Gotcha...Well if you can get it down to 3750 with you in it mid 12's
shouldn't be too difficult. Some nice heads and a smart cam choice
will land you there squarely.

That calculator is generous...
Between my dyno #'s and my trap speed it shows I'm only loosing 16.8%
through the drive line.
My car is NOT that efficient.
With a TH400 & a 9" rear I thought it would be around up around 20-25% loss.
