The aluminum was cheaper than the price that I got from racingengines, so I went with that. Also, the 509 aluminum is putting out at least as much, if not more, than the 540 iron plus the weight savings so I went for that. Hopefully the BB Hotchkins front springs will not hold the motor too far up.
Mike, I can't wait until next summer man. I am ready to finish the darn thing now, but you are probably right, it will be 1 year from now. Unless if we get another winter like we had this year to motivate me to finish it sooner, so I can drive it when dry.
I am thinking about the 200 now, because it will be an easier swap, don't take as much HP to turn, don't have to change my driveshaft, and I like the 2.74 first gear ratio. Hope Bruce's tranny can take that torque, from what I have heard it can.
One concern is that with my 3.89 rear ratio and .68 overdrive, engine rpm at 60 mph with 28" tire will be 1950 rpm!! Am I missing something in my calculations, or does the formula that I am using assumes 0 tranny slip. How many RPM would the tranny slip add? I would like to be around 2300 rpm or so at 60 mph.
