Hi,

Long story short, I'm consider a Z06.

Is the 01 Z06 suited for a huge cam, to make it more of a beast than the 2002? I'd be looking to increase acceleration more than top end speed (I rarely go over 100 mhp)

Or should I just try and get a 2002, as that cam is as good as it gets?

Thanks for the advise
Paul

Are you serious? LoL

an LS6 cam is small in comparison to the aftermarket cams that are available now.

If you want low end to mid range power get a cam in the 228 range

That's music to my ears desertLS1.

A 2001 Z06 would do me very nicely indeed then.

Thanks for the info, and sorry about my current ignorance about camshafts hope to change that soon, and thanks for the guidance for a cam too

I feel gm cams are always lacking in power ,they are old limited lobes in design.I hear a lot of good things about Engine Power System cams,EPS.Check out TSP cam kits .Who is doing your tune after the cam install?Down load camquest6 from compcam and play around with different grinds.Go to compcam website and look at their cam selections.

If you want acceleration, the best bang for the buck is to put taller gears in the back (I like my 4.10's), but you'll shift 10 mph sooner and lose Hwy mileage. I just ordered an LS6 (2004) to replace my 2000 LS1. The heads and valves are awesome, but I don't think you can lift those valves higher than like .550; maybe an ASA cam at most. For stock cams, the 2004 LS6 cam is the best; about .025 more lift and a few degrees more duration than the 01 cam. You can see a comparison here: http://www.smokemup.com/tech/ls1.php

hanks for the advise, a lot of that terminoligy went over my head, but I hope in a few weeks time when I reread all this, it'll all make a bit more sense!

Cheers for the advise

Could you please explain to me why you can only lift the valves .550" on LS6 heads? I'm anxiously awaiting your answer.

I'm no expert, and I'm probably wrong, but I THINK there isn't enough room...., but I'm a newbie, don't listen to me

There is nothing wrong with doing a larger than .550 lift on ls6 heads/valves. You do have to do the normal things like valve springs to accomodate that lift. The stock springs maybe only good to .550 but you can get after market springs that go well over .600.

To the OP, I personally ran a 232/232 600/600 in my stock ls6 for several years till I broke the timing chain. The things that make a 02+ z06 better than a 01 are all the bolton stuff you are going to do. The factory 02 cam is slightly larger, they deleted the precats in 02. Headers and xpipe are going to change the cats or get rid of them completely. An after market cam is going to way bigger than even the 02 cam.

The only thing that you wouldnt change in just bolt on stuff is exhaust valves in the head. The 02+ cars got hollow exhauts valves. If there is any gains hp wise its minimal at best.

do alot of cam thread reading ,learn every thing you can about valve train before you buy a cam.ask alot question ,maybe you will get some correct answers.read the sticky on cams that will help you out some. people are running such big cams compared to 5 yrs ago.

Sorry, "keeping the stock valve train" was missing.

[EDIT] Why would he keep the stock valve train? Because he already said he liked 2001 stock cam, and maybe he doesn't really want to worry about replacing after-market springs every other year or so. So if you're keeping the stock valve train, how high would you try to lift the valves? Sorry if I made you very anxious...but the whole point was about stock-like cams...

taws6, you are getting some good advice here. The main thing to avoid is going too large. Changing gears will definitely give you more acceleration, but with some costly parts and labor required. If you have a good drivetrain shop in England that you can use for this, then go for it.

You may be better off selecting a combination of parts that makes more torque than horsepower, commonly referred to as "power under the curve" in this forum. You can make significant gains with cams in the 21x to 22x range of duration. They may not have the agressive choppy idle that so many people desire, but strong performance on the bottom end usually doesn't come from that style of cam.

Also, I noticed your bolt-on mod's to your TransAm did not include headers. Are there strict emissions requirements in your area? I am sure you are aware, but many of the same performance upgrades can be applied to your current car to make similar power. Headers, Heads and a camshaft change can net you 100+ rear wheel HP over your current configuration.

Hi hammertime

That's good to hear, I wouldn't really want a huge choppy idle, 'power under the curve' is more what I'd want to aim for.

As for emmisions in the UK, I would need to keep cats with LT to stay legal, OR go to one of the many 'friendly' emmision testers, who will pass my car without cats. Problem is, I plan to move abroad when the housing market picks up, and I wouldn't know any friendly testers there, hence why I'd go with cats.

I was intending to finish the exhaust, but I'm now thinking the Z would be a much better car for me, as the roads where I live a narrow and twisty, and even with Konis, the WS6 just doesn't handle as well as I'd like....

Thanks for all the advise,

I just skimmed through the first few posts of this thread and I'm disturbed at the amount of incorrect information that was just thrown out there without a thought... yikes.

taws6, hammertime and silver408z are offering good advice, use their replies to make an educated decision on what you want to do.
