My new Wizard Cooling Radiator- 68 Barracuda

Thank you! I actually got to drive it a little bit today. Still working out bugs such as fuel boiling in the fuel filter. I don't have any sort of insulator gasket between the intake and the edelbrock carb, so I'm trying that first. Next is to upgrade the 5/16 inch line from tank to mechanical pump (3/8"? or 1/2"?). Any other suggestions would be greatly appreciated. I'm already running fuel injector hose instead of hard lines in the engine bay.
