New motor in and runnig again.. Yes again.. Made the big mistake of not running a colder plug with a high lift cam. and over the 2000 miles of run time I had developed hot spots on piston surfaces which eventually led to a violent detonation.. yes booom. #1 rod twisted and broken, cam broken, timing chain gear broken and sent through the side of block. I was on it good to when it happened. Had motor out and at the builders on the next monday. 3 weeks later new shortblock ready to go. Took the time to have the headers ceramic coated. and built heat shields for the carbs. I was having major issues with fuel percolation withthe amount of heat that headers were kicking out which may have cause of fuel seapage into the combustion chamber..
