A guide to GM twin blade TBs from the mid 80s to the mid 90s

This video goes over some differences in GM TB units. These are from an LT-1, Typhoon and an L98 if memory serves right There are a few significant points if you're swapping these to different intakes that must be addressed. Among these are the idle air passages, the linkage and the TPS/IAC wiring. Overall a bit of work but not bad and it may help your swap at some point.
