Finished up graveyards this morning so I started to get the engine ready for cleaning and painting. Dropped the pan and found some metal. Main brg. 2,3 and 4 didn't look good. Took it to the machinist and had it checked. The crank is cracked. Looks like the MATS will have to wait. I questioned the cracking since I do not race and he told me that it was probably fatigue. I've been driving it for about 7 years now with no issues. He told me that they don't last forever. Looking at the 440 Source crank that is pre-cut for the 451 stroker application. A used crank plus machine work is about equal to the 440 Source one.
