***MADDART's 70 Dart Video***

I would think that with that combo you'd shift in the 6k range maybe 6200? Let us know... Did Brian at Imm say that these heads were ported to take advantage of the lift?

With that LSA it should have massive mid range torque (3-4.8K) but drop off hard in hp beyond 6k.

Well when driving the car on the street I cant tell that it drops off above 6200 Rpm at all. It actually pulls hard all the way into the 7k range. I shift it between 6500-6800rpm most of the time, but like stated in the Video I have not ran it at the track as of yet. In the Video I was shifting it at around 5800-6000rpm, there is a lot more in it. I used all forged internals 4340 Crank, SRP Forged Pistons,H Beam Rods, Girdle with studs on the bottom end, head studs etc. My original plan was to SMACK it with a 200 Shot and I still might I would probably up the shift point by 500-800rpm and see if it will live with the JUICE!!!!

As far as the port job goes, these were probably one of the first set of RHS/INDY heads that were ported. Well with BJR's screw up on my first set, probably the 2nd set.

I have another set of the same heads done by Brian at IMM, same springs etc on a 318/402 Stroker that are not ported assembled on my engine stand right now. It will be installed in my 67 Dart GT hopefully in a few months.
