This is related to bringing my LS C3 Corvette back online, however, because it is a very specific cam question, I will ask it in dedicated thread.

QUESTION
What IS the largest I can go before I can't pass the sniffer?

ASSUMPTION
Declared as 2001 F Body
346ci and 11:1~ comp if it matters

TARGET
Street performance and passing sniffer.

HISTORY
Mine was advertised as 224/224 114 LSAm .566 lift. My understanding is that this was a common "smog" cam, the biggest you could go before busting the sniffer. I have stock manifolds and OE cats. Despite the cam, heads, LS6 intake, and larger TB I always passed the sniffer by a fair margin. Depending on how things go, I plan to get custom headers including hi-flow cats.
