Anyway, to reply strictly to the quote above here, these numbers, 155 HP/265 TQ are indicative of what we almost always find on our basic 292" build, 3.312" x 4.250", Ross pistons/metric rings, Isky "8800", and single small 4 brl carb! Tri-power's see just a bit more!

There is NO porting, NO oversize valves, and NO hidden little "secrets", just some old-fashioned type excellent machine work! This is basically the identical build to my friend Ron's ride in my signature below here! Going above 40,000 trouble-free miles now coming up on 9 years!

Thanks, Gary in N.Y.

P.S. Haven't heard back from Joe yet with any input from H&H, expecting to hear soon though. On an added note, knowing what we've learned through the years here about the power available from Turbo's this is what I'd be researching/testing if I were "chasing" Flathead HP. The sole issue with blowers is they consume some HP to run themselves. Not so with turbo's, have never done one though as far as I know. Sometimes after we do all the machining for some customers they walk out with their pieces and I don't hear anymore! There may have been a Turbo or two installed, just not aware.

gary, my concern with turbocharging a flathead is the heat build up in the exhaust between the valve and the turbo. in a flathead all the heat is kept in the block....
