what is you end goal with the car? with heads, cam, stall (about 3600), 3.91 gears, suspension mod, and a set of radials (and a tune to match of course) you will be running 11's all day...with the right driver it has been known to touch top of 10's. but im sure your not looking for that aggressive right lol? right? if your looking to bring it alive 3.73 will do it but those 3.91 will help trap better numbers with a slightly higher RPM drive...just dont expect to much top speed with 3.91 gears, maybe around 165mph with that build...but you will get there fast
