Quicker than that same car with absolutely "as cast" ports, on otherwise identical heads, is my guess.
So, are you saying that the heads on her engine have absolutely "as cast" ports ? Hey, I'm asking. I don't know. There's no possible way I could know.
It's just my thinkin that these 1st gen Pontiac Stockers couldn't run low 10's with D-port heads, which have untouched, "as cast" ports.
Don't it take around 500hp or more to run these times/speeds ? Will a legal '67 Pontiac 400 Stocker engine make 500hp ? More ? How much ?
To me, these are legitimate questions. I don't have a clue how to calculate the answers. But, I assume that some here can.
