Well i finally got around and bought a thermometer, and put it in the radiotor. and it only read 190 maybe little less. The gauge was 250. So i guess it is the gauge. But how bout the glowing orange headers?
no, i have bbks and they NEVER glowed....But as an idea, check your spark. I had put my brother's wires on wrong on his fox stang, i had used a non-ho firing order and it ran like crap and the headers glowed.
For you, if its not that, then certainally check your timing.....then your wires coil and plugs, because it seems you may be getting unburnt fuel into your headers?.....Or maby its a lean condition.
