Just about to put the 340 into the car. It ran fine before I removed it for paint. That was about 2 years ago. It's out for paint now so I'm building the engine on the K member along with the trans on a jig that I fabricated. I'm running an Edelbrock Thunder series 650 carb. Yes, I do have a pressure regulator if needed. I like the fact that the base on the pump is clockable in case I have space issues. But if it's overkill let me know. Plus I wanted one that would look good and not corrode. Thanks
