Power for a slant

wheel or crank hp? 200 wheel would get you in the 13's and is streetable, but not anywhere near stock. That said my 68 gets 20mpg on the drive from Phx to Vegas which is all uphill.

but what it sounds like you would want is to rebuild the motor, mill the block say .100 to start and then see what the chamber volume comes to. I would shoot for like 9-9.3:1 static compression. Get a small reground cam from Oregon, i would say something like 210-220* .050 cam duration with MAX lift on a 110 LSA. That with a 2 or small 4 barrel swap, larger exh and edge converter would really wake that baby up. You can do enough head work lol... I would have new hardened exhaust seats installed with the stock exh valve, then install a 1.7-1.75 intake valve, everything blended and port matched.
