390 Problems
I have a 75 f250 with a 390. When I bought it, it had a 350 holley carb on top and a motorcraft in the toolbox. Both need carb kits and the motorcraft seems to be at least 375 cfms. Wanting to know which would be better because this is gonna become a play toy as soon as its running, also need the firing order since the intake has been switched.
