440 marine block - 08/10/12 11:57 PM

are they any stronger than a older block?
anyone have one apart at all? are the mains thicker
like some of the 6630-440 late blocks.
i got dibs on one for 500 bucks

no different than a std. 440 block so don't let the seller FOOL you , but I would ask the type of cooling system it had , heat exchanger or RAW WATER , if raw water and it's been in SALT WATER ...

I don't know the current going rate... but $500 sounds like a lot for a 440 block.

it is a running long block. i said 500 for me may not be a good thing cause i split a stock 73 block and will end up throwing everything away but the block and caps. i got the sholder shrug so this will not be for me. just wondering if there is any strength differences. it is a forged crank though.

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

I know you're after the block but if it is RH rotation the crank knurling at the rear seal is not gonna work for you.

yeah that would be funny not catching that and have it pump oil out>

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.
