Throttle Body differences.

I noticed that bbk shows 1 throttle body for 92-93 LT1 and a different part no. for 94-97. What is the difference and are they interchangeable?

I don't know about BBK's TBs but there are differences in the stock ones from year to year. At least according to David Koldos who rebuilds/rebores the OEMs out to 52mm. From an email exchange I had previously with him on the topic:
"...[other model years] will bolt on your plenum fine but there may be a difference in the throttle linkage. Some Vettes used a fast open profile throttle cable cam, others used the more common F body more rounded cam."

Hope this helps...
