Well, the low dollar 360 i put in the Shelby is out....
One lifter has a hole in the wrong end. 4 more are all concave in and about to have an unwanted hole..... Camshaft is toast.
This was a good used cam and a set of new Sealed Power lifters 3 years ago.
Not enough zinc in the Rotella-T, or poor quality lifters? Or both?
