Wow! sounds like fun. Mine is not track proven either but has about 2400 miles on the combo. I think it will run low 10s which I would be happy with for a full street car. I have a 65 Coronet that my 588 Hemi is going in and it should hopefully run Low to Mid 9s.
Well, my car is pretty sorted out. It ran mid 10's already with no problems and a 1.41 60ft and just works....Now with the big inch mill, its about as scary as you can be and keep it on the road....Wish I had a vid. Everything behind you disappears in an instant as you wrestle the steering for control. So when time is right meaning I feel we have fixed all the major issues, we will be up for some TNT and probably get kicked out cause its only legal to 10.0
