Question

I have a 68 dodge dart with a 360 with 340 j heads with the mopar muscle car cam 429/444 lift and a m1 dual plane intake. It ran great until i collapsed a lifter two weeks ago. Having to remove the intake anyway i felt this a great time to upgrade the cam to a 484/484 mopar cam and install a 6pack also. It ran really great for about one day then flattened four cam lobes on the left bank.Thinking it a bad cam from mopar changed the cam again adding new push rods and rockers. This second cam lasted two days and did the same thing on the same lobes. I think it could be one of two possibilities-- piston to valve clearance or an oiling problem. Can anyone help with what may be going on and what i need to do to correct the problem? I really want a hotter cam than the muscle car regrind to go with the sixpack set up.

Make sure all your lifters spin freely in the bores
If they don't, it will quickly waste your cam lobes.

Check to make sure you don't have coil bind on the valve springs. Any time you increase cam lift you need to make sure the springs can handle the extra lift.
