I was thinking the same, add in the lack of vacuum advance and mech secondaries too. I tuned mine way down to make it streetable and have functional power brakes.GaPonyFarm said:
Yup, I was thinking 525fwhp, you'd be pretty lucky to put down 475 with that (assuming our guesses are right).GaPonyFarm said:

thanks guys, my converter will stall from 2800 to where ever my power curve is, special JPT 10'' converter, jim says when you mash the pedal look out, my engine guy seems to think 475hp, but who cares i need torque down low from light to light, not worried about 6000 rpms unless i race it once in a while, street car and little race, 500ft lbs is a lot of torque man this thing going to brake something i have a feeling, cant wait to fire it up soon. thanks, what gears should i run on this thing, 3.50 posi now.
