Gears & Axles - Beeffing Up My Tranny

I have a 98 vette with an M6. I just blew out my clutch and replaced it with a Mcleod dual disk. This clutch has unbelievable grab. I wanted to start upgrading my trany so that it can handle the power. My car has 607rwhp. What trany upgrades are there for the M6. I have the stock 3.73 rear end. I do not want to go to 3.90 or 4.10. As it is right now 1st gear is all tire smoke so I cant imagine what would happend with 3.90 or 4.10. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

Oh by the way Iam not to worried about the cost Iam just looking for some solid Ideas and detailed info! Tanks in advance.

Looking for some advise? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Only upgrade I know of is steel shift forks but they aren't making the tranny any stronger. You could have all the parts cryogenically treated I guess.

I've seen 2 M6 Corvettes rip apart output shafts which took out the tranny and rear when they broke <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
