1990 Silverado - LT1 & six speed, help needed
First off I hope I am on the correct forum for this question as I am fairly new to this website as well as this kind of swap as I am a youngster trapped in the body of a 67 year old man and thankfully have never grown up.
In my shop I have a 95 Camaro 5.7 aluminum head LT1 engine complete with the #16188051 computer, wiring harness and the T56 which for 1995 was the B-W 6 speed manual transmission. Both have been somewhat rebuilt and the engine 060. over
After looking for something to put this setup into, only yesterday I acquired an unmolested stock clean 1990 Chevy Silverado 350 TBI with a serpentine belt system and the 5 speed manual transmission and I am sure you know what exactly has to be done. I realize that this swap has got to be fairly easy if I have all of whats needed, but I don't know all of whats needed because I have spent most of the past 20 years working on my 64 Plymouth 480 hp 2400 pound Signet with the rest of my time freehand pinstriping
and driving an AstroVan to do my work.
After reading numerous websites I figured out I don't understand half of what I've read because it seemed like it did not pertain to my situation as most of the trucks either had a V6, 5 speed to begin with and the setup was for a police car engine and an automatic transmission to swap in. They have spoken about notching the frame to accommodate the A/C compressor from the serpentine belt on the LT1 unless a Corvette system is used. I was wondering if part of the truck's 1990 350 TBI engine serpentine system can be somewhat interchanged with the LT1 serpentine system just for the A/C compressor, so that the A/C compressor could remain on top like it is stock on the truck so the frame would not have to be notched.
There is so much I do not know but I do want to learn from you as to exactly what is needed as I am not going to be deterred from this setup as others have tried to on other projects I've done while living in this part of the country. I have been pinstriping for well over 50 years and I am from Lawn Guyland Nu Yawk and living in southern Oregon for the past 15 years so you could imagine between my accent and my streetable racecar how well I get along with these kit car plastic streetrod people while everything I drive is American steel and quite different from them.
So, what do ya think, can you help me and maybe down the line, I can help you.

Hey Joey, welcome to the site! Nice pinstripe work, I checked out your portfolio, very impressive 
I don't have the answers to the questions that you're looking for, but will give you a bump to the top in hopes that someone does. I'm not too familiar with the new style LT1 engines, as is the same with many around here. This site was originally a spin off of LS1Tech which is a Chevy GENIII-IV site, so that's where many of us find our background. Hopefully you find the info that you're looking for!

Don't think there's any way to use the truck belt drive on the LT1 bc the water pump is driven off a shaft that comes threw the timing cover. Think the pass. motor mount is moved back on the LT1 so the ac comp. will fit. Hope this helps a little.
