Sheesh!!! I do not envy engine builders, it most certainly is a love for their craft because the manufacturers shaft them daily. Why none of these parts fit together is beyond me, I mean these people have to grind, fit, re-fit, mill, cut and drill every part. The timing chain gears didn't line up properly so between three sets I made one work but of course that burns up hours we don't have. Not to mention standing on the oil pan to get it to fit and having to fight the gasket that wouldn't fit in the improperly machined timing cover. oh well there's always tomorrow. (Oil pan is on just no picture).
