You have good heads and a big cam for a stock stroke engine so I wouldn't be surprised that it is still pulling at 7000 rpm. Most strokers lay over well before then, even with MW heads.

We have a low deck 512 street engine on the dyno today. It is all done at 5500 rpm but it makes 600 ft-lbs of torque! Going in a Dart, the owner will be happy the first time he stomps on the pedal!
