All the ones I've seen were just production blocks... different boat companies use to buy a quantity at a time from what ever auto company would sell them the cheapest price.... and some would change brands during the season build... my boat(Searay) has a ford but most were chevy

If you split a stock block it's probably time to just pony up for a REAL block and be done wit hit . Contact Keoleno for a good lock deck block.
