What are you babbling about? 351C vs 351W? There is no comparison for the stock engines. The 351C simply dominates the 351W. Then again, I view the stock 351W as a boat anchor and I cannot comprehend why so many Ford people love it.

These days the aftermarket for the 351W is far superior to that for the 351C which more than balances the scales in favor of the 351W for performance when significantly modified.

The heads for the 351C are old school technology that weren't designed nearly as efficient as today's castings. With superior technology and research, flow velocity was increased along with improved port shapes, sizes and valvetrain.

no, no, no, i'm not comaring the 351W to the 351C at all. my dad has a '70 mach1 with the 351C in it, i will have an '89 with a 351W in it. anywho, he wants some better heads for his car, he's not happy with the power it has i guess. but he read somewhere that in australia the heads were different because of the emissions or lack there of in australia, so he wants some for his mach1
