Have a Chevy 400 small block 330 horse 245 at wheels what size jets needed in a 650 holy carb not a double pump carb

SOURCE: 383 SMALL BLOCK CHEVY

383 is a modified engine...since it's not stock, you need to learn to "read" spark plugs. In reality the # used in any engine is a starting point for experimentation. Begin with factory plug, If too white or too black change heat range 'till you find a # that gives mostly white porcelan with light tan tinge. That will be a good plug to run.
