They like a little shake, ever wonder why they like bikes? An old Triumph twin will do a better job than any guy.

Duration is what gives you a choppy idle. Duration is how long the valve is opened. You will notice choppy idles starting around 212 intake duration @ 0.50". More lift means more air and fuel into the cc. The LS6 cam is borderline from smooth to choppy. Its 207/217 .525 lift for the 01's but the 02's have slightly smaller intake duration but more lift. Something like this would be what you are lookin for. I mean hey they put these cams in 405hp motors. These cams in a 5.3 gives 50 hp increase on engine dyno.
There is more than one factor contributing to the idle characteristics. Duration IS how long the valve is open but is not the main factor in deciding idle character. What makes in lope is valve overlap which is heavily influenced by loba seperation (LSA).
Yes that is true. Widening the LSA reduces overlap and narrowing it makes it worse.Quote:

Since I couldn't find too awful much about it I thought I would ask the board and see what everyone here thinks about the specs of the Cheater v.3:
Thunder Racing Custom Camshaft
" CheaTR v.3" - 219/230 .607/.604 117 LSA. Off Idle-6800 RPM Power Band.
I am absolutely no cam wizard and I have seen threads at least all day on the TR220 or TR224 not to mention Youtube Vids galore! Should I go with his advice or stick with a sure thing?!
Don't forget its a stock 5.3l into an OBS swap, mods will include: Schoenfeld headers, 3in exhaust, Intake manifold (havent decided which one yet), Converter, and gearing will come once I get the rest outta the way! N/A for now unless NOS starts calling my name in the middle of the night! lol (hell just looking to make it fun)!
I think thats kinda similar to the Torquer V3. Plenty of duration but you dont lose alot of low end cuz of the overlap. Plent of lift also for more fuel and air. Id say go for it. Its very streetable and will give you lots more torque.Quote:
