    Cleavor motors run great!! With all the hi-flow Windsor Aluminum heads on the market today, I haven't put a Cleavor together for a number of years, but they run strong. Actually, the 4V Cleveland heads almost flow too much air, really gotta twist the motor to get the most power out of the heads. I used to use the 2V castings, seemed to be a lot more streetable setup.

    351 to 427


    If you are going to drag race, use the cleveland heads. If it is a street engine use a good set ot winsdor heads. GT40 ford heads or V8 explorer heads are the best factory heads. I have a set of world product heads on mine. They have 2.02 intakes and 1.64 exhaust valves. I am running about 9.75-1 compression with a ford motorsports 351 cam with 290 degrees on the intake and 300 degrees on the exhaust with 4.98 inch valve lift. An Eldelbrock air gap manifold with the cast header type manifolds from a 66 hi-po mustang 289. I ported them out as far as I could go. and port matched them to the heads. I have this in a 1951 ford. I could not find any headers that would fit. It is backed up by a toploader 4 speed with a 8 inch maverik rear end with a set of 3.40 traction loc gears. It is all I want in terms of power. As stated earlier the cleveland heads are good in the upper RPM range, but rather flat at low end. The world products heads on mine engine work excellent for a street car. A good stout street engine needs TORQUE not high winding Horsepower.

    ...who are these "folks" who think a Cleveland's a big block?

    (thought I'd be nice to keep the moderators off my back!)

    And if you have the parts, I'd think a Clevor would be pretty cool! A great way to throw the uninitiated off, and bragging rights to boot for the uncommon!
