I have a 1986 chevy k10 350 carb and TH 350 and I want to 454 carb swap it. What will I need...Will it bolt rate up. can I use stock wiring harness.

I've never done a 454 swap but I have heard that everything should fit right in and line up the same.

it will drop right in and bolt up wiring will need a little work oil sender is in a deferent place on the big block then the small block fan shroud may need trimed as the 454 is longer so have fun and good luck
