The better question is whats the same, the only thing they shair is the bore and stroke, everything else is different. The 351w is basicly a 289/302 with a one inch taller deck height, so they can get a longer stroke. the 351c is a small block with a big block head. Its head has the same design as the 429/460. It also has the water exit on the block and the timeing chain is set more in the block and is cover with a flat stamping.
