I was wondering the same thing about the poly being the daddy of the hemi, born 3 years later?

1.5 hp per cube at 402 CID = 600+ HP... is that even remotly possible with those heads? Never heard even the most optomistic of flow numbers getting anywhere close to enough air flow?

I am watching engine masters this year but it is just interesting and not much of a competetion as each class only has a handfull of participants. Looks like a couple of last years winning gen III hemis came back almost un changed and beat the other hemi in the challenge.
