Thanks for the input.

Bruce,

No, I wasn't confusing MFI w/ CIS - however you did tell me something I was not aware of - that the "T" stacks don't have the wall thickness of the "E" and "S".

Looks like I'm in the market for some new stacks...

Tom,
I agree, the 9.5 on pump gas would be a bit sporty.
Maybe what I should aim for is a 911/42 - 75S 2.7 spec. engine; 8.5:1 - 175HP - 175 lb/ft @ 4K.

That would mean new Crank and boring the spigot bores.

I think I'm gonna here that that the 2.4 case wont handle it...
