Blower cam help!
Due to unforeseen issues I am dropping the entire drivetrain from my c6, and while I have it out I’m going to put a cam in it, question is what cam is going to work best for my ECS supercharger I’ve got sitting here waiting to get installed. It’s a 6 speed so no worries about the torque converter, I was going to do methanol injection but I feel the cam is a better way to get the power. I’ve looked at the ECS big blower cam, and some texas speed cams, I know there is a lot of options out there but I’m looking to be in the 650 hp to the wheel range.
Thank you!

i want at least 650 hp at the wheels, I’m dropping the entire drivetrain tomorrow and putting the engine on a stand. Going to talk to my engine builder to see if it’s worth it to put forged pistons in it while the engine is out. Then if I decide later I can crank it up and not worry about it.

You do realize that the LS3 in stock form will handle a ton of horsepower reliably right? If you want to make 650 that's fine but with a cam, meth and blower you can make 750rwhp super reliably. No need to build the motor unless you want to venture into the high 800s and beyond
I have the LS2 not the LS3, and no I don’t know what the limit is on the stock bottom end. I just know I’ll have the engine sitting on the engine stand tonight and I don’t want to have to pull it again to do something I wish I would have done. I don’t plan on taking this car into the high 800hp range. 650 to 750 should be sufficient for a play toy.

Pistons alone are rarely worth it. Doesn't get you much for the cost. Either do everything, or nothing. Stock ls2 will take that power all day long. The machine work/cost of pistons just is not worth it unless you want to do rods and other items while in there.

How safe is the LS2 at that power level? I don’t want to be right at the max flirting with disaster if I can help it.

500-750 is still pretty safe in my opinion with a good, knowledgeable tuner. Past that you understand the risk is going to go up with power. But there are lots of cars that make 8-900 hp with SBE Ls2 and 3 and live for a longgggg time.

Pistons and rods
So tearing my LS2 apart my brother and I found part of the timing chain guide in the bottom of the oil pan near the pick up tube. That chunk of metal got beat around in the bottom of the engine... and since the timing chain was loose a couple of the pistons had valve marks on them. Hadn’t planned on putting pistons and rods in it but here we go, she will define ready for some boost
