i just need to know if i need to get a new wiring harness when i swap my carbed 305 for my carbed 350. or can i just use the old one?

 

that depends on whether or not you a puting one of those ungodly computer controlled q-jets on your 350, or if it is just an aftermarket carb. if your going to any aftermarket carb (edlebrock, holley, demon, etc), its not going to use any kind of a wiring harness because it isn't computer controlled. just leave those wires unhooked and clean up the engine bay a little. the one problem one might run into however is throttle linkage to the carb and your throttle valve cable if you're running an auto tranny. the tv cable' gotta be set just so, and you may need an adjustable throttle linkage braket (i had to do this on my 305 tbi to carbed 350 swap). good luck.

 

hey thanks and thank god i dont have to do wiring that is the worst part of any car

 

"Ungodly" is defined by Edelbrock, not the stock cc q-jet.
