I have a L76 motor out of an 08 max pickup. It has the 823 heads and aluminum block. I was gonna set it up for a turbo or supercharger and was wondering how much power will it take with most everything being stock? Was gonna replace the rod bolts on the bottom end and maybe have the heads cnc ported. New cam-Getting rid of the D.O.D. Other than that everything else will be stock.

How hard can I push this setup like this. Basically how much horsepower will this take. I think the motor is 9.5 compression btw...

Safely 600 RWHP max would be my estimate. I got hold of bad gas and broke a ring land on number five in mine. So be careful.

I see they only recommend 550 hp with the stock pistons in all ls motors without forged pistons and I think only the new zr1 ls9 vette has forged pistons. I see alot of people pushing them way past that though. So I'd say your pretty close on 600 rwhp judging off of that.

Like I said, it's just an estimate, but mine held for a long time at 601 but bad gas=killer It's my own damn fault though, so I'm in the middle of a rebuild

I would definitely add ARP head studs to the list.

Yes sir it will have good head studs and head gaskets since it needs rebuilt anyway.

I dont know how much power i was making but i broke a rod trapping 113mph 1/8 mile times.

Too bad we can't get a package deal on two sets... Lol

I'm not sure what that converts over to 1/4 mile times but sounds like you have more than enough power. That car must really hook up.

IDRIVEAG8GT

Right?! Good luck with your build yo. Um, just a hint I got but the stock crank should hold upwards of 800 RWHP, just the rods and other crap start failing after 650RWHP. Cheers!

eBay has ARP studs for 262.95 a box that suite our application.

Thanks man... Same to you bro. I hear ya on the crank but if i have to buy rods and pistons already, I might as well stroke it out too!! I'll have to check out those head studs when the time comes. Scoggin-dickey have head studs for I think 269 if I remember correct. Not sure what shipping is.

IDRIVEAG8GT

Yeah man, know what you mean. My build is consisting of a stock stroke, but a much lighter Callies Dragonslayer Crank, Compstar H Beams, and Wiesco flat tops with side coating and valve relief. Lighter stuff and stock stroke so I can spin it 7000

Whoa nice.... Gonna be bulletproof. What are you using for heads on that setup then?

I would install ARP for rods , heads and main .

You should get the right cam for this setup to reach 6xx range

I'm running GMPP LS3 ported heads. The cam in my sig goes good either boosted or N/A and works with stock converter. 3 degrees of overlap and lopes just a wee bit.

If you want a sick cam I can help!
