That's just a regrind of the W-31 cam.

You're right, I didn't look at that, I went straight to the specs.
Those are clearly the Olds lobes. I have access to the Pontiac Ram Air III and IV lobes as well and they're different that those.

I run the 280h which is suppoused to be a modern grind of the w30 w31 cam. Works good idles at 850 rpm . The only thing about this cam is using power brakes you only get about 2 pumps and vacuum is gone but i have never had an issue.

was reading how if you use a e vac system you can t of it and have power brakes to spare
.

coppercutlass

yeah i was actually reading up on that . Im gonna try the vacuum canister i made . I never used it but im gonna have to. i really dont want to go to manual brakes. I was trying to find a used moroso vacuum pump but they are expensive.

The cam is great for a restoration. However, I would use a modern grind.

Can i use it as an option to build my 455 with the w30 specs???

Run to Rund

The 68 H/O used that cam if non-AC. Stick 70 W30s used the bigger 328 degree, and automatics used a smaller cam than the 308 deg. So, it would not be "correct" for most 455 restorations, although it is a decent cam even today. 66-7 W30s used a different part number 308 deg. cam but it was virtually the same.

let me alert you that the 455 going into my T/A

What are the rest of the 455 specs?

oldsy

I was thinking of advanacing the cam and keeping the motor stock.So the specs would be stock.On the heads im going to shave them and do a port match with the intake and a port them.
