gen 3 6.0 max hp hey guys. im wondering how much hp the stock 6.0 short block can RELIABLY handle on e85. i read on superchevy that they made 1,543 hp with 28.5 psi on 118 octane race gas when they exploded a rod. all they did was opened the ring gap on the stock rings, got ported head and a BIG cam along with injectors, tunnel ram and a 105mm throttle body. also, can some people share their big hp combos. i perferably only want to know the ones running 93 with meth or pump e85
thanks for all replies

It's a hard thing to answer accurately. I think gen 3 internals in general are good to about 600-700hp whether its a gen3 4.8, 5.3 or 6.0.
You can make a lot more than that, but if your being quasi safe about it then just doubling the stock hp is probably what you're looking at.

The pumps are the same on the gen3 stuff no matter the displacement, Melling M295. Different pickup tubes and stuff like that obviously but same pumps. The pumps are good for 1000+hp.
You're easily going to break a gen3 rod before you the pass the pumps limits. The weakest link in your entire setup will be the rods unless you decide to use a 4l60e/th350 or something funny like that. I just got through hunting down an LY6 6.0L over an LQ4 just for this reason.

Honestly though, if folks know your vehicle setup (all the details), application (street, reace, etc.), goals (hp, et. etc.) and budget, they can provide much better insight into what "they would do if it was theirs".

i know this is getting way off topic but how much better would a 4.8/5.3 be for boost.
1. 4.8l pullout: 2200$
2. 5.3l pullout: 3000$
3. 6.0l pullout: 4000$
4. 8.1l pullout: 3950$ (this one is here for kicks and giggles
)

They're all the same save for the fact that you'll be running higher boost the smaller the engine. They all will safely make the same HP. At what RPM it makes power and how much torque you get and where you get it will change but the max power of them all on stock internals is the same.

The 8.1 is technically an LS engine. But for discussions about boost...it is not the same as the other engines. They dont have the same rods or anything. Everything in the 8.1 is just for the 8.1. No interchangeability with the others. They are great towing engines though, duramax levels of torque.
1200hp is not going to be reliable. 800 will be, but over a 1000hp and you're at the craps table with factory bottom end in my opinion. It makes that kind of power on an engine dyno, which is a lot different than throwing it down to a set of wheels. There are no jarring moments when the wheels grab hard or you get wheel hop or something. That stuff invites Uncle Rodney to the party and he arrives like the Kool-Aid man.
If you are shooting for 1200hp though, get the 5.3 with an iron block. Thicker cylinder walls, cheaper and easier to find, more used parts around for it like the pistons and rods. You can ebay gen4 rod sets for $100 for all 8.
I make my big power on a 5.3 with a the biggest single t4 I could find. I'm putting a 6.0 in the '68 c10 I just got because I'm going more of a 'sports car/truck" route with it with fantastic handling and brakes and probably a max of 600-700hp with gobs of torque in the 3k RPM zone. Truck cam, small twins or a 78/75 with a 2" hotside...make it spool up in a traffic jam lol.

Are these supposed to be prices for a used engine?
