You can upgrade rods and pistons along with some fuel system upgrades and get even more power. My plans are to take my stock LS1 and upgrade the pistons and rods and shoot for 650 wrhp. The stock crank is said to hold 800+ HP without any problems but the rods and pistons are not up to par.

Im still a good ways from building the tubo setup but I have lots of ideas. It would be nice to see someone else go through this before me so I can see what kind of problems you run into. LOL

I have been driving mine for a year with no problem yet.

A stock block and crank have held 1500 hp!!

Thanks for the all info. So if we are looking around 500 horsepower on a stock motor, ( thats the limiting factor damn it) that would be doible with the head and cam combo the conventional way. I have to think and decide.
I think doing it the right way starting building the engine for turbo and the twin system is the way to go.

If you only want 500 hp at the crank, go cam and heads. If you want more power by turboing it, Leave the cam and heads STOCK. You can make 650 hp with turbos and NOTHING else. If you forge the rods and pistons, you can make 800 hp with the rest of the motor being stock.

Are you serious about 650 horsepower without doing nothing to the motor?
How much risk involved to have that kind of power on stock engine with turbos?
Thanks

That's the max power it will put down with a GOOD tune and be a great weekend worrior. Alot more then that you will likely snap a rod. But yes, all stock. Don't even have to open a valve cover!

If you want it to last 150k, I would keep it around the 600hp level and you won't ever have to worry for the life of the car.

These motors have made 800 hp without opening a valvecover, but that will NOT last very long.

https://lateral-g.net/members/tt71chevelle/

Here is the link to my Lateral G buildup. Some stuff has changed for more power, but this setup made 750 RWHP on 93 octane, I am now making over 800 rwhp with larger turbos and more boost. I am running 18.5 PSI on 93 octane!

Feel free to ask questions, I should have an answer.
