Can anyone tell me the specified cylinder compression needed for the 351 Windsor engine? It's in a 1991 Sunsport if that helps also.

Really? No one here has this info to share? I just have to do a compression test on a boat before I buy it...

all cylinders over 100 with no variance between cylinders more than 20%...or something along those lines.
