Hey guys. My 91 G-30 mini school bus has issues. Could be a blown head gasket only, or it could be worse. It's been sitting all winter waiting for warmer weather to come along before I start turning wrenches on it. While it's been sitting, I've been watching the local classifieds waiting for a killer deal on a long block to come along thinking I could snatch it up and have it ready to use if I tear into this thing and find a worse case scenario. I figured I could re-sell it if I didn't need it for what I paid.
Well, I struck gold yesterday. Got a 6.5 turbo motor for $175. It came out of a roll-over suburban with 91k miles on it. Complete motor fan to flywheel. I talked him down to that price because I didn't take the IP, turbo or exhaust manifolds.
I know it's an old trick to bore a stock 6.2 out to use 6.5 pistons, as this lowers the CR down from 21:1 to 17:1, and puts less stress on the engine, but I just want to double check everything before I give the project a green light.
Will ALL of my accessories swap over to the 6.5 long block? Will the stock 6.2 IP have any issues? Basically will this work to convert a computer controlled turbo 6.5 over to a non-turbo 6.2 environment?
Any assistance or advice is greatly appreciated
