I am in the process of assembling my rebuilt 261. The crank and cam are in and when I started to install the journal caps I noticed the middle rear cap that has the thrust bearing is higher on one side. No excuses, but somehow I missed this when disassembling the engine. I am not sure if it matters which side the higher part of the cap is oriented towards but I suspect the cap is lower on one side to accommodate the oil pump pick-up pipes. Incidentally, the engine was harvested from a 1960 Canadian Pontiac. It originally had hydraulic cam and lifters but the rebuild will be changed to mechanical. Any advice will be appreciated.
