If you change your 305 to a 350 in your K1500 with an automatic transmission will the wiring hook up exactly and will you have to change the computer chip?

Yes your wires will hook up and no you wont have to change the chip either.

the wires will hook up but if it is a tbi you do need to change the chip or it will run lean because the timing of the fuel dilivery for the 305 is longer than the 350 and you will run lean so the chip needs to be changed to change the timing of the pulse.
