cam regrinding?

[vn_v6]

hi guys, i haave a gemini and want to get a cam regrind, but i was thinking, wont that make the lobes smaller? how do they grind it?

[Blown V6 Hatch]

On a regrind, they reduce the base circle (point of 0 lift) of the lobe to get more lift on the nose. Basically, they're just altering the position of the lobe in relation to the centreline of the cam. Be careful though, in most cases you need longer pushrods and/or adjustable rockers to make up for the loss of metal on the base circle of the lobe.

am i better off just buying a cam??

[Blown V6 Hatch]

IMO, yes. I wouldn't use a regrind cam, unless it was a roller cam as they're a steel billet, even then i'd probably just buy a new cam.

fresh cam it is, how much you think they are for geminis?
