    Is there any difference between a 305 and 350 TBI?

    Yes. 45 cubic inches.

    I believe the only difference would be the injectors and the chip.

    <font color=blue>I think he means the EFI, not the motor it sits on. I dont think there is any difference between the two

    So I'd need to swap injectors and the chip? Is this for sure, or a guess? Maybe it's time to make a call to Howell or Turbo City or someone similar.

    I am pretty sure that they're absolutely identical.

    I know that 305 TBI will work on a 350 because my friend just got his '91 K1500 swapped to 350 when it used to be a 305.

    I'm certain they would be the same. Call your local GM tune up tech and ask him.

    If you are having too much fun it's probably illegal.

    They are the same all the way through. There was a post a few months ago on this and after consulting some better sources, it said they were same. LOL.

    If you ain't hurt, you ain't playin' hard enough.

    Will the distributor from the 305 bolt in fine on my 350?
