i know i am scatching the bottom of the barel here to squeeze out a little more power without spending the big bucks on forged stuff, what do you think of this.

looking at that 2002 zo6 cam, cheap cam, cheap springs, your thoughts were it is going to push my rpm window up and the reason 6.0 is still around is because i don't rev the snot out of it. well what about this? what if i don't rev it any higher(for now) keep shifting at 5800. during my entire run i am between 4200 and 5800 and that is prety close to the sweet spot on that cam, i am not 100% sure of there numbers but i have seen numbers listed for the stock 6.0 cam as 198/200 and 500/500, the zo6 has ALOT of exhaust duration and 550 lift, check out this page. http://members.***.net/jason99ta_2/stock60.jpg
looks like the stock 6.0 heads could take advantage of the 550lift cam. another page http://www.corvetteactioncenter.com/...ntranscomp.jpg

what is wrong with my reasoning, if i still shift at 5800 doesn't it seem like there would be a prety good gain? of course the hard part would be not raising the shift points <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

this chart might be better, it compares an 01 z06 to an 02

Why not install the Z06 cam advancd about 4 degrees.That would make the cam come into it's powerband sooner.I would check you ignition timing if you do that because on engine with a camshaft driven distributor the ignition timing is advanced a like amount.I don't think the timing would really change, with your setup 4 more degrees of additional timing could be dangerous.

 

i don't understand the advancing the cam thing, what does that do? and since i stall to over 4k would it really help my ET or just the drivabilty?

 

Jim, your current 6 liter has is a 196 / 207 116 LSA cam with .467 .479 lift. That 116 LSA and large split is giving you good power.

The 02 LS6 cam is 204 / 218 on a 117.5 LSA while the 01 is a 204 / 211 on a 116 LSA. Both of these cams are retarded about 2 degrees.

If you installed either of these, I'd think about advancing them. Get an adjustable chain. I bought the rollermaster because it moves in 2* increments, others make you move 4*s at a time. I'm tempted to use my chain on my current LS6 cam and see how much more low end I gain back. Its just a pain to install just to have to take it out in a month.

My little 01 LS6 has a nice long flat torque and power curve. It looks like it would still go a couple hundred more rpms too. The 02 cam will probably make more power higher in the rpm range.

Advancing or retarding the cam is changing the valve timing events in relation to the crank position. Basically opening the valves earlier or closing them later. The old saying is when you have too much cam, advance it , and too little, retard it. Advancing it should drop peak HP numbers, but will boost up the lower mid range and make it peak earlier. That is what you want since you would be wasting power made over 6000 rpms.

 

When you install your camshaft, instead of lining up the timing marks and buttoning things up.You install a degreeing wheel to determine the actual opening and closing points of the valves.To do this you need a dial indicator to show you when the lifter has risen .050" to tell you when the cam is at it's rated opening point and a stop of some kind so you can rotate the engine forward and backward to the stop to determine true topdead center.When you know where the valve opening are actually occuring,you rotate the camshaft relative to the crankshaft to make the timing event occur sooner.That is called advancing the cam to do this in small increment you need adjustable timing set because 1 tooth on normal timing set would change the timing to much.
