How far have you pushed the stock ls3 sleeves? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Rem0v3r · 02-18-2021, 10:26 PM

I rebuilt my engine 6 months ago, what started as removing a foreign object in the intake, turned into a cam swap.. and while I was in there I might as well gap the rings... and seeing as I'm gapping the rings I might as well do forged pistons and rods and new bearings..

Well im kicking myself for not sleeving the block (because I'm cheap AF)..

so my question is this " how far have you sustainably pushed your stock sleeves (sbe or forged).. I figured 850 wheel was my cutoff but I'm hoping 400 of you tell me 1000+ hp lol.

Did you replace your crank too?

personally the most power I've ever recorded was 913whp, but I know it made 2 psi more on the street (20.5#). That motor is still going in a road raced c6 today.

I see most builders regularly rate a forged ls3 with stock sleeves to 1100 with arp stuff. 1000 with the stock crank is not uncommon.

I know 3 guys locally with stock sleeves making from 830-1150whp, but I'm no expert on the topic.

sleeves are a con game in the LS world. The 4 bolt head fails long before anything else. I am mobbing an LS3 forged with cheap callie stuff, I make 1200 wheel and run 5's ion the 1/8th mile . Its all about maintenance , spot on tunes and good fuel.

Nah, stock crank.. it was a budget build and I know the stock crank can handle more than I was going to throw at it..

I cracked a sleeve at 600hp :-(.. had no idea it was even cracked lol.

Glad to hear dudes are hitting 4 digits.. might have to push it then :-)

Yeah I did.. I kinda screwed up cos I have the l99 and the drop is were for an ls3.. had to get the assembly balanced.. glad I did tbh, I found a cracked sleeve (575hp 640 tq).. it was cheap enough to get the forged stuff and ive seen enough stories of dudes bending rods.. my fatty weighs 4400lb with me in it.. seemed worth it to me.

I prefer the term "voluptuous". LOL!

Js2fst · 02-20-2021, 10:09 PM

I did 806 on a sbe but we had a lifter fail. And after all the failures I saw started to really grow at 850 rwhp. So we already had 6 bolt heads i went to a Thompson dart 427 and not much difference in price
