My car's engine, V8 302 Automatic, doesn't have much room. Would it be possible to put in a turbocharger and if not is there anyway to make room?
This will give you ideas... But a stock engine from '70s won't live long under boost... http://mmb.maverick.to/threads/subtle-74-maverick.116184/
I did my car with factory shock towers. Been turbo for over a year now. Runs awesome. I ended up grenading a shortblock due to rev limiter being set too high for factory rod bolts.
I am no expert on boosted applications but I can tell you forged pistons, good aftermarket rods and ARP main bolts/studs will be a good start. I also understand the rings need to be gapped correctly to keep from breaking the pistons.
Sounds to me like you should buy a ready built, boost friendly short block then add the remaining components...
