8BA cam position

[Bored&Stroked]

I don't necessarily believe it has slid back. About the ONLY way that can happen is for the front flange of the cam to wear excessively and/or the front of the block to be worn off (the thrust face for the cam). If never seen either happen, though I have seen a case where the cam bolts were too long and ground into the thrust surface a bit.

Did you happen to use repop cam bolts or a repop cam-bolt-locking plate (which are sometimes thinner).

Also, if anything like the above happened - enough for the cam to move, then there would be some obvious metal in the oil pan - a LOT. I'd check that out.

Also, I noticed the cam lobe in the picture appears in about the right place on the lifter.

Probably chasing a ghost at this point in time.

I didn't rebuild the motor. The previous owner Gerry Groswold is deceased and had the car for 30 years. I've had for 9 years I'm not sure when it was rebuilt.


I didn't see and metal in the oil and it was fresh. I'll look at it again.


The cam lope is not exactly center in the lifter. Maybe it's been like this from the beginning.



To me the cam should be center in the bearing.
