What are you looking to put the engine into? Both engines can be built into strong performers, if you have the money and resources. The differences are the block, heads, intake, headers...everything they only share displacement. As far as which one is better, a 351W would be cheaper and a lot simpler to fit into a fox or even SN95. The 351W can be done with pre made parts, ie ones that companies make, but the 351C would require alot of custom parts. You could make a 351W with 350-400 hp easy. A 351C on the other hand, depending if you went with 2 or 4 v heads would require reving the engine to 7000+ rpms to get any power. Building a 351C with 4v heads would be a waste in a daily driver, cuse you would have to rev it to the moon to make power, 351 ci is simply not enough to make use of the heads. If you really want to use a 351C, put the 2v Aussi heads on it with the wedge chambers. Any 351C stroker would be good, but would require alot of expensive custome parts. Another route would be to build a 347 stroker. it would be cheaper than any 351 swap.

well said 89fast5oh..I thought about the 351C too but what a pain in the $ss. A 460 would be an easier swap than a 351C. I prefer the 351W route, but requires different oil pan and headers than a 302.
