Default What to expect from a BONE STOCK lm7 or l33 turbo on pumpgas only?

As the title says, what could I expect from a bone stock (except for injectors) Unopened 5.3 with an on3 76 and a decent fmic on straight pump 93 no meth? With be going through a 4l80 and an 8.8 worth 3.08 gears.

Valve Float... Stick some Decent springs in there I'm pretty sure you'll break the 500hp mark

Ok springs only. I'm hoping at least 500rwhp. I know it would be easier with the l33 but they are harder to find than the run of the mill lm7.

Put good springs in it and small cam and let it eat. With good fuel and a good tune it will easily handle 500 plus quite a bit more.
