Thanks MAS, if it sticks I'll go NW without any delay. I have my WB now so when the intake goes on I will go SD and kill the MAF. All will be 4".
I remember reading about the sticking and problems with the fulcrum moving on the shaft. They assured me that the problems had been fixed and I recieved a new revision TB. They flatted the shaft, but that's the only thing I could see that they have done on the TB. I'm going to warm it up to like 180 degrees in the oven and check it again.
DaEvil, I cracked my LS6 intake. That, combined with the fact that I'm going to go 402 I decided on the 90mm fast.
If you want to try to fix the LS6 you are more than welcome to it. I bought it cracked (paid 35 bucks) and repaired it. But after about 6 months of heat cycling the repair broke. I am just going to toss it so let me know if you want it, just pay the shipping.
