Although I never really liked 66-67 Chargers, I have really liked this one for years! Which motor are you using? Generally, what are the rules for this class?
The stick class is RWYB no tire limitation. We have the Cab B1 572 ready to dyno, a 499" -13 engine ready to assemble (your old heads and t-ram) and I'm picking up a mystery Indy headed engine on Saturday.
There are cars in the class well into the 5's so it's pretty darn competitive.
