Well its not my engine and the customer doesnt want to pay $5000+ for heads, rockers and intake.

I already have a Direct port Nitrous from Nitrous outlet on his LS7 Intake
So yes it has to be LS7 Style.

He's looking for 550rwhp N/A Since the cam is very mid and only 11:1 compression and close to 900rwhp with 300-400shot.

Her is some pics of the engine







Huge thanks for TSP For awesome build on the engine and nitrous outlet.

Nice engine Well only looking for 500 N/A you dont need the best flowing heads. AT 900hp you can still use the 4 bolt set up. But if your set on 6bolt heads there only a few and they cost alot for the ls7 All pro First/ then id look into ET but they take a while to get.

Ive looked for the pasted few months 6 bolt is big money in ls7 style. Reason i went with 6bolt TFS245 heads maybe little less peak hp but cheaper and better TQ over rpm range

Hussam,
We've only got AllPro's in the 6-bolt LS7 configuration. Overkill for a mild HR LS7 unless you guys have trouble sealing the 4-bolt head. Perhaps one of the other sponsors has something more appropriate for a mild HR build in stock. Good luck!

If you are in a bind for the 6 bolts LME can convert your current factory LS7's to 6 bolt per cylinder. We have done this mod to quite a few sets of heads, both factory castings & aftermarket with great results. One set of L92's we converted is holding 1200+ RWHP with a Cometic MLS gasket. This is on a turbo application. The price is $700. for the conversion. Let me know if you have any questions.

Thanks,
Bryan

Thanks a lot for the reply I looked at AllPro those things are really expensive.
I'll let you know if the customer wanted to step it up.

We still didnt run the 4bolt but the owner already thinking about 400+shot thats why I talked to him about 6bolt when we ordered the engine we talked about 300shot.
