1985 D150 440 Before and After...

What all do you need to change to make it a 440? I would like to do the same with mine.[/QUOTE

It was a pretty easy swap actually.. Did have to get a smaller brake booster from a factory big block truck.. This truck had a 904 from the factory so the driveshaft was too long.. Also had to make some changes to engine wiring harness too.. I cant think of anything else we had to change...
