Warrior Racing cam info needed
Going through some of my old stash and found a Warrior Racing cam #744. While this can be assumed to be the RA 3 cam, but does anyone have specs on this particular cam?
Any info on who made their cams? Stampings on end: E909P (which is an Elign number ) 9Z001 RA3 cam: ( 9785744 301 313 224 236 .410 .410 119) Elign 909 specs with specs of: Part Number: E-909-P Camshaft/Lifter Specifications: Cam Lift Valve Lift Adv.

.407" is the 'standard' Pontiac valve lift number
All the normal 389s, 400s, and 455s had basically that lift. Slightly differing durations depending on the application, but .407" lift across the board
As far as the Ram Air versions camshafts, I think only the RAII (.470") and RAIV (.520") had more valve lift. They used the same 9794041 camshaft in both RAII and RAIV, but the IV used 1.65 rockers to achieve the higher lift. |

That looks like a Melling duplicate of the Pontiac 9785744 (Ram Air III) cam. Anyone could buy one back in the day and H-O Racing sold them as "Exact Duplicates of Pontiac Ram Air Series", H-O #HC-56.
H-O also sold a High Lift version with same advertised duration, but lift of 0.465 (I) & 0.469 (E) with 1.5:1 rockers made by Crane Cams under private label. It was H-O #HC-02 and was very popular, IIRC. |

At the time that Craig, Kern, and Ken were running HO Racing, Crane Cams purchased several smaller camshaft companies and one large "Production Camshaft" company.
They bought "Wolverine Camshafts (Jackson Michigan) and Universal Camshafts in Muskegon Michigan. They also bought a "production camshaft company" "CAMSHAFT MACHINE COMPANY in Jackson Michigan and made Don Hubbard (Camshaft Guru) the big boss. He was one of Harvey Crane's "Guys" as was Harold Brookshire. Glenn Corwin (a Pontiac Engine type guy) was his Technical Expert. RA-II F-Bird Guy. So Glenn used to tell me who CMC sold all of their camshaft to and where they came from. Mr Iskenderian had a cartoon one time in Hot Rod showing a dump truck "unloading (dumping) lots of camshaft behind another "camshaft company". The point was Ed was saying that very few typical camshafts are actually made by "the company selling the camshafts". Roller Camshafts (in the old days-YES). Production type grind hydraulic camshafts - NO. I saw CMC grind a 744 camshaft on a production machine in under one minute and it was dead on specs when checked on the profile machine. Would not surprise me, Craig, if Glenn Corwin did not "watch over" the orders for your HC-02 camshafts. But back on the Warrior Deal, all Warrior did was rebox the camshaft that they bought from a wholesale warehouse in Detroit who bought it from Crane/CMC. Unless Ray or Dale dropped it it should be a good camshaft. Tom V.
