I found an ad on CL for a 1972 351. Guy said it's a "marine" block. What is the difference between that and other blocks, new and old?
All 351 are good ones. Fastback's" junk" uses a late model roller block.Is a '72 block a "good one"?
Just commenting as I have a casual interest with Ford engine history and I'm bored right now. Most 351 engines used for marine use were Windsors. They were referred to as "marine motors" as well, third parties had a relationship with Ford to make them and Ford made and sold some themselves. There was no difference in the actual block between marine and non marine though except for maybe the type of freeze plugs. The marine designation came from the other marine specific crap bolted on them. They were marine engines, not marine blocks.If the seller says its a marine block, but the ad says a windsor? Find out what it is exactly because its either an M or a W, not both.
The M means 'modified' or 'marine'. Depends who you ask.
As long as you are going to bore it and get better pistons, etc, the yeah thats a damn good block. Just post the casting number up from the block when you get it.Thanks, guys. So if the only difference is the type of freeze plug, is this a good block to go after? I understand that you don't know about the actual integrity of the block.
