We cranked my 351w tonight for the first time. It took us a minute to set the timing right and get it to crank but it did. We begain to break in the cam and about 3 min. into the break in, the entire header begain to glow fire red. it looked like a hot coal that just came out of fire. we immediately shut it down. what could the problem be. any help would be great.
thanks
