I need to know what the difference is between the 90/90 and the 90/92 ? I'm going to just skip the LS6 and go with a FAST and was wondering what the better one for me would be. I'll have ported heads and a nice sized cam with full bolton's along with LT headers and true duals. It will stay a 346 for now until I stroke later down the road with a fully forged and balanced rotating assembly. What would you guys recommend and why ?

If you are buying new, you can only buy the 92. From what I read, they are so close in performance it won't matter. So if you can buy a used 90 vs new 92, go for it.

The FAST 90mm throttle body had some sticking issues, but they redesigned them on the 92mm throttle body to fix the sticking. YOu can find some really decent combos on ebay with a new 92/92 combo.
