Question, Who here is running Boost on a stock bore/stroke LS1/LS6 with just forged Rods/Pistons??? And if so how confident do you feel in your motors ability to perform without worring about the big bang theory??? The reason I am asking is that I was currently building a Forged 408 LQ9 for my STS Turbo build on my GTO and now decided to scrap that project and just use my stock LS6 block and just forge the rods/pistons... The Cranks on these motors are good for around a 1000hp so Im just going to pin the crank and run with it... This will save me a TON of money and for the results Im going for "600whp" this should be sufficient enough to get me there and then some... Im going with a upgraded Billet 67MM turbo and planning on running 8-10.5psi of boost... I might scrap the 241 heads and go with some 317's but we will see what happens... Im probably going to go with some flat deck pistons with some good rings and ARP bolts ect... The Valvetrain and fuel system on my car is good to go all I need now is Rods and Pistons... Anyone have any suggestions or input on anything im missing or should do differently... Thanks guys...

EDIT: Also if anyone is wondering how many miles are on my motor it has 30K, 17K of them driven like a old lady....

hey man, i couldnt find any 346 pistons when i went with a forged bottom end so its a 347 with mahle pistons and scat h beam rods, stock crank with arp studs, i spray a 150 shot and it has bounced off the rev limiter a few times and have had no problems what so ever, seems to really like the nitrous :]

I would think you wouldn't have any problems achieving that horsepower and be safe. My first setup was a D1SC with 8lbs of boost and I made 566 rwhp stock motor except heads. Then it was forged, rods pistons and trick flow heads, arp studs with a stock crank and made around 770 rwhp with a F1a (17lbs of boost) and I have no problems.

people have made 1000 horsepower on boosted 347s. You wont have problem getting 600 with a decent amount of boost.

IIRC, LG made 800RWhp/900RWtq on nothing more than a forged bottom end and Turbo cam with an APS TT kit. Use quality internals, and you should be fine.

Nice guys... Funny how they say 347 when are motors are actually 345.69ci which is closer to 346... Oh well...

i think the owner of coperformance on here has a forged ls6. makes around 980rw

its because of the hone, the hone brings up the CI to about 347.

Personally i think your going a good route and i would run the 317 heads and maybe a zo6 cam for a nice budget setup that would easily get you to 600 wheel horsepower on 10 psi.

Just use good internals when you forge it and treat it good and you should be fine
