I'm really new to Y-Blocks. I have a 59 Ford Fairlane Convertible with a 292.The motor needs to be rebuilt. I have found a 312 marine engine, I want to take the heads off the 312 and put them on the 292.Also want to chane thei intakes want the 4 barrel off the 312. The 312 intake being a marine application dose not have the right hook up for a top radiator hose or tstat housing.Question is do they make an adapter to cross over on the heads or do I cut the front part of the water jacket on my old intake and machine it to fit. Really don't want to reinvent something that might already be in place. Thanks for the help Dave 

Cutting up your old intake might work.   Many marine intakes are of a single plane design which isn't usually the best idea for a street engine.  Is the marine 4 barrel intake a single or dual plane design?
You might be able to find some of these which are used for other marine applications.  Some kind of thermostat housing will have to be found or made.

Check the casting numbers on the heads you already have on the ’59.  If they are both 113’s, then you already have the big valve heads.  Likewise they could have been changed out to a set of ECZ-G’s which are also big valves.  Those casting numbers are located under the intake at the front water ports on the heads.
 
The marine intake fully loaded has two one barrel carbs and is not to be confused with a four barrel intake.  Those one barrel carbs are designed for steady state running.  I haven’t looked at one of those setups in awhile but I don’t remember a provision at the carb(s) for the vacuum advance on the distributor.  Most of those marine engines used a Mallory mechanical advance only distributor so it would make sense there would be no carburetor port for a vacuum advance distributor.

thanks for the info ill look at the #'s on my heads boy am i learning fast 

Charlie and Ted are more knowledgable than I am. But, if you've got a 292 in need of a rebuild, and a 312 with a usable crank, that's a really good starting point. The crank can be turned down for the 292 mains, and you've got a 312 stoke, plus the overbore on the 292 block. If the crank is really good, and the block sonic checks, you can do a stroker up to 340 or so. Even if it's been turned, 320 is possible. It's not cheap at this point, as you're looking at custom rods, pistons, etc. Go have a look at John Mummert's site, http://www.ford-y-block.com , and look at what he's got. You might also take a look at http://www.eatonbalancing.com/blog/ , an excellent source of y block info.

You don't say, but are we assume the 312 block is damaged or corroded to bad to use?.. If it's rebuildable & your 292 needs a re do, rebuild the 312.
