305 tbi on 4.3

[dollarjim]

will a 87-91 5.0 throttle body fit a 90 4.3? Would like to say TY in advance for any and all help.

Yes but you need the 4.3 injectors.

Yes the 4.3,5.0, and 5.7 all share the same T.B. but with different injectors, but a lot of87, 88, and 89 models have a different designed TPS sensor, and the plug is different, although the wiring pigtail can be cutoff and swapped though.

Thanks for the info. Stripped threads in tb and found 5.0. Im an old shade tree mech from the 50s (flat heads and 265s) this new stuff is all strange to me. Got an old truck and since my wife passed Im gonna start wrenchn again. Thanks again for the info.
