The 351W is a small block motor where as the 351C is a big block in a small displacement. As far as the Windor being unreliable I would like to know how since it shares the same block as the highly reliable 302. As far as proof of the 302 being reliable I have my 88 5.0 Stang to offer up. It has

The 351C engine is the same length as a 351W, and it has a shorter deck height (351C=9.2, 351W=9.5). A 351W crank can be ground to fit the 351C block. 351C stroker cranks are cut from 351W stroker cranks. 351C heads will bolt on to a 351W block. 351W heads will bolt on to a 351C block, and you can make them work if you want to. You can mod the bolt holes and mate a 351W EFI intake to a 351C with 2V heads. When you need more room for a stroker than your 351C block will allow, you move to the taller 351W or
351W-based FRPP block. If a Windsor is a "smallblock" (a shivvy term), then so is the shorter 351C. Better yet, drop the s***ty, er, I mean shivvy terms and use the engine names.As far as "hoytd" is concerned, he is only here to troll. He's not trying to express an honest opinion or engage in a sincere debate.
The most significant difference between the 351W and 351C are the heads. The Cleveland heads are what make this engine - Cleveland 4V heads feature HUGE canted valves (intake head diameter ~2.19", exhaust head diameter ~1.71). A comparable 351W head features ~1.8" intake and ~1.5" exhaust valve head diameters. The Boss 302 and 351C engines contain the same heads.
