Cams - The Pros And Cons Of A Regrind Vs Billet

[SirRacer]

I was discussing this with a mate the other day and i honestly dont know the pro's and cons of a reground cam.

Would anyone like to enlighten me?

Reground cams have a reduced base circle to increase lift. this means if you have solid lifters you have to shim them to get your clearances right. also they can have excessive ramp rates which will put higher strain on valves and springs.

Billet cams are stronger. reground stock cams often have addtional material welded on introducing further weakness.
