My advice is Call Hughes engines, give them all the specs on the car and motor. They are well versed on Mopars.

That is what I did.They have the best tech advise.Make sure you tell them what your doing with the car{street/race} or both.This is the cam they recommended.
Flat Tappet Hydraulic / Three Bolt Timing Gear. Use where rules demand a hydraulic camshaft. 3800rpm stall. 4.56:1 gear, large single plane or 2x4 intake. Stage II or Stage III HP ported heads. 200psi suggested cylinder pressure. Street/Strip for stroker engines.

When you get to a stroke that large, if you want to make some power, you need a cam that will feed it. The ususal "050/512" I'd look at is .550-.600 lift (with 1.5s), and around 250° @ .050. If you have power brakes, take 15° off the .050 figure. If you have smallish heads (stock RPMs or any factory iron heads) you may want more lift and duration. I would also not run a hydraulic. You want the solid flat tappet.
