I have a 468 Chevy motor in my 67 Chevelle. This winter I took the motor out of the car to fix an oil pan gasket leak. While I had the pan off, I checked the main bearings and decided to replace them. I also replaced the rod bearings. The camshaft and the lifters were replaced less then 4000 miles ago. I miked the lobes of the cam and they were all within a couple of thousand of each other. I reused this cam and the lifters.

I tested the old valve springs and found that they had 70 pounds when closed. The cam requires 144 pounds when closed. I replaced the springs with a set of Comp cams beehive springs, 26120-16 The cam was a Crane cam 134781. solid lift .567 intake .590 exhaust 314 duration.

Since the was a used cam, I did not think to use a break in start up. I did coat the cam and lifters with Lucas Oil stabilizer. I did prime the motor and used Valvoline 10w30 nsl oil in the motor.

In less then 200 miles, I started to wipe a lobe off the cam.

Did the new, heavy, spring pressure without moly lube and a proper start up kill this cam? Should I pull the motor out and do a total dissemble and clean the insides?
Or can I replace the cam and lifters, change the oil and filter and hope for the best?

Thank You
