cams

[lowc]

did a search and no luck. i think i may have 3.0 cams in my 3.2 but not sure it has the koa stamp but nothin else any ideas. and i just finished the upper 60 on half the motor and is it odd that only one of the intake valves needed a shim and all but one of the exhaust valves needed to be done?
thanks Paul

the 3.0 cams have the KOA cast into the blanks. the 3.2 cams use the same blank, but in the machining process they mill off the KOA (or mostly mill it off) so that is the easy way to tell them apart. btw, only the intake cams are different, so the exhaust cams will all have the KOA showing.

Umm, I thought the intake cams were the same, and the exhaust cams had .050" higher lift?
