I want to eventually put a procharger on my SS but before that i wanted to put a cam in. I was wondering what would be a good cam to run with the blower in the 6.0 motor. would the Z06 cam be a good blower cam? And if i didnt go with the blower, what would you guys reccomend i run. I am planning on running a 3000 stall as well. Thanks

Anyone?????

Z06 cam is for a light car and top end power. So no to that in a truck.

A 214/220 114lsa is nice. Depending on how radical you combo is, and boost levels you may want a something larger. I plan to run a 216/224 114lsa with my heads/cam swap this summer. That will be a great FI cam in the future and will be nice for some cubes when the time comes. I am unsure of lift as I dunno if I will go with the big ratio rocker (I probably will).

Lift will depend on your use of rockers. If you go with the factory 1.7 get a higher cam lift. If you use the 1.8(5) ones get a bit less cam lift as you may have piston to valve problems.

I use a Comp 212/218@114 in mine and it seems to do alright. I will use a 02 Z06 cam in my new motor.
I thought about the lack of grunt at low rpm but, I think I might up the boost and short shift it. Stay at 9lbs. but have boost build quicker and shift at 5800 or something. Just to see what happens. A stall also helps.

I'm on a roll posting about the 2002 ls-6 cam.

the specs are 204/218 int/exh .551/.541 LSA 117.5
this cam was used in the silverado SS regular cab shown at SEMA NOV. 02. ls-6 intake,ls-6 cam, stock LQ9(ls-6 springs and retainers) no exhaust mods or headers.
if you look at the specs the are much shorter than most of the aftermarket cams 204/218 good idle and great mid range torque.

First, you'd need a stall converter for an ATI and/or a big cam. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> Does that truck have a 4L60E or a 4L80E behind it?

Why not add an ASP pulley? $200 for ~10-14rwhp isn't that bad. Don't forget the air intake and a ported TB. And some longtube headers also.

Why not go to a set of ported and polished 5.3 heads with bigger valves to pump up your compression to about 10.5:1-11.0:1? <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

Then get a nice grunt cam. You need intake duration for more low and mid power. Those cams I listed are great. If you go much over those durations, you will be shifting around 6400rpms...a bit high for a heavy truck IMO.

5.3 heads, long tubes, good cam, and a 100 shot and you will be like <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> after slapping around a Harley-Davidson or Lightning...

I don't see why you wouldn't get close to gaining around 75-100rwhp like that w/o the spray.

Easily a low, low 13 sec truck.

Thanks for the info.

The more i think about it, the more i want to just do a good head and cam job with a nice big lopey cam, and then like a 125 or 150 shot or something like that. I think that might be better with 10:1 compression? what you guys think?

I already have a UPD intake and LS1 fans and im already planning on a 3000 stall, and some ASM headers. The truck has a 4L65-E trans in it.


Does anyone know how much my compression would raise with the 5.3 heads? And are there any disadvantages to using these heads? I thought the 6.0 ones flow better, or is that just because they have the bigger chamber or something?

I doubt ill do pullies because im still not sure about the procharger idea, and i dont want to slow down my alternator because of my stereo. Im also thinking about doing an electric water pump too. Dont they make them for the LS1s now?

the 5.3 heads will boost your compression to the 10.5-10.8 range the 6.0 heads have 72cc chambers and the 5.3L have 61 cc. but you'll have to change valves in the 5.3 heads 1.89 intake vs. 2.0 in the 5.7/6.0 heads. the 6.0L heads match the LS-6 heads in flow up the .400 lift height. ls-6 heads have 64 cc chambers.
