Also, try car-part.com for cheap 5.3's. $500 seems a little high for high mileage. 100k milers go for around $300 or so around here.

The piston/rod ratio of the 4.8 makes it more resistant to detonation than the other LS engines, which is significant when looking for these power goals on a stock motor. By newer I mean 07+, they will come with 243's/799's qnd the newer internal parts. I wouldn't depend on methanol at this power level, your probably going to need around 18lbs of boost or more to hit 700 on the corn itself. Probably more on pump w/meth, if anything happened to your meth kit it would all be over pretty quick at that boost level. Not sure on the rod length.

Check out the AES boost 5.3 shortblocks. They're priced very reasonably.

It looks like I'm find 07+ 4.8's in the 700.00-1000.00 range. That's with 80K miles or less on them.

Is the throttle body on newer 4.8 bigger than the one on my 5.3?

I think this is the route I'll go someday.

I already have:
4L80E
SC3000 stall
NP149
P1SC
LS1 efans
HPTuners
...and a bunch of little thing I'm forgetting.

I just put my p1sc kit up for sale on Craigslist. I actually need the money for taxes, but eventually I am planning on a stage 4 turbo kit from Trick Performance.

What should I do for injectors and fuel supply?

After a lot of reading on this site, my plans have changed. I've sold my P1SC kit and have pieced together a turbo kit. It's basically a KB racing it.

I have a ls6 cam and a new set of lifters. I'm sort of at a cross road. I think to be on the safe side, I should put in head studs. I can't do this with out pulling the engine. I should also probably swap in ls9 head gaskets. I have to remove the heads to put in my new lifters anyway.

So now I'm wondering if I should find me an 07+ 4.8L and put head studs, ls6 cam, my new ls6 lifters, and ls9 head gaskets on that. While its on the stand, I could look into gaping the rings and possibly adding arp rod bolts.

I guess what I'm wondering is how much of a straight forward swap is it? I'm sure physically it'll be no big deal, but I've read that there's a difference between the reluctor wheel?

I'm not sure what all the little differences are. Would there be any problem controlling it with my 2000 ecu? I have HPTuners and am planning on learning how to tune for myself.

I like the idea of just pulling my stock engine out and storing it. That way I have my original engine as a back up.
