Re: LT1 GenV swap
Great work! I'm looking for more info on the compressor for the AC. I have a Gen 4 Magnum Vintage Air unit, just found out they do not make any brackets for the Gen V LT1 motor. I would like to mount it back in the original location as I have cut my center cross member on my 57 chevy, so lots of room.
My Vintage Air dealer suggested I use a fixed displacement compressor from a 2008 to 2010 LS block and modify the mounting brackets from there? Any other company making components for there AC systems? Thanks in advance. |

Re: LT1 GenV swap
Thanks 87chevy.com spoke to vintage air this afternoon, they told me that my Ac compressor from my 2015 Serria Denali 6.2 litre has a variable speed compressor, it will not work with any vintage air system. Vintage air must use a fixed displacement compressor?
Could you post more info about this, I believe Aaron is running a factory compressor as you stated or give me contact info? Really stuck for ideas, wanted to run all factory parts on this engine, just want to keep making progress on my install. Thanks in advance. |

Re: LT1 GenV swap
Just went through the whole thread, and got plenty of information. Thank you. I have a 2016 L83 with the 8L90, and looking forward to getting her wedged in to my 1992 single cab silverado. I just ordered the accessory bracket from DD, along with Sanden compressor and adapters for corvette water pump. I was also going to order the hydroboost brake booster, but just don't have enough information to pull the trigger. I was hoping to get you all's opinion. Thanks in advance for any information, and great thread.

Take a look at a 2000GT ford Hydro boost or A Astro Van or maybe a 3/4T Chevy or GMC

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. Clint

Re: LT1 GenV swap
Feeling confident the a/c compressor adapter mess is sorted:
![]() Plenty of frame rail clearance ![]() 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. ![]()

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. ![]() Clint

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
![]() 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.
![]() 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) ![]() 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. Clint

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
![]() ![]() 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, Clint

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. ![]() 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 ![]() Clint

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. Clint

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.
![]() ![]() 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. Clint

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!
![]() 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 ![]() Clint
