Hi guys,

I'm new here. My question is going to sound novice so don't be too hard on me, but here's a question for the cam gurus. i've read a lot of threads and i'm confused by the different number of choices and various iterations of the 6.0 V8. I have a new 2012 3/4 ton Suburban with the 6.0 V8. Everyone tells me that the car is detuned and a cam swap will net me 100 flywheel horsepower. If this is true, which cam would I need to get there (or cam/exhaust/tune)? Assume that I'm not trying to maximize torque and would install a high stall torque converter, if absolutely necessary, and assume that fuel economy isn't an issue. I'd like to get this project done this spring. Thanks.

 

something in the mid 220 duration would work well. But 100hp will be pushing it. More like 70hp.

And welcome to the forum

 

Wow that was fast - thanks!

So, with a cam, I'm looking at ~420 horsepower? Could you recommend a lift or particular cam?

 

Thats how we do it lol. about 420 to the crank maybe lol

 

420 to the crank should really wake this truck up. I just made the transition out of a Bentley Turbo R and I really miss the torque. Is 500 within reach with different heads (I'm not sure I'd go that far, 420 would be plenty, but I'm considering all options)? Once again, thanks!

 

the normal bolt-ons will help. Long tube headers, exhaust, intake. Hopefully some of the more knowledgeable guys will chime in and help you out.

 

First question I would ask is what are you wanting to do with the truck? A 3/4 ton suburban is a rolling tank. Do you want to tow anything? Drag race?

 

I'd say with all the bolt ons, a good cam, and a good tune 100 over stock is damn near possible, but from a cam/tune only... no chance.

The way I see it you can get the 70 HP Andy mentioned from a good cam and tune combo if you have all the other parts in place (like LT headers etc). Intake, exhaust, and headers combined *could* be worth that extra 30. Your 6.0 already had some nice heads and a good intake manifold so there is no need to swap that out. Since your truck is a HD it has a lower compression 6.0, maybe milling the stock heads a little would get you closer to your goal of 500. 500 to the crank is a very attainable number with the 6.0, and your stock L92 heads are very capable heads, but it won't be mild. People have put 500 down to the wheels with a stock bottom end LS1 (through a MT car chassis though... HUUUGE difference).

I would look up Pat G on LS1tech. Let him know what youre looking for and he will spec you a cam for that beast.

You already have a huge leg up on a lot of people because of the L92 heads and 6 speed tranny. Considering how much of a pig a 3/4 ton suburban really is that thing will be movin pretty well.

 

Thanks for all the replies guys, this is a friendly community and you guys have been helpful!

Truthfully, I am looking for hard acceleration. Push the pedal to the floor and have the truck fly. 70 more horsepower would really get the truck moving. Above a cam swap, what kind of money would need to put into the truck for a true 500 horsepower?

 

I'd say FI. A Maggi would be sick!
