have camshaft reground? What about re-hardening?

[theKbStockpiler]

Changing the gear is not the problem ,getting a different sizes gear is.
I think isky cams come without the gear and or there are other ways to put your own gear on. As I'm told ,most people are just using the 'one size fits all' and not worrying about it. It seems that using a reground cam is not worth it. It throws off the geometry of your valve train. Non hardened low cost cams work harden themselves against the lifters when you are breaking in the cam at 2000 rpms when new.

I'd use a new one, and just check the backlash while you are building the engine.

New gears are Alum.

Stock gears are magnesium alloy. (like the case)

I've heard good things about these guys.

Ok, I'm rebuiliding the stock AE-series dual-port 1600 engine in my 1972 Super.

The valves had been going out of adjustment in the direction that the camshaft was wearing. The lifters were flat; the camshaft has discoloration, and the exhaust lobes were slightly smaller (measured by micrometer) than the intake valves. I have new lifters; I don't think the camshaft is re-usable the way it is.

Can I have the camshaft reground? I have a grinding shop that re-did the crankshaft that I trust. I'm sure the wear has removed some of the surface hardening; the grinding removes more, I assume. Can that be re-applied? I don't want to get a correctly-ground camshaft that then shortens the life of the rest of the engine by wearing very fast.

I'd just buy a new camshaft......but I don't see ANYWHERE that sells camshafts any more that allows you to set the gear size. (Mine is -1). I'm suspicious of the camshafts that are sold without any gear number, particularly the ones that look like the gear is Aluminum (stock are steel, right?).

Anyway, any input would be appreciated. Thanks!
