The W9's might be overkill (or budget kill) for me. What can you get out of a set of ported W2's on a pump gas 408? I've got 11 cars, so I have to kind of spread the funds out a little. The Dart's current 360 has pushed it to a 13.42 @ 100 mph best, but it's pretty tired now, hence the R-block purchase. I'd like to get it in the low 10's so I'd have a chance at qualifying for Street Machine Eliminator if I went for that class.
