is there really a big difference in the part numbers for the 350 TBI throttle bodies? I see several part numbers but they all pretty much look the same? is it the shape of the sensors or something?

and yes, I'm asking out of ignorance. case in point. I just picked up a 350 TBI unit part number 17087100 that shows to be 91-95 but yet shares the same part number with several others...

its not this particular one. just that this listing on ebay shows all the cross references is all. they are all pretty much the same right?

also, in case you were wondering, dude just kinda tossed it in for free. I bought a pair of 454 TBI throttle bodies for $100 and he just threw the 454 intake manifolds at me and this 350 throttle body. I believe the 454 manifolds are the same as the mercruiser ones so yay to that, I can resell them to the boat guys. I should be able to maybe put the 350 injectors into the 454 throttle body and tune the ecu accordingly as well right?

dont ask why, thats a conversation by itself.
