seems to me the engine you have probably wouldn't perform much better than what he has..... although the potential is there with the heads. Mph/et I'm assuming is from the basement you live in (florida). Not going to get nines in the OP's car with that. I've lost count how many times we've kicked our 360 to the curb.... just to end up dragging it back out as one of our "fast" builds gives us grief. We tried to sell it on two different occasions from carb to output shaft of the trans.... nice 904, converter that works good with the combo for $2500 and nothing but tire kickers.
