Engine is Not the ONLY make car go faster!!
suspension, exhaust system ,and aerodynamic and lighter body make huge deference, my friend.
P.S. since Phil used Slicks on the rear , He should use drag wheels (15X3.5) in front,
this could lower his ET .3 - .4 sec.
he have his reason why he did not!
when i was darg racing, i used cheap spare wheel in front.
and won 5 champions with my Supercharged 86 vette ,what a trick!!
