DON’T BE FOOLED!

That Dart( Fink’s car) I am sure was making WAY north of 1500 horse to the tire with the B1BA heads on it.
1000 horse isn’t much these days. Literally junkyard stock LS stuff with a Chinese turbo is making power like that
That said, I agree with you. Just saying 99.xx% of people with a turbo deal can go way faster than they could dream of, even with non killer heads.
Yea but that’s why junkyard LSs with a turbo make the power they do. The heads are basically factory race heads. Same with gen3 hemi stuff.
Ask your buddy if he’d trade off his B1BA heads for a set of X heads and see what he says. Tell him it won’t matter because he has boost and see what he says.
