IMO, to me it doesn't matter what year I would get. Most ppl prefer the 2001+, becuase of the ls6 intake and slightly higher HP rating.
But, you are not worried about the intake cause you only want a longblock, no intake.

True, but if you can get a 01+ LS1 that has the LS6 intake, you can sell it for $300+ and off set your cost. The regular LS1 intake is almost worthless. Just thought i would throw that in for free. Oh yea, 1st post 
edit: oh yea, How much HP can the stock 5.3 or 6.0 truck style TB support? i was just wondering, since the LS1 guys port/polish their TB for a few extra ponies, is there anything like that for the truck motor guys?
