Replacing the 223 with a 390. The 6 runs ok has a nice side/waterfall air cleaner, brand new pertonix ignition, good 1904 carb. Buy the air cleaner, ignition and carb for 250.00 and you get the engine for free. Also have some additional 1904 carbs (may need cleaning or a kit) and glass fuel bowls available.thanks Located in south west Virginia.
