OIL Gallery Plugs Top Oiler

I am having trouble locating a diagram or someone that knows. I have a need for info on a very specific 427 FE Block. ( Marine Chris Craft Engine)

This is a TOP OILER not Side Oiler. I am attaching one pic to show what it looks like from the back end.

Can ANYONE give me a diagram or description as to where ALL of the oil gallery plugs are located so I can check/install?

The Steve Christ book doesn't even have pics of "this" block in it. If you want to discuss it in detail you can call me at (704) 287-3914. I'm located in NC.

I've heard so many different " well there may be one located....." I have even heard that there should be one that can only be accessed from the water pump port? If you know and are not guessing, I would appreciate a reply.

Well, seeing that it's a solid lifter block, that cuts down the number of plugs. There is one in top/back of valley that feeds down to rear main, the other two for lifter bores should be blank since they aren't used.
The one behind the timing chain(There is a 1" hole behind dizzy to get to it) That is the main feed to rear of block(above cam).
You can see the three at rear of block(two above cam, the other below). The two outer locations at cam are not drilled.

The one BEHIND the timing chain is the fooler. I left it out ONCE! Never again. The rest are pretty easy to locate.
