Identify GM HEI distributors 1103237-8d20 1103372-8k10 1103465-2g8 1112880-5g30. Will any of these retro-fit 1963 Impala 327-300hp?

Answer 1

any Chevrolet distributor big or small block will fit, if it has one wiring group comming out of the dist. if there are 2 separate groups of wires, these are for computer controled vehicles. and will not work. you must run a new 12 volt wire from the ignition switch to the dist. the original wire is a resistor wire and will not supply enough voltage to power the new dist.
