Can our stock camshaft be reground?
 

Wasnt sure of the material our stockers were made of so i thought i would ask. I thought futural was doing this at one time. I have had cams for my bbc reground before so i though this would be a cheap alternative to a new one.

Thanks
Phil

I've seen a cam from a 4.8 liter truck that was reground to be the same specs as some Lunati grind. It was done by a company called "cam in motion" or something similar I think.

I know with old flat tappet hydraulics, some companies would weld and regrind to different specs. That is possible because a flat tappet wears down to match the lifter, but roller cams are steel (hardened) and this is not the case. You don't want it to be welded (to add material), it could become soft. I personally have never gone down that road. Be aware that when you regrind a cam, sometimes the grinder will have to reduce the base circle to get the extra lift you want. You will only be able to change ICL and LSA by a factional amount (if any). I'd say it is still better to buy a cam that was ground at first to the specs you are after, rather than try to regrind a cam to a "bigger" one. IMHO, it is very risky (depending on who doe sit).

Ghetto.

Save yourself the time, hassle, and money. Just buy the cam you really want.

Like the others said get the cam you want and skip the regrinds.

Read up on Comp Cams website about regrinding. It's not possible to tell how deep the surface hardening is so it's possible to destroy the surface hardening doing the regrinding. If you get into the softer material below the cam is pretty much ruined. If the material fails and the cam self destructs you can be pretty sure it's not going to do the engine any good. For an idea there were a few hot cams that weren't treated properly and they didn't last very long, this was a few years back. The same idea applies.

My 72 Vette got it's stock cam reground when the prior owner rebuilt the engine. Year later I had a more powerful Isky Mega cam (new not a regrind)swapped in. Always been glad I got rid of that regrind.

BUT they do know pretty closely what the heat treat thicknesses are.
Regrinds also need longer pushrods, or some other way to compensate.
I've been speccing regrinds for Mustang V6's for years, and very successfully
I might add. It depends on the grind and setup. That is all we have available
for the Mustang V6 (untill recently) so we used them.

For an LS series engine, get the NEW cam, but custom specs
by a trusted tuner that specializes in these engines are probably
much better. We just use regrinds cuz we have to!

WHOA you dug this bitch up from the dead.
