657 HP with a 509 cam? Not by me!

Second line in my sig!
A crummy chassis, bad tires, bloated car weight, etc.... Will kill track times. No matter how powerful the power plant is.

Excellent chassis, good tires, light weight car, etc.... Will allow a lowly powered engine to shine like a star. An old member here (not any more though) had a 360 Duster with a small Crane 216/224-.454/.480 running low 12's high 11's. Not bad for a low comp pump swill machine.
