Since no one has mentioned it yet, what about using pump E85 for fuel to run a higher compression? Is it available in your area? I would think that 800 naturally aspirated hp would be easier to reach with a compression ratio over 12 to 1.



That's what I would like to do but it's not available any where near me.



Cab, I already have these parts KB aluminum block 4.375, Callies 4.5 crank, 7.0 Oliver rods. I also have a Comp roller .727/.706 283/296 and a custom 1250 Dominator. To lower the compression I'll need to get another set of pistons, the ones I have put it at 13 to 1.

I need to get heads and an intake but would prefer something besides Indy. In another post I saw where someone was getting 405 cfm from cnc ported Victors. Maybe B1's would be a better choice?



Shoot for about 11.2-1 and I think the ported victors and the rest of your parts will get it done.
