Can I spray to 565 on a stock bottom? Last night I had a dyno session at HiTech Motorsport. They installed their new Predator H/C/FAST high velocity combo on my car. (228/232 585/585 114/velocity ported 5.3 heads/ velocity ported 90 mm FAST intake manifold) We are very pleased with the results considering my bottom end is stock
Here are the last three pulls (SAE corrected):
461.28/426.21
462.78/428.95
460.49/430.81
Here are the last three pulls (STD corrected):
471.98/436.09
473.33/438.73
471.15/440.78
Can I spray a 100 shot or a 150 shot with this much power on a stock bottom? Can I even spray a 75 shot? I do have a Racetronix Fuel Pump Kit going in, but I don’t know how much power I can put through a stock internal LS1???
What are your thoughts?

I have seen 680 rwhp on stock bottom end. I have also seen a piston pop at 500...but very rare. 580 should be fine with tuning...especially since the majority of you power is coming NA. I would retard some timing...just a little...or use 100 octane.
I say that because I am assuming your timing is pretty agressive on your NA tune.

I sprayed a 150 shot on my H/C set-up. Just tune it right and run alittle rich. Pull alittle timing and you will be fine. Just don`t run out of fuel up top. DON`T RUN LEAN!!!

Hey whats up jeremy!!
last year i was spraying 150 on stock internals at 572sae. Now this year if brain ever gets back to get my car tuned I'll be at least 580-600. So I guess i'll be hoping to keep it together too.

)It's not nice! I have a rev limiter now. 
But spray and enjoy! 
There goes Ben blowing **** up again! Damn, you fisted your LSX intake....gees.
Making that kind of NA power is pretty damn good for stock bottoms. Tune it and spray it.
