As for the gears, for a M6, here's my .02
3.73's are nice on the street but don't feel much different than 3.42's.
4.10's are more fun on the street but will fry the tires with ease. DR's are a good idea if you want traction.
For street 3.73's are better for the track 4.10's
Turning more RPM helps with the bigger the cam too. So I went with 4.10's so my 224 would be fun to drive.

Re: Help me choose a cam/heads Tim, what I'm saying is that a cam w/ .550" lift will work best w/ a port that flows well at .550". Even though a big, aggressive cam profile will "work" on stock heads, best results will be with an appropriately ported head.

Re: Help me choose a cam/heads I suggest going with a proven winner such as the MTI stage II heads and HAmmer cam (C1) or better yet the C2, which will put you well into the 11s and give you all the reliability you want. Its a proven dependable set up.

Snifer may be around in counties without emissions issue for a while - it's a phase in as I understand it.
A 224 could pass sniffer on a 114 LSA it would need tuning & probably LS1 edit to tweak it. Might not be too easy to get to pass but some say that they have done so with other sniffer tests. Natually, a cam this big will needed cats etc.
I know a tuned 216/220 114 LSA blew a 77 on the sniffer test and 220 is failing. If sniffer is an issue a 220/220 on a 114 LSA will be easier to get to pass than a 224.

Re: Help me choose a cam/heads MTI Stage 2 LS6 heads and X1 cam. Power is awesome. 420RWHP and 400RWTQ N/A. Driveability is good as long as your not stuck in stop and go traffic. The X1 will give you a bit of cam surge at parking lot speed but other than that the car plants you in your seat and keeps you there until you lift and if great just getting around town.
