Major cam problems!!!!

Jack do you know what valve springs are on it ? I know there arent to may choices for magnum heads wich is going to be a problem. The stock springs arent good for much over .450" lift. The other chpice are the Mopar Perf. race springs that came on crate motors and over the counter Magnum heads. They're good for around 550" I think.

If you go with a Hyd roller you'll need to find some AMC style push rod oiling roller lifters and you'll need a retro fit kit. Comp Cams and Crane sell retro fit kits and they probably use a push rod oiling lifter. Just ask and make sure. A roller cam will cost you around $300 and lifter will be around the same. You'll probably need a shorter push rod too.

If you go with a solid roller you'll need adjustable rocker arms wich would be a bad idea with any cam over .500" lift. You'll also need a bronze oil pump drive. You'll be over $1000 for a solid roller set up.

The other choice is a set of Shubuck lifters wich are reusable you'll never have to buy a set again even if you change cams. They're around $600. Overkill for your engine but probably the cheapest way of the 3.

I would talk to some one who really knows Mopars and valvetrains. Talk to Ryan Johnson at http://www.shadydellspeedshop.com/ or Scott Brown at http://www.straightline-perf.com/ about a cam/lifters/springs and your problem and see what they say.
