I had some concerns about suspension, braking, and heating in my F-150. The guys at performance authority got me in quick and kept the price well within reason. Highly recommend.

I have had Performance Authority work on my 56 Bel Air. The car came with an 305 that was rather weak. I had the guys at PA do an engine swap with a 383 Stroker. I highly recommend Performance Authority to anyone looking to have work done on their vehicle.
