I have a 92 firebird swapping 305 to a 350 carbed, can i bolt the thottle body bracket from the 305 to the 350 and the distributer looks like it had wires coming out the sid but doubt it its a 78block got a new dist cap rotor and coil and hei plug will the tach wire work and what color is it off the motor, any links u can give me would be great.

There's a tech article about carb swaps - that explains the wiring from the cc distributor to a vac-adv distributor as well as the other issues that need addressed https://www.thirdgen.org/carbswap

can u tell me the color the tach wire is forgot to label it? Also missing the bottom 3 wires from the dist that plg in the cap are they essential or can it run with just the batt and tach connector

It's all in the tech article, just read it.
