Man, you really want this thing in there. Great problem-solving!

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.

No idea.. Aaron is running a vintage air system with the LT1 compressor and works just fine. Don't know if its a gen 4 magnum or not...

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.

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

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.

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.

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.

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.

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).

http://imagizer.imageshack.com/img923/4553/kh79ye.jpg

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.

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,
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.

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

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.

https://imagizer.imageshack.com/img924/9535/OW7O3p.jpg

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.

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.

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

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