I'm wondering how big I could go before running into trouble. Also, on a higher compression NA motor, what's the theory for in/out duration?
I don't want a HUGE cam that lopes hard (which wouldn't pass anyway), but I could certainly tolerate something slightly more aggressive. I guess the best question is what are the gnarliest street legal cams in 01 F-Bodys.

That is a tough one. it takes about ten degress more duration to get a drop in compression. Closing up the LSA will also bleed off some compression, but pass smog-- that is a tough one.
Just for info--- My cam has 254 degrees at .050 ---flat tappet solid lifter.
