Reground Cams

[docrobot]

I have heard the term "Regrind my Cams" and I am confused.

If you do in fact grind down a Cam, would that not reduce the lift of the Cam? Would that not reduce torque and horsepower?

What am I missing?

That just means they take your stock cams and regrind them to change life/duration, etc. It's not as strong. What you want is a cam which is grounded from a new OEM Billet. Reground cams are just cheaper, you pay for labour and not material cost.

Basically they grind off the material opposite of the top of the lobe that's what raise's the lift and then the change the angle shape to change the duration.
It's a bit simplified.You really should make sure that you get cam from a reputable regrinder because most cam's don't have much material to be reground so your are limited to the types of perfomance grinds.
For me it is a lot of work to change cams so I think you might be better off buying a grind"new cam" that suits you then to save a little money to buy a reground cam that isn't what you are looking for.Well that is my own opinion.
