Re: 351C heads on a 351W? help
hi there. putting clevo heads on the windsor is possible but i agree with 91GT347 about using aftermarket heads. these days its the way to go at the price you get them for and the performance you gain, go with the after market 351W heads. to fit clevo heads this is a brief look at what you need to do; buy and build 351 clevo heads, or for higher compression buy and build aussie 302 Clevo heads. 351W conrods, clevo pistons, pay attention to cam choice as the higher clevo rocker ratio changes cam values at the valve, modify water passages in heads, mod front engine acessory brackets, buy specific intake manifold, change pushrods, change exhaust (usually to whatever clevo manifolds/extractors fit in your vehicle when using a clevo, if available, may need custom fit) , change carby/EFI setup. now that was very breif and as you see will get expensive. the 4V heads are more for mid/top end and the 2V are more low/mid but with some port work are the best choice for a street car/truck. it was a modification that was popular in the old days! when it was to expensive to even think about aftermarket heads, and i must say that the 351W does perform really well with the clevo heads but these days i reach for the aftermarket catalog and just bolt something better on. much easier. hope this helps and if you choose the clevo head route im happy to give more advice. cheers
