Hello,
I would like the part numbers of a 2000 LM7 camshaft and then, the part number to a 2004 LM7's camshaft.
I suspect there to be a difference for a couple of reasons.
1. I see too many damn '02+ trucks running quicker stock vs. stock than the pre-trucks.
2. The '02s+ run stronger on the dynometer.
3. GM is known to do little changes without anyone knowing.

Supposedly, the tunes are better. But, I've yet to see how.
Possibly this can be solved if someone can just show me the differences.

Before you call me a crazy *** bastard, just give me some logical information and I'll stop this conspiracy stuff.

Thanks,
Kyle

Cams are the same, Knock retard is a bitch in the pre 02's.

 

older models have more miles on them also...
