I don't know much about it. Bought it being told it was running good when parked. The truck was parked about 4 years ago because of a busted radiator. I hooked up an IV to the carb, threw a battery in it and it fired right up! Idles nice and revs good. Its a little loud since it needs some manifold gaskets. I have a video i'll try to get you of it running. Better yet.....road trip up here and we can run compression etc.
