Now I am completely confused as I dig more... hopefully someone will chime in.
I am 100% sure the one you bought is wrong... there are two that I found from that time period for the LT1 which is used on the regular TBI. They are the AC5 and the AC125 depending on the VIN number of the car.
- however, the picture indicates a pin in the housing that the AC5 and AC125 do not have. http://www.skidim.com/prodinfo.asp?number=R084002
indicates the pin in the housing as well.
are there any other markings on your original part? - I really want to find this part.
The AC5 from standard products is for the non dual overhead cam of that the corvette ZR-1 came with.
