Is my carburetor running to rich it need to be metered back to use less gas. or maybe I have a blocked water port in the Head. It get so hot that when I am driving down the freeway it starts to glow red hot down to about four foot down the pipe. The motor is a 292 in line 6 I have gone throw two manifold in one Year. Any ;one got a clue.
Sounds like its loading up with fuel and clogging up the catalytic converter. That means the air and fuel are backing up and causing a heat build up. I know from personal exp. That's where i would start. I hope this was helpful.
