Hey what up guys this is what's going on, a week ago I got my engine and transmission total rebuilt but its been heating up at idle when waiting for the light to turn green, it has a brand new radiator and thermostat. today I drove my wife to work which is 40 miles round trip I noticed it was getting hot so as soon as I exit the freeway and start driven on the street it gets even hotter and its running like crap I lose power and trany feels like its slipping. well I make it home open up the hood and my headers are glowing red hot. I'm thinking cats are plugged but not sure. what do you guys think it could be. I would appetite any help and thank you in advanced.

 

Appreciate*

 

running lean will cause the headers to glow and the engine to run hot.

 

What makes it run lean?

 

"late"ignition timing can cause the glowing headers too.

 

You guys don't think it could be a clogged converter. I also noticed my exhaust sounds like ****. I guess I'll check it in the morning. timing, fuel, etc. and if that doesn't work I'm cutting the converter out. I would still like more suggestions so please reply. thanks

 

You likely have unburned fuel in the exhaust. Either too rich or retarded timing.

 

A clogged converter could cause it as well but check your timing and fuel first. Cheaper to fix than replacing a converter.

 

Timing

 

Yup it was the converter, couldn't see daylight through that thing.

Thanks fellas for all the help

 

Glad you starightened it out. I thought for sure it was too much timing
