Hi Tim, I agree 100% about the "look", but if you're looking for all-out power Turbo is (most likely) the way to go? (In my neighborhood here we have 4-bangers making over 800, some even at the tires, google Vinny 10 racing)!)

Hi kev, can't have your cake and eat it too, if you want "ultimate" HP you'll have to deal with the heat!

If I was going to look to set any legitimate records today with the Flathead ( I'm not, believe me) I would most likely run it "Turboed", injected, and possibly on E-85, if not, on race fuel for sure! Definitely would be walking in "blind" though on a build like this. I would assume it would have to be a "concreted" block, at least partially anyway!

Thanks, Gary in N.Y.

P.S. While I have some peoples attention here I just got a phone call from a good friend and was told to expect to see a 25% increase in ALL off-shore cranks. After he hung up I made my own call to one of the larger mfr's and confirmed his info, it IS correct. This will affect the Flathead cranks and, I suppose, all the off-shore conn rods also! If you're contemplating a stroker in the near future you may want to pick up the crank/rods now and "stash" them??
