Cam timing
Can't seem to find this anywhere . How many degrees is one tooth on the cam timing? I'm working on 96 that someone did a cam swap and had no power under 2500 RPM. I found the cam retarded by one tooth. Thanks

Interesting question. It's be a LONG time since I sat down and crunched the numbers on this and I can't, for the life of me, recall what I came up with.
Box is probably right 'cause his little grey cells are newer than mine, LOL
Are we talking cam degrees or crank degrees?

If there's 4 degrees of advance already ground in (which is common), yet you installed it one tooth retarded (equalling 10 degrees of retard as stated) then the net effect would be 6 degrees of retard, right?
Of course, even 6 degrees of retard would noticably move the power band UP, just about killing low end.
Of course, adding to the murkiness of all this, would be any manufacturing tolerance stack. I recall reading recently posts from one member who, when degreeing in his cam, found it 6 degrees off and IT WASN'T CAUSED BY A MIS-GROUND CAM. He installed a different cam in the LT1 engine and came up with the same (off) numbers. Yet, when he installed both cams in a different engine both cams checked spot on.
Ah, the plot thickens (LOL), but degreeing-in the cam resolves all that.
