Hey everyone, this is my first post in this group so go easy on me if I screw up or if I shouldn't be posting here.

I'm rebuilding my 5.3 and I'm hoping someone knows if this cam will still allow me to pass CA emissions. The technician from Comp said I should be fine. I'm just looking for confirmation.
Here are my modifications,

5.3 boring to 5.7
Ported intake manifold and throttle body
Stock 799 heads and valves, milling them for a bit higher C/R
Underdrive crank pulley
Headers & Flowmaster Super 44
3.08 to 4.56
Blackbear tuned

2000 and newer they dont do sniffer test, so as long as theres no Check Engine lights or stuff that doesnt have CARB plates on youre good.'

That's a relatively small cam even for the increase in displacement and likely you wouldn't notice the difference in emissions even if it was put on a sniffer...

That small duration with that wide of a LSA should do fine.

Thanks for the input guys. Being that both of you have referenced that cam as being small, is it even worth installing or should I move up to something larger? That's what the tech from Comp recommended when I told him that I'm restricted to emissions testing, I just want to make sure I'm putting something in that's worth the time and money.

I think that is similar to the early LS1 cam with a wider LSA and larger split in duration.

it depends on your goals. Any thing will be an improvement in power over stock.
