From What I have read every chris craft motor was a side oiler casting. Almost every one of them would be a top oiler design. As said a few came as true side oilers. Most likley becuase ford was behind on production for Chris Craft. So they stole up performance blocks for them. Which could really explain why a lot of shelby's that were supposed to have 427' ended up with 390 and 428's. That is just an Idea and opinion. It does make sence though.

No Matter Which 427 you have you are one lucky dude to get 2 for FREE (virtually). I NEVER have that happen. I will keep my Eyes open though. Good luck on the rebuild.

If you're still looking for 427's I've got two Ford 427's we pulled out of an old Chris Craft. This boat was run in fresh water and the engines were running when we pulled them out. E-mail me if you're interested. Thanks

I'm rebuilding a 427 Ford Marine Engine, for a 1964 XL Convertable. This is the second time for a rebuild and just need some good advice on what to to with this motor. I had to replace a rod, which was bent and the gargage replaced it with a 390 rod. They said this is the replacement for this motor. Only the rod and nuts are smaller than the original. Is this a problem??? When putting the engine back in the Second Time, we still problems with "pinging' and "knocking". Is there any thing we can do to get this motor to run as a powerhouse. $3000 later and the block still sits on the bench in the gargage. Please HELP. Any advice on what to put in this motor (Cams, Heads, Rods, and Valve Springs, Etc.)

First off your machinist is flat out whacked! Sorry. The 390 and 427 rods are the same length and thats about it. The regular 427 used lemans rods with cap screws instead of nuts. You need to give us an accurate description of what the oddball rod looks like. You said the bolts are bigger? This might mean that they used a 428CJ rod in them. I'm not sure about the marine. You can install the bigger bolt in the 390 rod. Did he balance this engine? The 427 lemans rod is a good bit heavier than the 390 rod. Other than bolts there is no difference between the 428CJ and 390 rod. Need more info.

 

Yeah I'ld put all that stuff in. LOL JK Couldn't help myself. My advice is to start a new thread. You will get more hits that way.

The Marine 427's used the original 427 (non Lemans) C3ae type rod. These rods featured a heavier lower section and larger 5/8 in bolts.
Substituting a standard 390 rod for ONE of these would certainly make some interesting things happen in the engine.

Get it out of there and replace ith with another C3AE rod.

 

I just swaped for a set of the 427 marines
what is the diffrance in the cranks Marine to
car? I would like to put one of these in my
66 Fairlane. I have a nice set of med rise
heads and a Ford 2X4 intake.

The marine engines used cast cranks where as (allegedly) R & W code cars after 1965 would have used the steel crank.

The cast cranks are the same as 390 cranks, nothing really special about them

 

some marine cranks are reverse rotation cranks. They need to be reground ot honed to forward rotation for automotive use. I think some Maring vranks were steel, also. But if they are cast they are basiclly 390 cranks.


Scotty

 

What needed honed? I don't see where it makes a difference.

 

As I have never used a marine crank w/reverse rotation I am just going by what I have heard. But the reverse rotation can supposedely cause problems when being used in a standard roation engine. The metal is basiclly folded wrong or something like that.

Scotty

 

I think I know what Scotty is referring to.
The reverse rotation cranks work fine in cars if you have the crank grinder remove the 45 degree slits in the main seal area. Those slits are hold-overs from the rope seal era and are not needed with the modern neoprene rear main seals.
