Are you talking about 894 X and 915 J 2.02?

Yes sir, thats exactly what I'm speaking of. Man, youre reading me like a book ! LOL

more intake runner volume, more power... period

That thinking might be true for brand X heads but the chryslers like velocity not so much as volume. port speed is crucial. ask GTX john. Bigger cc.s does not always mean better. I am currently working with heads that are WAY under spec and they are making alot of good power. Right John?

If your talking Super Stock, velocity yes. Stock, no - stock intake -stock runner- more volume more power... been there

I don't have a current National Dragster, are the port volumes published anywhere else? What are the volumes for the 894 and the 915? I assume the 894 has the larger volume?

Bub, may I ask why you feel intake volume is more important in a stock vs. SS engine?
