How much RWHP can the Stock LS7 block handle?
just wanted to know How much RWHP can the Stock LS7 block handle? 600rwhp? 700rwhp or more?
If i wanted to build a +++800rwhp car with an ls7 engine ( LS7 block ) what do I need to change to make it handle that kind of HP?
Sorry for the noob question
Thanks in advance

Lingenfelter has run 1500+ hp & torque with the LS7 blocks in several of their customer's Z06's, w/o any block related failures, so 800rwhp&tq shouldn't be a problem.

There's no way a stock LS7 block can handle 1500+hp and torque.
For 800+hp you will need darton sleeves, lsx block, or warhawk block.
Or better advice, ask your tuner. If you trust them to make 800+whp, you should trust them to tell you what you need to do it. But they're going to say the same thing. Stock block won't do it.

The block yes, the sleeves no. Have R.E.D or Katech resleeve the block. I am not sure what Katech uses, but the LS2/LS7 Darton sleeves are a little longer, which will allow you to use much stronger pistons than the stock length sleeves.

I've consistently made 1,150-1,200 at the wheels on two of my STOCK BLOCKED (with all forged internals and of course studs EVERYWHERE) TT Z06's.
However, when the builds started out this much power was not my goal (we wanted 900-1,000 RWHP). It was just fairly easy to hit these numbers with Twins and Nitrous...
I'd say my luck has been better than average due to ZERO detonation (due to damn near perfect tunes on each car!). I'd say you can get away with 21.5, MAYBE 22.5 PSI before the 4 bolt heads start lifting and the block integrity becomes an issue.
Hope that helps!

Keep in mind guys that surviving through some dyno runs is different from lasting through several years of being beaten on and raced.
If it was me, I wouldn't go over about 800 on the stock block with only studs and forged internals as the upgrades.

Vindication, I'll put a couple up for you sometime this week when I return from TDY. I don't recall you ever asking me for a dyno sheet? However, senility has set in, and I could be wrong.

Exactly where are these 1500+hp cars from Lingenfelter that you speak of, and what makes you think they are using stock unmodified blocks...
The highest package they sell is 1000bhp, which would only translate 800-820whp.

0o (and other disbelievers)- just a little more fuel for this fire...
I layed down over 1,000 ft lbs of torque on PUMP gas with a STOCK LS7 NON-SLEEVED block last night shortly after I made the post before this one.
Worth noting, that motor has well over 8,000 miles on it at this power level and it brutalized every day of the week. Still running STRONG! The piece de resistance - it's a Nitrous motor!
