I can't say enough about SD, Dave has spent a tonne of time helping me out and giving me great advice, which has helped me work my car down to low 12's (12.22 @ 113.3 MPH) at 3500 feet.

Performance update, with the new Edelbrock heads installed the 65 has now run 11.71 @ 119.4mph and still running the stock Tripower!!
