Need help on cam choices.

Hey all I have narrowed it down to two chioces for cams to go in the 350 im building. Either Compcams xtreme4x4 cam or Crane cams Truck power cam. I am going to be using a edelbrock performer manifold, rebuilt quadrajet. I am going to be using the engine for mostly mudding and trailriding with the occasional drive on the weekday. If any of you have any input on these cams or use them please reply with pros and cons of each. Oh yeah the engine is going to be going in my /forums/images/graemlins/k5.gif Thanks in advance, Derek

A lot of people run the Comp Cams 4x4 extreme cams - and most are happy with it (from what I've heard). However the numbers for the Crane cam sound pretty good. Here's what I'd do: give Comp Cams a call - tell them what you've got, and what you'd like it to do/what you're going to use it for. They'll suggest the right 4x4 extreme for what you want. And then...just flat out ask them about the Crane cam you're talking about. See if they'll give you any reason why to pick one over the other. Whatever you do, you should end up happy with the result - both sound like they'll be a big improvement over stock.

I'd be happy to run some stuff through Desktop Dyno for you, unfortunately I'll need more info about the cam than what most cam manufacturers offer. I need the Lobe Center Angle and the Intake centerline figures in addition to the intake and exhaust duration and lift.
