The advertised duration numbers are usually looking a little bigger than numbers taken at .050" lift.

Back then, there was no measuring at .050”. Last(?) 30yrs was .050 incorporated to even out the advertising field.

“Power pak” was 375hp/440 and 383 RR & Super Bee camshaft. Heads were the same. Differentiating from low power 440 on C bodies & Satellites/coronets of regular 383’s.

Power Pack is just the magnum cam, and carb.

Crane used the .050" way back in the early and mid '60's, and pretty sure they were the only ones. They actually started the. 050" thing. We didn't understand it but it was there.
