One trick to this application is using a profile designed for a. Given your rpm range I don't think that's the case. I prefer to see you use a single pattern cam, but if the exhaust is really an issue you can add 4 degrees to the exhaust side. If you go with 38 degrees of overlap, you get 254 degrees duration.

So I guess any cam that matches the stroker's displacement and helps it to breathe up to 3500-3800RPM would be swell. That's where the Jeep always fell on its face with the 4.0L - highway passing power. What I'm really hoping to get out of a stroker+cam combo is as much low end torque as possible, smooth strong idle, and highway passing power while pulling that small trailer. 2.5" Magnaflow exhaust from header collector back, high flow cat. ![]()
