Default need help on n2o cam

Looking for a n2o cam for my 355 rebuild going on here soon, but it needs to let me pass emissions on GA sniffer. Any thoughts? Really looking to do an off-the-shelf rather than custom grind.

Do not bother considering the nitrous as it applies to the cam when talking such a small shot. Pick a cam you will be happy with NA and it will be fine on the bottle. Leave the "nitrous grinds" to the much larger shots.

The sniffer is going to be the hard part. I do not have such concerns so I have not followed exactly what does pass but maybe consider something like the GMPP 846, it is right between the HOT and 503 duration wise. Often overlooked but a solid performer.
"custom" cams can be had for off the shelf prices though through most retailers. Could call Comp or Crane directly and hope you get a good tech and they could give you a PN to order through Summit or get it from someone like Advanced Induction who offers custom Comp cast cams for the same as an off the shelf but you get better than average help in choosing the lobes. I am sure a bunch of vendors here offer the same and I would do that before letting a "tech" at one of the cam companies help, at least if you call a LT1 specific vendor you get someone who knows the application.
