340 Cam Change - Lunati vs. Comp.

You can run the 60403, but pay close attention to the retainer to guide clearance. Its pretty easy to measure. Remove the spring, reinstall the lock and retainer and see how much room you have.

You can run stock rockers, but the question is how long will they last? I have seen it, along with many others here, where the pushrod goes right thru the stock rockers with these type of cams.

SO you know the risk with the rockers, its up to you if you want to take it. The old X heads are not to bad and I think it will perform well with this Voodoo cam.
