I decided to pull my motor and up the compression on my LT1 383 blower motor and found it was going to cost more than I was wanting to spend. The motor is 9:1 compression and I wanted 10:1 but milling the heads and doing the thinnest gasket would only get me to 9.5:1 so Im selling off my LT1 parts and going with an LSX block. The block has a few issues (listed below) but everything else listed is in good mechanical condition per machinist.
Some of the parts are still at the machine shop so pics will need to wait.
See my post on ls1tech for more pics

LT1 383 short block dissembled $2000:
Will come with 4-bolt block .030 over, 0 decked, 6" Eagle H-Beam rods, Eagle 4340 Forged crank, ARP studs and rear cover. Motor was 9:1 with .040" gasket and 55CC heads. The motor made 368 HP 355 Torque NA and 610/600 with 14#s, all with blower cam and 4l60e and 3:42s. Not bad for low compression. 11.7 in 1/4 NA, never got a good pass in with blower.
When motor was tore down it had 3 cracked main caps and one spun bearing. You would need to relinehone mains, new bearings and rethread all oil pan bolts too. It bassically needs a rebuild and the oil pan bolts/ main caps. Everything else listed above passed inspection.
I am willing to separate the rotating assembly from block if someone does not want to put the money into it after a week or two if it does not sell. Willing to ship if buyer pays. Old pics below, parts at machine shop.

LT1 Fuel Rails for running Parallel fuel system $125:
Just got these welded up with -06AN fittings before I decided to sell my stuff, never ran welded by pro. See pic below to see how it will look on an intake. might need to shave off 1/16" off intake at crossover section to clear 90 degree fittings, will not hurt intake performance.
