First time out driving since the race and notice a knocking sound from the engine. Checked the rockers and springs, they look fine. I'm guessing a rod is knocking, probably pushed it too far with a stock GM crank and hammered the bearings. Looks like time for winter hibernation and start saving for a good 3.622 crank. 
I say do a Dragonslayer 4.0" in your block, do Ultra HD rods and Wisecos... Make it a 383 so it will make some torque...
Or do it LS1tech style where stock 5.3s make 1k rwhp reliably for $500 and last forever...

It's actually not that bad, but should freshen up before running on kill again. I have a spare LS6 block to build so could just be an R&R when the time comes.

the ERL looks great but holey shmokes it's pricey
I'm going to try a 4.8 with either the stock short stroke or a 4.0 lunati crank. I'm a bit undecided on going short or long stroke or even staying with the 3.622 crank.
the l33 alum block looks good too.
I think the short stroke crank might hold up much better under load (even being stock).
if you need a 4.8 motor, crank or rods, or anything let me know.
I've got a pile of them and I need some cash to build my motor so they will go for a good deal!!! PM me if interested.

The core is the rub on the ERL. The six bolt superdeck is $3650. An LSX is ~$2550. But the LSX still requires machining whereas the ERL is good to go. I spend ~$1000 on machining my LSX so it's pretty much a wash. But without a donor block for the ERL you pay another $1300 core charge.

I'm pretty stubborn but I think a 4.8 with head studs on E85 will live at 900 and I hope to prove it.
might do it with an L33 block as they seem pretty durable too.
anyone try the LS Next? not sure I like the block design but it's priced similar to the LSX
I've thought about just getting the 376 B15 crate motor as it's quick and dirty but I'm scared that the powdered rods might fail.
but based on the LSA motors in the caddy getting some big HP out of "stock blocks" it might just work. those long blocks have the nice 6 bolt GM LS3 heads that flow well. but it's still a bunch of $$$

The LS Next has some neat features. But it requires an oil pan rail adapter and external oil filter. Not sure if it comes machined either. Also comes in iron or AL.

Decent info on the available aftermarket blocks:

It's good to do your research and find out what it takes to put the LS Next in a C5 corvette and also some of the other specifics on the other blocks.
The 4.8 should live, but how long will it live and do you have enough turbo to get to 900 rw?

Why not keep it simple and do a forged LS2? Your car runs **** right now with not many fancy parts in there. Wouldn't one of them high dollar blocks be over kill for the TTi kit?
Or you are secretly thinking of that new twin kit with T4 turbos?

I'm with ya on the lsx being the bang for the buck block, however, if I could do it again, I'd definitely stay aluminum, merely for the improved heat shedding... Oil and coolant temps are much easier to control with an aluminum block...And an aluminum block is easily 150lbs lighter then an LSX. Takes another 30-40hp minimum to make that up.
I'm sure Chris' LS6 is still likely good. I'd just throw a 4" crank and rods in it and back together. His turbos/exhaust/etc etc are just about maxed out anyway. No reason to get crazy.

I actually just installed a lsx376B15 in my car about a month ago. The engine is about 130 lbs heavier than my forged ls3. I also put a Dewitts rad and fan in the car. I typically see 180-190 degree temps.
It was a quick and easy install. My car was down about a week. It was an easy decision because my machine shop was backed up about 8 weeks before they could look at my old engine. It was pretty cheap ($7800) compared to my 416" forged ls3.
