Is this possible stock crossfire 13's?

I did a pretty thorough job of porting. No metal added. It runs high 13s, now. What will it run with the magic manifold?

RACE ON!!!

Just porting the intake and a crossfire will run 13's? I found this on another forum?

Who is calling BS?

Is it or :L or otfl or ???????????

Looks like you found CFI-EFI at the CF. I think there is more to it than just that. There is NO WAY a stock CFI will hit 13s, IMHO.

If you do some further reading, you find your answer as to what else was modified. I think his point is he has not gone inside the short block.

I read on another forum that he runs mid to high 14's and he says at sea level it will run 13.8. I don't know if he drove to the coast and pulled a 13.8 or maybe he is just doing a calculation and coming up with that. Someone that goes to the same raceway posted that he does mid to high 14's. So I guess that answers my question.
