RE: Drilling a 427 Marine Block

Thanks for the link, 68S-Code, ... I was looking through the forum archives last night and came across this statement:

"The motor mount bosses on marine blocks would logically be flycut prior to boring, honing, and sonic checking the blocks, therefore 427 marine blocks would necessarily be "predefined" as marine blocks, not selected due to core shift, or whatever. Marine blocks apparently get their motor mount bosses flycut on the main FE production line - a line that destroys the side oiler passage to the extent the block can only be drilled as a center oiler."

This, if correct, would indicate that these marine castings can not be drilled out after the fact as side-oilers. I will contact Gessford for additional information.

This thread, so far...
