help a young scrub out here and school me on the diferences between a 351C and a 351W. all i know is that the 351C has 4-blot mains and is more solid (so i've been told) and that it comes in a 2v and 4v, the latter having canted valves and larger more rounded intake and exhauset ports. give me some pro's and con's . although I'm more than happy with the 289, I hope someday to drop in a 351, a 5 spd auto and a 9" rear. So I want to keep my eye's out for some of this stuff when I'm out off to colege next year. ya never know when one will show up!
