This is not an all out how much power can I squeeze out of an engine type build. I did not do a lot of work on the heads, just a good valve job and a mild port clean up. The cam is pretty small and the drivability will be very nice. I think it has great torque down low considering that the 383 has no stroke, 3.38". Yes there is a lot left in this combo. Spend about 40hrs on the heads and it will go over 500HP, but that wasn't the point here. I wanted a mild 383 that you can drive anywhere, anytime.
BTW a stock HP 383 was rated at 335HP GROSS with 10 to 1 compression. This one is making 100HP more than that with less compression and the same drivability.
