LT1 Throttlebody
What are the differences between the 90-92 TPI and LT1 throttlebodies? I know that the way the TPS is mounted is different. Could a LT1 throttlebody be modified to work with the TPI TPS?

TPS and IAC are both different. I don't see a reason why you can't make it work. You will need to use the appropriate coolant plate (lower half of the throttle body), as it is different from a TPI car.
Now that I think about it, if you use a TPI coolant plate, you can use a TPI IAC valve. So the difference would just be the TPS.
