The engine builder who performed the machine work on my big block did not particularly care for Crane Cams. He suggested I use a Competiton Cam. He stated that he has seen excessive lobe wear after a season of racing on some of the motors he tore apart. I have my engine rebuilt to the L78 Specs. I know Competition Cams makes a cam that has the GM L78 grind specs which is a solid lifter cam, which is what I used. I can dig into my paperwork and get the part number if you would like, don't know it off the top of my head. This cam works very well in my motor!!
