Gents, I am playing with a 54 Mercury, 256 ci and a Mercomatic. The 256 is a chronic smoker and is to be replaced. I just bought a 292 ci that is missing the following: intake/carb, exhaust manifolds, water pump and distributor. The block casting is C2AE (62' to 64"?). The head casting is ECZ-C (56"?). Now the questions: Will my 256 parts fit the 292 (except distributor)? What would be the best distributor to use with this combo (256 carb is a Tpot)? Suggestions for an eventual Intake and Carb replacement? How do I determine what ECZ-C heads I have (compression ratio/HP)? The engine was a non smoking, good runner but has been sitting for a year. Since it?s out, is there any weak link or "might as well replace it" parts that I should consider? Sorry for the diatribe, but I?d like to do it right and I?m new to Y blocks. Thanks, John
