Good stuff but, not many intake manifold choices.

John who used to own CHI now owns CID and this is kind of a 351 Cleveland head design for a big block Chevrolet.

With those heads that well into the 600 cid size motor is what's needed to get some velocity into the 325 fpm range going.

Tell you the truth I am not impressed with 1088 hp unless it was being made at like 4000 rpm!
You can cut a man's tongue from his mouth, but that does not mean he’s a liar, it just shows that you fear the truth he might speak about you!

I don’t think that’s bad with a flat tappet cam on pump gas, maybe I’m a little behind on the times
