Hi, I have a 318 currently with a TBI system, as well as a 38 with what I think is a 2 bbl, stock carb. I want to put a 4 bbl on to replace the TBI, which is a 1988, but I was not sure if it is just a bolt on, or if the intake manifold needs to be changed. Is this the case? I know there are electronics and such that will be different, but will it fit? Thanks.

 

in order to put a carb on a tbi engine you would have to change the wiring harness under the hood and change some parts, distributor, coil, intake manifold and mabe a few sensors. you would also need a fuel pressure regulator for your electric fuel pump.
