I'm no expert, but I can't help but think I've seen a ton of people with stock LS2/3 intakes make 1000rwhp, so I'm not sure why you'd need a billet intake
Completely possible I'm missing something, though
I wish I had a good recommendation on where to get a more reasonable price, but I don't. Hopefully someone else does.

Don't need an intake at all. Stick with stock. Where are u located? There are a lot of reputable shops nation wide than can build you a solid setup for close to half of that

I'm sure at very high boost levels where people don't even have their restrictor plate in, this is a valid concern. However, in my case with a restrictor plate in place and only 7.4 PSI at max, I'm wondering if I'm safe.

Just spoke to Josh at A&A. He said the old FAST 78 and FAST 90 would break around 12 PSI, but the newer FAST 102 was good too about 16 PSI, so I should be be fine at only 7.4. LMR said the same thing.

I've made 1050 rwhp on the stock block, with forged crank/rods/Pistons.
Most do not push the LS7 because of its value. You can sell it for significant money, vs breaking it and having a paperweight.
Simple economics.
As long as the tune up is solid, and no detonation, you will be fine well into the 800/900 range.

I believe I have the highest whp record stock bottom end ls7. I made 837whp /741wtq on saturday. I'm also using your LG7XX cam and it worked out fine with a single turbo setup. I'll make a thread tomorrow if I get a chance. It's also 13.8.1 compression S480 billet wheel T6. Those numbers were made on 6psi and 10* Timing I'll turn the boost up next time. It's on waste gate pressure for now.

Is your car friendly enough to use as a daily driver, or really just for weekends/track?

Yea Darin did a really good job on it.

peaks at 6300-6400 rpm. its a custom grind similar to the texas speed ls7 blower cam. you could use it as a daily if the triple plate wasnt such a bitch to get off the lights. lighter clutch would be nice. gas mileage isnt ideal either lol. if your building a daily just put some rods and pistons in your ls7 and bump the boost up. dont go crazy with it. $$$ and driveability start to head south

My car is perfectly daily drivable. Put 6k miles on it in last 2 months. High power doesn't need to be rough to drive. Just pick a decent cam. That is the only thing that makes it rough. Well that and clutch if you get a crappy clutch. Only thing you may need to fight depending on environment is heat. Otherwise 1200+rwhp and drive almost like stock, zero issues.
Sold my stock ls7 short block for $3500, which put a nice dent into the $8800 bill for the LSX setup.

How is that relevant? Friends Honda accord missed a shift, blew motor apart. A bone stock corvette can do that. It has nothing to do with what the bottom end can take. Missing a shift and a mechanical overrev can destroy any motor. It isn't like a $20k billet crazy 3000hp motor can die like that just as much as a stock motor.

So everyone knows: I make almost all my power (561 whp before the blower and meth) by motor. I'm running only 7.4 PSI at max boost.
