Anyone have any experience with the Trick flow power port 270? Any idea what kind of power can be made with them? Looks like they flow better then the Indy EZ? I would guess my combo now is somewhere around 650 HP at the flywheel. I cant see spending a bunch on new heads to gain 20 HP. I would like to be in the 750 to 800 range but would assume I need to go to a ported 440-1 to get there.
