12 second 340

Thats a pretty stout cam. Does it not have a lope at idle? What rpm does it idle at? The guy i bought my dart off had the 3.91s in it and said he had to shift into second in the middle of the intersection...This from a stop light or stop sign. So put the 3.55s back in. Mind you he was almost as old as me. :drunken: ....Sometime though take those heads off and see whats in there. Take care of that puppy and finger the ricers. :thefinge:
