Johnta1 and others :

The 500/504 cam was custom ground for us at Comp.
Lobe #s are 5214 int./5217 ex. On a late version we used the 5210 ex. lobe for .525 lift. These are based on the Magnum series of lobes.
No info in my files for other profiles used for the HC-03/63. The cam doctor report is for the 500/504 cam. was measured on 4-16- 1990
