my 305 injectors from my tbi have a orange plastic around the two poles what the wires clip on two p/n gm 5235200 and my new motor 350 tbi has the same colour tops and p/n 5235279 am i right to say the 305 had 350 injectors.

 

no. the orange plastic around the poles is not what you are looking for to identify. you are looking for the paint marks on the mushroom in the center of the tbi to see what flow rating they are.

i apologize. ive been putting off the injector chart for a while now. ill get it done soon.
