Shetland pony March 11, 2012, 03:14:57 PM Ha.I've got an idea. I've got a couple of 351w blocks, cranks, rotating assembly in my bin 'o parts....I want to find a set of Cleveland heads from a 351m/400...have the stuff machined, and build a 351 Clevor. Put it in a Mustang. Get a Boss 351 graphic for the hood.Go have fun with it.Whattya think? I've got everything but the Cleveland heads and the adapters for the intake manifold....:hick: Quote Selected
Shetland pony Reply #1 – March 11, 2012, 03:50:23 PM 351/400m doesn't have the cleveland heads on it. There is also 2 versions of the cleveland head a 2V and a 4V head. Quote Selected

Shetland pony Reply #6 – March 11, 2012, 06:20:23 PM modified heads are like the stepchild heads of clevland heads.. it's a big upgrade to drop C heads on a modified bottom end, especially the aussie C heads Quote Selected
Shetland pony Reply #7 – March 11, 2012, 06:27:41 PM Are they even worse than the 2V heads? Seems like they would be way ahead of stock 5.0 heads...lol. Quote Selected
Shetland pony Reply #8 – March 11, 2012, 07:06:48 PM i believe they are.. from my understanding, they're basically like E6 heads compared to GT40-P's, in terms of M vs C2V's Quote Selected
Shetland pony Reply #9 – March 11, 2012, 07:23:06 PM The modified heads are good boat anchors. I would encourage you to do some more research before spending any money. Either of the C heads are improvement over the M. The M motors came from trying to meet the government emissions requirements. :D Quote Selected
Shetland pony Reply #10 – March 11, 2012, 07:30:53 PM modifieds are my favorite BBF's.. they're major underdogs.. i miss my 400 :( Quote Selected
Shetland pony Reply #11 – March 11, 2012, 07:58:21 PM Why not buy a complete 351C? Just curious. :D Quote Selected

Shetland pony Reply #13 – March 11, 2012, 08:59:08 PM The reason to build a clevor is the windsor short-block is stronger and can be stroked more. A M head is basically a C "BUT" they have huge EGR ports the rap around the exhaust guide which kills flow. The best head for a clevor (in my opinion) are the ausi 2V heads. They have 2V ports and closed chambers. I would say 4V heads but they're too big for a street motor. Quote Selected
