"A couple of comments about the Ford 427 marine motor.
Firstly, you can not repower your boat with GM motors by selling an old Ford 427. The blocks are basically worth $1500 to $2500 MAX and I don't see any equivalent new GM motors out there in that price range. They are now making new 427 blocks (Genesis is doing it for Ford Motorsport).
Secondly, Summit Racing won't know much at all about the Ford 427 marine motor. I wouldn't go there for anything.
Thirdly, parts are available, they are somewhat more expensive than GM counterparts, but people are rebuilding these motors every day. Many of them still have original cross hatching on the cylinder walls, so be careful that youre not rebuilding something that really is still in good shape. Toss the points and go with Pertronix ignition, it is the best thing you can do for a vintage motor, and the big Ford will NOT run well if the solid lifter valves are not set properly.
Here is a site and forum that can help with the Ford marine 427. See the MASTER INDEX for lots of scans, trouble shooting info, etc, and GOOD LUCK. I'm running two of them now, and they perform great.

It is true you can find Ford 427 motors out there selling for $10,000 and $15,000 but those are the ones with all the machine work done, with special internal parts, and lots of EXPENSIVE racing parts. By contrast, the marine 427 uses generic 352 and 390 heads which are good but not high performance, it uses generic pistons, a cast crank, a truck cam, a very restrictive 80-pound cast iron intake manifold, and low compression pistons. The result is a great marine motor, but nothing an automotive buff would be able to reuse, except for the block, and perhaps the crank. The heads can be reworked, but that's throwing $$$ at them. The 427 marine motor should be retained for marine use, IMHO, as it's a rare and great performing piece of equipment. The blocks are really the main attraction, cross bolted, and high quality iron.
