What cam would you suggest? Please Help
It's going in a 2002 camaro with a stock ls1 bottom end (346) with the following mods: built 4L60 with a yank ss 3800, full BMR suspension, 3:73 rear gears, Stage II heads with 2.02/1.575 valves, fast 90 intake, 92mm nick williams throttle body, 42 pound injectors, comp pushrods, comp dual springs (pt# 26921-kit) with comp titantium retainers, terra 1.7:1 rockers, Mac 1.75 mid headers, 4" exhaust system, it has a Lunati cam in it now (222/218 581/562 LSA: 114 adv. +2 degrees reverse split). This is not my dd car. I drive the car on the weekend and take it to the track. I ran a 7.70 at 89.9 mph, with a 1.7 60ft. on street tires. I would like a nasty idle, with a good gain in power. I'm thinking something in a 235 dur and 600 lift on a 112. What does everyone think I should put in it? Thanks for any imput.

With larger valves and unknown chamber size, he may run into piston to valve clearance issues with a cam that big.
You'd probably be happier with a cam in the low to mid 230s with an LSA around 111-112. You'd also not be risking piston to valve clearance issues. A 230/234 .600/.602 111LSA cam with EPS lobes or a 232/234 TSP Torquer V2 on a 111LSA would be great. Hard lope, but not a top-end-only cam like so many others. Big area under the curve.

Pat G, don't you agree he doesn't need a whole lot under the curve because of the 3800 converter?
I say something like a RapTR if Thunder says it will clear.

Most people make a mistake of overcamming and wind up with a cam that is soft down low, mediocre in the mid-range, and do not have enough high rpm mods to support a good top end. The result, poor performance all-around. To get a solid launch, you need outstanding mid-range. That means good dynamic compression and plenty of overlap. The lower 230s cams with narrow LSA would typically run circles around cams with upper 230s for the reasons mentioned above.
