Retrofit Hydraulic Roller Lifters 340

I have the Crane's also. I also had the cam base circle cut down. It looks good, but I'll know for sure this summer when I finally light the engine off.

You don't need to start the engine to know if you have an issue or not. Run the oil pump with a drill and turn the cam around with the lifters in place. If oil squirts up when the lifters come up you have a problem.
