Its funny how there is a thread going about this right now...I just bought a 1957 235 out of a car. My 216 was burning oil really bad so Patrick's told me to find a 235....I found one on Tuesday not far from my house...Phillip, Patrick's son sent me the short water pump, pulley kit for the motor...I also bought some hearders, dual manifold, alt. bracket. You have to reuse the bellhousing, clutch, flywheel, starter...the motor should be going in on Monday...after I change all the gaskets on the 235....
