    Default 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 or 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.
