Callaway Peices

[jdbubb at verizon.net (Dan Bubb)]

It's a pretty mild performance upgrade, but 10? more duration and almost a millimeter more lift than the 1.8 cam.
Can't complain for -0- cost.
A "G" grind would only add an additional 8? and 1/2mm on top of that. So, a decent upgrade.

So the cam is probably a stock 1.6 cam. The 1.5/1.6 cams had .405 lift, the later 1.7/1.8 cam (THE lamest of the bunch) only had .369 lift. The stock 1.6 cam is not a bad thing. You don't want to go to a hotter cam that has a lot more overlap. It won't work well with a turbo although a custom grind with more duration or lift would make more power as long as the overlap was kept to a reasonable number.
