you cannot use a predator head,, and you cannot use a millenium head or any stage v head for that matter

if you want to run ss/am, or a/sma,, you need to run parts with numbers from mopar

a/sm and ss/am stuff that are fast are small blocks,, but i dont think you can get there with a small block without alot of money,,, the p-5 hemi is dead since there are no "new" available head castings

your best bet is to get a hemi 99 and destroke it some,, run it like that then build a new one with a small bore,, and build a 420 inch motor or so

if youre serious about this i may build one over fall/winter,, i can share ideas with you if you are doing one too

lloyd wofford has a b/sma stratus that has a patterson 358 p-5 hemi in it,, it make 950 or so and runs about .45 under,,, since there are no parts available to build a "better" motor,, there are thoughts to build a hemi 99 around 400 inches for it,, and move to a/sma

Jeff I was worried about that cause I know that NHRA specifies approved heads but I forgot about the fact that it must be an OEM released cylinder head. That really puts quite a downer on my plans. We have tons of spare 400 parts and things but no hemi 99 stuff whatsoever. I am serious when I say I want to build SS/AM car and transition it towards A/SMA, I just don't know if it will be a big block anymore. On the other hand, the technology should advance quite a bit before I get the chance to build it. Like I said, this is research and learning for me. I have to get my degrees first and the knowledge of engine building I will have leaving grad school will be much more significant then, alotting me a little more opportunity to do more building than paying to build hopefully.
