Gosh Ron,

I haven't heard anybody mention fully grooved cranks since the '60s. The idea for doing so was to feed more oil continuously to the rod bearings in high rpm racing, the Trans Am Mustangs turned upwards of 8000 rpm. But the drawback was the fully grooved journals weakened the crank, DOH!

So the fully grooved crank gave way to cross drilled cranks. Or was it the other way around. I forget. By the '70s, the high rpm boys settled on fully grooved main bearings.

Good ol' Clevite 77 fully grooved main bearings are all that's needed for your Pantera, thus equipped your car will be "groovy" enough!

your groovy friend on the DTBB, George
