I am cunfused, you are going to replace a 351W with a 351C? I like the Cleveland and I am rebuilding one now but that is what came in my car. If it came with a Windsor I would have rebuilt that. I have a 429 CJ with no home and I thought about dropping that in my 73, but figured it would just be easier to keep the 351. Everyone is talking about big horsepower, is that what you want? Is your Windsor a 69? Those are supposed to be the best ones.

Do what you want, it is your car. I think either one would work well.

 

yeah i am going to replace my 351w fora cleve neither came with my car, when i bought my car it had a 302 and that wasnt even the original 302, so at this point im not worried about what was the original engine i am just wanting to get some power, my goal is around 400-410hp thats where i would like to end up when the rebuild is complete...

if i went with those CHI heads would i be better goin with the 2v or 3v heads what whats the difference ??

 

the 3v is a hybrid mix of the 2v and the 4v

 

yup, the 3v's seem to be the best from everything i have read on them (for streetable motors)

Parker makes some neat stuff for the Cleveland. If I was going to run 4V heads I would use their intake and tongues to change the intake port.

Clevelands and Clevors are apparently black magic

so i would be better off going with the 3v heads from CHI?

 

With the CHI 2V heads you can run any 2V intake you wish to.

With the CHI 3V heads you must run their intake manifold, also the 3V heads are available with three different intake runner sizes. You can go as nutty as you want to, the shop that built up my 377" 2V also built up a drag motor for a fellow in Redding, CA with 3V heads. They were expecting about 650+ horse.

You will probably spend about$3,000 on heads and intake if you go with the CHI setup.

The Parker 4V intake is only $450 + $100 for the tongues. Then all you need to do is find a good set of 4V iron heads to rebuild, should be about half the price of going with the CHI setup. Might be something to consider.
