Just a little curious but about how much boost can a stock 4.8 bottom end handle? Or would a better question be, how much power/torque could I make with a stock bottom end without having to worry about anything going KABOOM?

You can do right at 10lbs on stock internals. That will give you quite a bit of powerQuote:

yeah I was just talking about reliability lol. everyday driving
i ran 15 on my 4.8 for awile with my paxton novi 2000.4.8 is a pretty tough motor.
My POS walbro looses pressure once it sits for a few minutes. I have to turn the key on and wait for it to pump up for a second. Sometimes it doesn't and I have to cycle it a few times to get it to pump up.
