Camshaft Regrinding?

What can be changed/done when having a camshaft reground? I have a couple solid roller camshafts that are to large for my currently planned engine and was wondering if it would be cost effective or even possible to send them back and have them reground to a smaller lift/duration?

Yes it can be done, but their are limits in how much the specs can be changed. And you need to watch the hardness, some times you can go thru.

Like Dfree said.....there is limit to how much change a guy could make and keep the heat treat area. It'd matter also if you want to change the lsa too.

What are the lobe #s and lsa?

Is "re-heat treating" not done, or does that simply make it too expensive to be worthwhile?

Sometimes it could get to that point....regrind + heat treat and extra shipping could kill a deal.

You can call my brother Ken Heard @ Oregon Cam Grinding. 503-252-5505. He's been re-grinding cams for many years. He also races a big block Ford.

Bullet did one for me for 125$ i think it was.

One of the two cams I have is a very old crower that I had the card for I just have to find it again. The other I got with some other parts from a pulling truck engine. That cam is a Schneider Cam and I didn't get a card with it I measured it once but don't remember those specs

FE guys out here love Oregon Cams another west coast choice is Delta Cams in Tacoma they are some nice guys too.

Delta cams re ground my cam, in use for 3 years and no problems with it. Solid flat tappet from a hydraulic flat tappet.

The Schneider Cam is likely a cast core cam and already a regrind itself. I'd check for that before I used it again.

Cast iron cams are through hardened , not surface hardened like rollers. They do not need to be re heat treated.

The problem I see is that you are trying to go "smaller" with the cam and this can be tough to do on a regrind. Going larger with more lift is generally easier to do because in the regrinding you'll be taking material away from the base circle and not much at all from the flanks and nose. Even if you go through the heat treat on the base circle it won't cause any harm.
