Re: The Flathead oil modification thread...
Here is how i did mine, it is a 8ba style block from a '52. Drilled down from pushrod bushing to the rear main hit the center lucky! drilled the bearing insert, pluged the old oil gallery from oil pump (1/4" rod). remove push rod bushing and plugged the hole with pipe plug. This is a Canadian block so install the grub/716" nf set screw in the cross over, has the two vertical holes . 100% filtered oil works real good 6000 miles no issues. Laurie
