I forgot to update this since I started a thread on LS1tech about it. I've found out that anything over about 7500 rpm would atleast double the cost to build it, so that's out of the picture. With a 4.8 crank and a 7500 rpm limit, the piston speed would be slowed down to the point where stock rods with ARP bolts should be adequate. I'll be boring it to LS1 bore size- 3.90" to unshroud the valves and have a better selection of off-the-shelf forged pistons.

Here's what I've come up with so far.

Aluminum block L33 5.3, LS1 bore and 4.8 crank. ~312 CI
Stock rods, ARP bolts.
Forged rods if needed.
Forged pistons.
Solid roller lifters.
Shaft mount adjustable rockers.
Double roller timing chain w/damper.
L33/799 head castings, C5 Z06 hollow valves. Send off for CNC porting?
Self built IR intake, four two barrel weber/dellorto carbs.
Hooker cast iron headers- should be fine for small CI- I want the retro look of them.
MSD LS1/LS6 ignition controller.
Drop in trap door/baffled windbags tray.
Possible fabricated/weld on wings on sump for higher oil capacity.
