Actually for drag racing a thirdgen would be more ideal since the axles are shorter. It isn't a huge difference but the shorter the axles the stronger they are and less likely to twist.
Also like Big Als just said, the LS1 guys beat the crap out of their rears, so be careful what you get. I'm partial to my 3rd gen aluminum drum torsen (yes same as in 4th gens) richmond 3.73 rear
. It's got almost 190k miles, the shafts are original, the rest of the rotating parts have been replaced when I did the torsen and gears.
If I were go buy now I'd get a 4th gen rear, that way when I upgrade to 17" wheels I have a larger selection and only need to buy the 2.25" spacers for the front.
