Would you call this a mild, decent size, or large cam.....

223/227 .610/.614 112 LSa cam for a 6.0L LS2?

mild. That doesn't mean it won't produce good power though. By good I mean a broad power band in both torque and horse power. It actually would be a decent cam for a street car trying to make a broad power band. However, it's a small cam and won't produce big numbers. It just depends on what you're looking for from your engine. Also remember the power is made more with the heads than anything else.

I am not looking for all out race motor power. Just want to liven up the LS2 I have from a Trailblazer that is going into the Monte. And I don't want to do like I did with the LT1 by putting a cam in it a little bigger than I needed for fun & street. Didn't like the cam surging I had with it.

A good tune will make that cam in a 6.0 noticeable at idle only. I had a 224/224 in an LS6 vette and it put 398 to the wheels with long tubes & cold air intake. Great manners, but you could hear the cam at idle. I have a 228/232 in my LS1 and its still pretty streetable. Slight surging at times, but a bit more tweaking on the tune using the wideband should take care of it. Should be a great street cam for your LS2 :)

The guy/company that sells that cam says 460-480hp to the rear wheels......?

^ sounds a bit optomistic Scot....

[Samckitt]

Sorry I had the wrong numbers. Here is what I was told:

"430-480 RWHP depending on the rest of mods in 6 speed cars. An auto and stall will dyno less. "

Yes Ron, I thought it sounded a little extreme. Not sure what 480 RWHP would be at the crank, I am guessing over 550. So 150 hp from a cam swap? Sounds high to me. Don't know what other mods would be, headers, cold air intake, tune, throttle body....?

[NJSPEEDER]

480 sounds like a number that would come from full bolt ons and some upgraded heads. You can extract a bunch of power just from the stock computer but I doubt a cam alone can add that much power.

Hey Scot---I've had similar questions related to my cam that came with the LS3 motor. The cam is still in the box, along with the springs. I have debated about just buying another one. My specs are as follows 219/235 @50, 607 621 113LSA. I wanted to have some idea of power with the LS3 and this cam--the following link helped me a bit with some real world testing. Here is the link:

http://www.gmhightechperformance.com/tech/lsx_engine/0911gmhtp_chevy_ls3_engine_camshaft_comparison/index.html

It gives an exhaustive test of 10 cams, with the specific objectives and operating range along with torque and horsepower #'s obtained. Every cam, with the exception of the stock one, made over 500 hp and nearly that much torque. The testing was done on an LS3, which was right up my alley of course, but I believe this may help you get an idea of where you will land. One thing to mention, this motor was run with headers, and electric water pump--in that form, stock trim otherwise, made approx 480 hp. That's quite a bit more than the advertised 430. So it's easy to see how 500 was easily attainable. Hope the article helps.

Be careful comparing an LS2 and LS3. The 0.2 cu in increase is minor compared to the cylinder head change. The LS3/L92 heads are great.

I can see 430rwhp out of that cam with supporting mods ie headers, unrestricted intake, and maybe a ported throttle body. That cam won't have any surge issues if you have a 3.42 or lower rear gear. Surge with a manual is annoying. All you want to do is tool through a parking lot and find a good place to park and the car just wants to buck and kick. So annoying, lol. You'll be fine with this cam Scot. You can always upgrade later if you like. Changing heads in the future will help as well. If you intend to swap to L92 heads though, you'll either need to change the cam again then or rethink your plan of action. A proper LS2 cam will not work well with LS3/L92 heads. The exhaust duration needs to be much longer than what an LS2 headed engine would like. Going with LS3/L92 heads now on a stock cam will actually provide really solid gains and not change how the car drives at all aside from having more power.

[Samckitt]

So this cam mentioned above with appropriate springs is going to run me about $650. Sounds like I should put that $ towards the L92 heads (not much difference in price). What lift will the springs on the L92 heads allow me to go?

[WS6]

I'm honestly not sure but I want to say they could handle that cam. If not, a set of Comp beehive springs will work. Or a set of Texas Speed's dual springs will work too. Don't forget that you'll need the L76/LS3 intake as well as the heads.

[Samckitt]

How about this cam for a 6.0L with LS3 heads/intake?

223/235 .610/.624 114

[WS6]

Should work out well honestly. Same characteristics as the other cam but should make more power due to the better heads.
