383 swap
Hey everyone! So im getting rid of my 305 in my 90 firebird and swapping to a 383. So im curious about the wiring with that. Does anything need to be plugged into the bulkhead junction box at the firewall on the drivers side in place of where the engine wiring harness plugged in. Just wondering how everything else gets power. Thanks!

It was fuel injected. It has the electric in tank fuel pump. I am switching to carborator. And basically planning to buy msd 6AL ignition system

Re: 383 swap
Stuff like that is covered extensively, from every angle in prior threads. You really need to do a simple search. You'll also have much better help if you post this in the carburetor message board. As a next step, review the electrical diagrams at www.austinthirdgen.org
This is the connector on the driver's side of the firewall: http://www.austinthirdgen.org/mkport..._1990_C100.gif
This is the connector from the interior wiring harness to the vehicle's ecm that supplied power and a few other wires depending on options: http://www.austinthirdgen.org/mkport..._1989_C207.gif
And I am going to assume you had a 305 TBI car: http://austinthirdgen.org/mkportal/m...ine_wiring.gif
