how much horsepower from my 318?

Heres a Video of my 72' Dart 318 with just a 4bbl holley and dual exhaust from the manifolds. the rest is 2.76 gears and stock old 904 tranny..

From the single stock exhaust and carter 2bbl to the 4bbl Holley and 2 1/2" duals from the manifolds it increase my 0-60 time from 9.2 seconds to 7.1 seconds as seen in the After video. you could probably excpect the same or very close results. As for HP id say a 20hp increase or so to the wheels compared to stock.
