Have to stamp XE on it in a few places for the premium loot factor.

While I fully anticipate it to be a cast unit , it had a different look to it than I have previously seen in many other 312 engines that I have disassembled.

It is a look that I couldn't quite place,as in maybe a different amount of counterweights.

If its a steel unit my preference would be to build a seriously super engine. Not sure what I really will do BUT no sense in counting any chickens before they hatch.

I"ll post up the final verdict

From what I can gather, Oldmics, if you've come-up with a forged 312 crank, you can likely advertise viewing hours with a donation required for the privilege.

After the viewing hours have run their course, the crank could be offered on eBay.

Using some old barn wood, square nails and the lettering / numbering stencils I've got, we could make-up an 'original' FoMoCo shipping box and label it with the part number CITE 6303 $FX$ I'm not sure what the eBay reserve should be set at...

I bet it would cause some crazy bidding... and you could retire to the land of 86 degree wind chills that you're enduring today. Rolleyes

The only reason 312's exist in Canadian trucks is that the Ranchero's and Sedan Deliveries are licensed in Canada as a truck not as a car.

Its an ECZ main capped engine. That much I did inspect.

I knew about the casting lines on a cast unit but also had heard of the differences in the counter weights which I wanted to understand.

Once I get home I will see exactly what I have.

Frank:

There have been rumors that some Canadian 312 '60 Mercurys had forged cranks. I have never seen documentation or that though.

Crank is still in the engine.

Well, it's 6 below here with NO wind chill, but I'll write you anyway, John

WHEN you get home, check the main bearing caps. Letters are on the top surface of the caps between the bolts. EBUs are 292, ECZs are 312. Smile

Crank is still in the engine.

The color differences explained are difficult to ascertain since everything inside is a grey color.

Worst part of this mystery is that I pulled the pan off the engine the night before I left for vacation (in a wonderfully warm place).

So the answer wont be revealed for another 3 weeks once I get home - Sorry gang!
