Years ago it was the only way to get decent flowing heads on a 302. Now with all the good aftermarket heads, not many people do it anymore. Requires some redrilling on water passages, and if I remember correctly a special intake??? Never ran one myself, have some friends that did. They seemed to work fairly well. Since so many companies started making stroker kits and good flowing aluminum heads, the Cleavor would IMO be a step backward in performance.

It will make an engine that takes a lot of rpms to work, (race track conditions) not much for the street. I'd stick with a more stock engine setup, they have proven to be much more effecient and productive. The cream rises to the top.

Cleavor
Army, sure you can. But do you want to ? A fellow, Gary, don't remember his last name, made dual plane and single plane intakes for mounting the 351C-2V onto 289/302 and 351W blocks. you have to drill some new water holes in the decks, and plug some water holes in the heads, and then you have to find one of those special intakes. I don't know if Gary still sells them or not. He called his stuff B&A perfomance. The large combustion chamers on the 351C leave you with not really inspiring compression, and the 302's valve notches are in the wrong place. The changeover also requires all new pushrods and head bolts. If you get a new cam and change to some boss302/351 style pistons, the cleavor can be a screamer, especially in a mustang with a 4spd. 400 hp is easy. But I wouldn't want to pull that same engine out of a 'stang and put it into a truck. A 351W would bolt into your truck very easily, however, and the 351W makes a fine truck engine.

Jowilker brought up a good point. The Cleavor engines will make their best power from 3500 thru 8,000 RPM..... Not really practical on a street engine IMO. If you want a more practical power increase, you might want to consider a 347 stroker kit and some porting work on a pair of 69 or 70 351W heads, or a pair of aluminum heads that offer substantial horsepower gains in "out of the box" condition.
