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

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.

Great information Maddart and thanks for the response. Generally tighter lobe centers will make the make the power delivery peakier but it won't hold out as long on the top end. I figured this in plus the cast iron heads and took off 8 degrees of duration since this is a solid lifter cam and that's how I came up with my output characteristics. Apparently there's enough port flow that this is not an issue and Brian did a stellar job on those heads. :read2:

Let us know how does at the strip or a chassis dyno is there is one in your area.
