Duster 11sec?

Are the heads ported? I don't recall what the B1 heads flow in stock form, but I seem to remember that it was not anything spectacular (probably about the same as stock Edelbrocks and such)...if that is the case, then I would only expect high to mid 11's at best. If you fully port those heads knock another second off that number.

Something to check, make sure you have the timing set correctly, this will make or break it (my car likes 34°). Also, don't baby it too long.....When I built my 408, I broke in the cam for 20 min, drove to the gas station (about 1 mile away), got fuel, drove home with a heavy foot and then went to the race track to beat on it....did this with my previous engines as well, no issues.
