Hell, I'll even take a story about how your bolt-on 370 outran a stock one. 30 whp seems like it should make a noticeable improvement in these times.
I'm not going to blow smoke up anyones arse, but I will say that my 1/4 mile time improved once the HFC's were installed, I'm a pretty consistent dragger, and I seen my best time of 13.5 stock improve to a 13.38/13.41, I think ZEliminator also had a huuuuge improvement from stock to full bolt ons, I believe he went from a low 13 to 12.8, thats insane.
