would this cam make a substantial gain in rwhp? and do I have to change the springs and lifters to do it? also would this be considered a "cam only" car seeing that it's actually a factory GM cam?

IT would be considered cam only yes, because you are still changing your stock cam for a larger cam. Also, I'd guess 20rwhp gain. You don't need new lifters, but I'd recommend new springs. Stock springs suck

Ive done quite a few ZO6(LS6) cams in stock LS1 and you will pick up 20 to 25 hp but to get the full affects as far as performance you will need a set of 918 Comp Cams springs and spome 7.40 push rods. All the companys will just about tell you to run the 7.45 pushrods and I tryed that and when I went to 7.40 I went 2 tenths faster and a 1mph more. The only diffrerece is the valves are a little louder but the LS style motors are loud any way. Have to have rev limiter pulled up to 6300 to 6500 to perform.

hm....cam only

and you're only changing the cam...

i'm confused


bolt ons and a dyno tune and you'll probably see 350-360 rwhp depending on how the car runs.

for the cost...there are MUCH better cams to install.

tr224 would be the obvious first choice.

and YES you'll need new springs with the ls6...it's lift is more than the stock springs can handle. CC918s would do just fine, or the LS6 springs if you want to save a few bucks

As a matter of a fact I am pretty sure I have the one that came out of my car out in my garage. I would sell it to you for a $100.00 if your interested, I took it out of my car when I put the Futal FM13 cam in. It has 20000 miles on it if I remember right. And 1 of the cars I done out ran the several tr224 cam that the guy above me speaks of and dynoed 381 rwhp.

thanks everybody for your input and info! I guess what I was saying is that a LS6 cam is still a factory GM cam and not a "after market" camshaft so technically speaking it's still would be considered "factory spec" but maybe I will just wait and get a MS4 or custom cam?

Agent LS1

You probably won't be pleased with the LS6 cam. I know a few guys that have done it and changed within a few months. You might want to try the Futral F-13. Not too big.

New Era Performance sells a "Street Sweeper" camshaft that is a great street/strip performer. The specs are 236/242 duration, .605"/.609" lift, 110 or 112 LSA. If you are looking for large peak numbers you could always go with New Era Performance "Hellion" camshaft. The specs are 244/248 duration, .630"/.630", 112 LSA. Both of these cams work fine with the stock heads, but the Hellion will need flycutting of the pistons with aftermarket milled heads such as Patriot Stage II 5.3L or Patriot Stage II LS6 heads.

well, ask yourself this. Did it come in the motor? then it is considered aftermarket. GM makes a hot cam too. That isnt stock either.

It makes me wonder if you realize what cams can change as far as power/torque. The LS6 cam is not on the same spectrum as the Ms4? Why such a jump all of a sudden? You can make more useable power with a custom grind.

well I only considered the LS6 cam to keep a the "factory cam" thing going with no "lump" to give it away! but I guess I might as well just look into custom cam's? or Maybe the MTI X1 or MS4 are my 2 front runners so far?

Agent LS1

I was stuck between the MS4 and the Trex. I ended up going with the Trex. Its going in today.

Your .2 faster and 1 MPH wasnt from a pushrod change, lol.
