What particular class are you thinking about?

I don't think anyone has attempted it. Any of the larger cube XR2 or Ernie Elliot block based P7 deals I have seen have been power adder combinations. I am in Australia, so I wouldn't see any where near the cars you guys would.

The Ritter blocks were designed primarily for the P7 head, the wedge head option was made to work with the casting. Either way, they come in 9.6" or decked down to 9.2"

As has been mentioned, Slawko and CFE have programs for the P7 head, where they shift the intake valve etc. I think any decent shop with experience in SB2.2 heads would be able to tackle a set of P7s. They won't out perform a P5 head.

A W8 engine can make over 1000 with a single 4 barrel intake, the P7 is a better head IMO

It would most likely be a Econo Altered or possibly Econo Dragster, a full-chassis type car that is easier to work on.

Comp Eliminator is one of the few areas in Drag Racing left that is still innovative. It takes a certain type of person to race in the class.

The red Vette sees that RPM, these days those little engine like those of Warter 10,500 is on the short side. Ours is 400" and sees that RPM. Still hang around alot of comp stuff and most of the fast smallish stuff is 11,000+

Al, if you don't mind. Could you detail the ?525"? ?B1 MC? that you ran last in the Cuda? What kinda RPM and cam? Of course, that was a respectable piece considering the parts used.
