What kinda cams for an ls2 engine. I don't want a rough idle and i need power around mid range. The ls2 start at 405 horses, throw a cam in and they are at 490's. It's sick. but what kind. as previously stated, smooth idle if possible. Also should i even go with the ls2 engine, i found it new for 5300 and i don't think i can put one together ready to rock for less than that.
490 at the fly is more like it rather than the rear tires. My buddy in his GTO put in a big cam, LT's, and a FAST manifold with some other bolt ons and put about 470 rwhp
Wait, the LS2 is 400 to the wheels or to the crank?

Im also a little bit slow on cams, I don't understand their discriptions with all the numbers, and size ect. ect. also what does it mean by "chop"
Chop refers to the idle being choppy or rough,Quote:

tight LSA's 112 and under will have more of a lope at idle a peakier powerband and will usually produce more mid range torque
Damn man that's nasty. I didn't know the ls2 was that much better. I would imagine an ls1 would be around 430 rwhp with the same mods.Quote:

Thanks for the angle clarification, i definetly don't want a choppy idle, i like it smooth, strong and sweet soundin.
OH and I am a new member. Not exactly sure where to go specifically to post threads, i just figured anywhere but if there is a more appropriate place, i understand. Thanks for the assistance
I heard the MS4 is a mld cam for the LS2. But we all know what it's like inside and LS1
Whats a good cam for an LS1 and a good one for LT1?
I am looking for something that will sound nice, even at idle, and just the best preformance over all. I seen voodoo cams pretty cheap and then I see comp cams at like 300-400 dollars and the vooddoo was like 127
The LSA will have that effect on cams of the same durations. However LSA is not what equals "chop" Overlap ="chop"Quote:

Which one do you think will lope harder??? It is not even close. Cam #2 will sound like it is about to eat your children.
Usually you get what you pay for.Quote:

it's the site i was talking about in reference to the cam package for ls2. pretty sweet info
A cam swap is MUCH more involved than just buying a cam.
$400 for the cam is just the beginning.
Valvesprings, pushrods, gaskets, tools, etc. are needed as well.
