’t use. I don’t remember what I paid for them but if your interested...

Re: LT1 GenV swap
 

87chevy, what did you use to control your trans?

I found out the trans is a 2013 and the motor/pcm is a 2015. I’ve tried 3 tuners and no luck so far. It’s stuck in 1st gear.

Re: LT1 GenV swap
 

How do they know its a 2013 6l80? Using the stock 2015 ecu... do you have HPTuners? If so you can read out the data, post that on HPTuners site and ask of they can do a segment swap. I've only rehashed 2015's to 2014 If they didn't have vats2.
I got a 2015/16 flood transmission taking up space on the garage. Would more than likely need a rebuild just to be safe. Havnt taken the pan off, just stuffed it under my table saw.. I bought it with a hydrolocked motor for mockup before in-game across the good one I have now.

Re: LT1 GenV swap
 

Ya know... I think I have been BS’d again. Spoke to clinebarger today, just need to change out the valve body/Tcm. He said the only issue is when they come from different types of vehicles, 2013 car vs a 2015 truck, also he said the guy doing the programming could have fried it if he doesn’t have the correct equipment.

Thought?

Re: LT1 GenV swap
 

The tag on the side of the trans decoded it’s a 2013...


I don’t have squat, I’m relying on others and what they say..possibly my issue all together.

Re: LT1 GenV swap
 

Hopefully you get the trans sorted out.

Got another swap harness wraped up.

https://imagizer.imageshack.com/img924/4339/eNu2aM.jpg


Still waiting on the header flanges, hopefully they will ship out late this week. Once headers are made I'll reinstall the fenders and hood and take it around the block.

Re: LT1 GenV swap
 

Still haven’t gotten the trans fixed. New VB/TCM and still can’t program the trans TCM. Checked continuity from TCM plug to data lync connector and all is correct there.

My head is swimming in a lake of frustration on this...could there be something wrong with the ECM?

Re: LT1 GenV swap
 

There is only 2 other wires that would be modified for the TCM, battery constant and the crank/run.

Re: LT1 GenV swap
 

Hours and hours worth of cad gets me this far. Exhaust ports exactly centered on 1 3/4 tube. I chose 1 3/4 since I have lots of bands left over and the port as well, when a 1 3/4 tube is shaped like a rectangle, the same size. I'm not to crazy about the flanges I ordered and received so drew my own.

Adapters screwed into the nutserts

https://imagizer.imageshack.com/img923/3065/M8spVt.jpg

Just threw some tubes on it just cause.

Mann, the MDF flange is way better than a steel flange and a starter tube in said flange with the insert adapter.. this way is much much much more stable and won't fall out! So wish I had done this on the last set of headers I built!

Hope to get the driver side modeled tomorrow and maybe get started on chopping it out of tube. Still need to make another saw fixture for the u-bends

Re: LT1 GenV swap
 

Very cool!

Re: LT1 GenV swap
 

87, do you do tuning? If so, would you mind answering some questions for me. I can get a tuner here that is willing or able to fix my issue.

Please pm me your number and best time to call, if your ok with me calling.

Thanks

Re: LT1 GenV swap
 

PM sent

Got the driver side mocked up. Wound up sending my drawing file of the header flange to the later cutter, was not happy with the stainlessworks flange. Those should be done in a few days.

Thought about sending them out once I have them welded up and sell them but speed engineering says they will be making them at some point so not sure if its gonna be worth it.

Mocked in the a massive 19" 600 watt pwm fan. The radiator core is 19" tall.. think it was meant to be.

https://imagizer.imageshack.com/img921/9332/SkoSFc.jpg

https://imagizer.imageshack.com/img922/1300/7CXGro.jpg

Shows the gap between fan and core, will get pushed away a little more
The wood strips are 3/4, gonna use some 1x1 aluminum as a frame and rivet a piece of sheet to the frame.

Since I do t have a metal brake wide enough for the sheet metal, the 1x1 square tubing frame should work out. I'll bend a piece for the top, to cover the radiator and one for the bottom part so fan pulls all the air from the core area.

Need to do some research on what other companies use as far as thickness and see who has a sheet or scrap large enough for this project.

New header flanges should be in Thursday along with the u-bends.. and I work the following Saturday :(

Clint

Re: LT1 GenV swap
 

Recieved the header flanges and other bits today

https://imagizer.imageshack.com/img923/9753/ESKhhH.jpg

Extra bits that should make header tube forming easy once the transition from port shape to round is made

https://imagizer.imageshack.com/img921/7168/0HeDHC.jpg

Game plan is to use a grinder to make the transition and simply run a bolt through them to align it, then cut some grooves length wise and weld a bead in the groove. Cut some le grhs of tube and take em to work and use the press to form it.. could use a hammer .. well will see.

Using a hammer on the exhaust tube forming cone took some serious swings but the press made easy work of forming my transitions.

2.5 to 3" yes they sell transitions but way over priced for what they are. 2 cheap transitopms that arnt as smooth as the ones the fool made cost as much as the tool.. no brainer.. and the good ones are $$

https://imagizer.imageshack.com/img924/9886/OjFpCE.jpg

For kicks I shrunk a 3" to 2.5.. smooth as butter!

Made an extra set of flanges if anyone is looking to make their own headers. I got plenty of extra inserts to make an extra tube former.

Made the back fence tensioner out of a scrap away bar link. A regular bolt works too. I had to use a regular bolt for the stait cuts due to the lack of space.

Makes it easy as pie to duplicate the plastic version. The back fence makes it so much safer too. Also works for any size tube if the chop saw can handle it. Metal saw blade is the best thing as the abrasive deflects to much to be accurate

Re: LT1 GenV swap
 

I've made a L83 swap harness for someone and they bailed. Will fit short beds/long beds with stock tank location or short bed with cell in the rear between frame rails as this one was made for a short bed with a cell on the rear between the rails. Can provide measurements if needed. 750$ shipped with exchange of a stock harness.

https://imagizer.imageshack.com/img924/4339/eNu2aM.jpg

Has provision for driver side alternator. Wires ran in loom and has ECU pins already crimped incase driver side alt is needed.

Harness is e85 ready

The white wood panel is just to hold the bulkhead and fuse block during wiring it. Cad drawing with the template to cut out will be provided.

8 ga power feed, starter, ignition and fan output (pwm) are the wires needed to be connected.

Has a separate interior harness and fuel harness for ease of install.

Even though this is not the for sale section, figured this would be the best spot for it.
