Would you run this cam?

I have a roller cam to go in my Mark IV 454. (Step nosed style). It has what look to be some nicks, as well as a groove halfway around one bearing journal. Would you run this cam or get a different one?

No car yet; currently looking for 66-69 project/driver.

Looks like it was used for a setup. Just make sure there are no real high and low spots on the lobes and just run scotch-brite on the journals. as long as the cam is not bent or binds up it should be ok.

On the journal Iíd use crocus cloth in long strips such that you can shine it like you would a shoe. Pulling down from side to side over the spot so that the scratching happens in the direction of spin only. The material comes in small spools.

Re: Would you run this cam?

Small pits are fine on the journal as long as they are not sticking up.
The lobes look to be parkerized.

I would not run it until i found out what is up with the black color.
I would probably regrind it to something else and know what I had then.

Take a cloth and some lacquer thinner to it and see if the black comes off. Or carb cleaner.

Re: Would you run this cam?

Was told by the cam company that the black is parkerizing and to run it as is. They also said the little imperfections are fine to run.

Re: Would you run this cam?

I have never seen a roller cam that has been parkerized. Guessing this is a SADI cast iron core and its to prevent rust.

Is the SADI cast iron core good or do I want something else?

Re: Would you run this cam?

Ok, no pro here, but you HAVE TO RUN anemic valve springs with a cast core roller; so you've limited the RPMs to maybe 52-5500 TOPS, and DO NOT want to make big power; if correct, then its fine. Me personally, I'd would NEVER run a cast core roller unless it was a old wood truck or something, for free. Rollers = used to be race car stuff = BILLET cores only.

Yet again, you keep it mildly "sprung" and under 5500, it SHOULD be ok.

All that is agin' my "religion" ; I hate losing HP when I rpm. ( my new BBC is limited to 6300 BUT, the springs with 400+ open psi will keep the roller lifters VERY stable thru 6500+.In fact, the builder has run the same setup thru the traps at near 7000 rpm. Billet with a decent spring. )

It must be a COMP cam yes? The only folks I know that "half-ass" their rollers. But they will work, only gently and DON'T rev that thing; it WILL float with their recommended springs.


PS just an FYI, many folks here run the GM HO502 "takeout" cam in their 454's. Actually "fits" really well! I might prefer the ClaySmith "oem head" BBC roller, but it will cost more. I use a tried and true ISKY cam. Costs more yet.

This is what a roller cm ought look like..... I mean BLACK IS BEAUTIFUL! ...... for flat tappets, not rollers.....

Re: Would you run this cam?

This cam is advertised as a much higher rpm cam than that, with 350# open spring pressure and 150# ish closed pressure. It is not a comp cam.

Re: Would you run this cam?

Ben I ran 370 OPEN AND 135 CLOSED with a solid flat tappet designed to turn 7500 w/o issue in the L88. Those pressures wont hit 6K reliably with a uber heavy ass hydraulic roller BUT........

as I am NOT a pro, I prefer someone who is chime in and correct me.... I'd hate to steer you wrong.

Ben, what are the cam specs and in regards to the springs, is that what the cam mfg. recommended? those specs are good for a mild hyd. roller,about close to what a ZZ502 cam would be.
