As I was filling the cooling system I heard and then saw coolant coming out of one of the threaded freeze plugs. I figured "okay, I got those." I tried a 1/4" NPT plug and it wouldn't thread in. Does anybody out there know what size thread(s) the threaded freeze plugs are on a stock block 351W?
Also, I have been trying to figure out the thread size of the timing cover stud. I tried 5/16"-18, 5/16"-24, M8-1.00, and M8-1.25 nuts without success. Not critical, but a convenient place to run my battery ground.
