About 5-6 years ago I bought what was supposed to be a 30-30 Factory NOS cam. Paid $$$ for it and to be honest never really looked at, just had the shortblock rebuilt.My buddy that built the engine pulled it out of the tube and installed it. I finally got around to putting the engine in the car and it ran about 100 miles and took several lobes off. I now believe I've been screwed I set the lash at .028 so it should have been fine. The numbers off the back of the cam are as follows:
11-25-02 pretty safe bet this is the manufacture date
0288 both these are on the cam itself
at this point My guess is it's actually a 288 hydraulic cam that someone stuck in the GM cardboard sleeve???/ any thoughts???
