I dropped the pan on my 65 comet and am surprised to see that there are only 4 main bearings. Is this an anomaly? i have 5 frost plugs and three bolts on the water pump. I used my calipers and the bore is 3.68 actually closer to 3.69 but I have cut the carbon off the top and its hard to use calipers but I don't have any inside micrometers. Was there a 200 with only 4 main bearings?
