I think with the torque thrust 2s..you should be well over 500

J/k

I would say about 390ish

What should my trap speed be at an elevation of 3600 ft? Stock it ran a 13.8@102 with a 2.2 60 ft on street tires. I am running 315/35/17 Nitto Drags but haven't been able to go to the track.

415+rwhp id guess

241 castings with 2.02/1.60 valves. Ported by a shop in town. Did a nice job on them. I can't seem to find the flow sheet. If I do I'll post the before and after flow #'s.

Sounds about right if the flow #'s are correct on those heads.

Just get it dyno'd and take it to the track. That's the only way to find out the answers to your questions.
