Question about 351 head swap

I've heard of 351 Cleveland head swaps on Windsors (ever heard of a Clevor?). Not sure if its typical to swap the 2v or 4v heads though. My guess is without a serious power adder the 4v heads are just as unstreetable on the Windsor as they are on the Cleveland. If you can figure out a way to move air at low RPMs the 4v heads can support a lot of power, though.

All that being said a set of decent aftermarket 5.0/8 heads probably makes more sense.

 

"clevor" only applies to pushrod engines

 

Isn't that what we are talking about?

 

yea but you mentioned about 2v and 4v heads

 

Ah. So before V commonly meant valve it meant venturi. So 2v is a 2 barrel and 4v means 4 barrel.

 

Ha.. that's what the heads we classified as a 2v, 4v.. had nothing to do with the number of valves. .

 

Maybe that wasn't clear enough... Sorry about that.
Cleveland 4v are 2 valve OHV heads which have huge ports so their streetability is questionable. The 2v heads are also a 2 valve OHV type but have more reasonable port sizes. The number of carburetor barrels (or venturi) was indicative of which you had so a Cleveland with the 4bbl carb got the larger ports.

 

I knew exacly what you were taking about.. good way of explaining it tho

 

The Explorer is a 5.0

 

Are you wanting to swap them to a 351w..

 

Clevland heads can be swapped onto a 302/Windsor block but it takes a special intake (You'll have to carb it or go aftermarket efi) and AFAIK nobody makes a header for these cars with a Clevor, takes some doing on the valvetrain etc... It's not really an economically viable option anymore with so many good SBF heads on the market.

 

They are 5.0 heads. . On cobra and explorers and mountaineer i believe.. the only 351 that I'm aware that came with gt40s was the lightning. . But it used 1/2" bolt holes..

 

The gt used E7s. Junk. . The gt40Ps are said to be better but require special headers..

 

Better than the GT, near as makes no difference flow the same as a Cobra intake though.
