Anybody go from performer to an rpm air gap

Stock heads, .050 down the hole flat tops probably talking 8.75:1-9:1 comp. Coupled with a 284 duration cam, 3800 stall verter, deep gears, and a 3400# car. That combination should run easily on pump premium, if the tune is decent to good.

Make sure that your front suspension has at least 5" of travel or more. Adjust the front ride height as low as you can live with and cut down the upper control arm snubbers to about 3/8" thick. This will give you good front end travel. The more front end travel you have, the less the car will want to unload the rear suspension on the hit.
