So last summer I got everything to work and it was a great cruiser.  AC blows cold, cruise worked even the 1988 cassette worked (kind of).
The winters are long and cold in MI so I blew it all apart.
LS3 with a 4L70E is going in.  Mainly because the  1988 350 leaked oil.
 
 
 
I’m using the Holley front accessory drive, the mid mount.  Makes a very clean and tidy package.
The Holley cast iron exhaust manifolds that I will connect to a 2021 Chevy High-county exhaust system I was able to buy off Facebook marketplace
