the enginemasters 318 I have posted about on here many times( and raced) went 11.60’s at 3400 pounds on super stock springs, flat hood, etc, etc.
it had a much smaller flat tappet cam than it made 477 on the dyno with at enginemasters. 230@50 compared to 247 as dyno’ed
At 3000 pounds and going to a roller cam, I think it would have dipped into the 10’s fairly easily. I ran 4.10 gear. More gear and convertor would have helped too, but it was a dual purpose car.
