:bs:smilie_slap:slap:twak:smilie_slap:slap:twak:bs302's and 351's have the same block, just different heads and intakes and stuff. Don't know how to tell them apart though on the carb'd engines.
He is right the 351w has a 1" taller deck hight on the block and that is why the intake on a 351w is different from a 302. The 1" taller deck puts the head farther apart on the 351w.:bs:smilie_slap:slap:twak:smilie_slap:slap:twak:bs
Repeat after me-----302s and 351s are DIFFERENT, do a little bit of research before you give advice. Just remember, search and google are our friends.
Officially, 1982 was the last year for the 351M. mid model year engine supplies were exhausted, and the 351W replaced the M.The 351M wasn't offered in '84 model year, according to the manual I have. Look at the 8th character in the VIN- F or N is a 302, G or H is a 351W. And yes, 351/302 blocks are different.
