Hmmmm lets see......i had it about three years this Nov. We got it mostly restored..but did some mods since we've gotten it. It's a 318 slap stick auto, thinkin it's a 904 tranny....don't remember?? 373 sure grip rear. We put glass pack mufflers on it, moved the pipes from rear to side. Cleaned and detailed engine comp. New gas cap, chin spoilers, Wheels and tires, new gas tank, little things like that.....had it down at Atco and it runs 14.4! AND YES I ran it down the track.
