Cliff Ruggles:
Far as I know all the "generic" grinds are from CMC (Camshaft Machine Company).  They are in Michigan, Lansing maybe?

I called them recently inquiring about getting some WG-5059 cams done, but gave up on the idea.

The Summit cams are excellent, look at the first numbers (advertised). 

The big 454 will LOVE a long duration cam on a wide LSA.  I'd look for longer seat to seat timing (advertised duration), up near 290-300 degrees seat to seat.  I use a 292/308 duration cam in my 455 Pontiac engine (hydraulic roller).  It has 11 to 1 compression and makes great power on 89 octane fuel.  No issues anyplace and it's a daily driven car, not a "race car" with mufflers.

We did a 454 back in 2001 at 10 to 1 compression with peanut port heads.  I re-worked the heads with 2.19/1.88" valves in them, and went with a 234/244/112 cam from Crower.  That engine ran for years in a good friends 69 Chevelle.  He drove it everywhere, and raced it just about every week.  It was a solid low 12 second car on DOT tires.

He's upgrading the engine this Winter with a 496 and aluminum heads, and big HR cam on a wide LSA!.....Cliff
