The aft side of the #3 thrust bearing is torn up, crank is wiped out. Likely was from installing the trans. In search of #3 cap and a steel crank.

Yes but how much of that .100 thou came off of a soft bearing and how much came of a much harder crank?You can see about a .100" gap or more between the crank and the thrust bearing in the main web..... it would be one heckuv an oversize!
I've never had any issues mating the engine to the trans with the trans in the car.....I put the trans in twice, with the engine already installed, a way I've never done before. I've always removed/installed an engine with the trans already installed. Guess I'll never do that way again.
I am a welder and I have access to a nice miller gtaw. Any special way to weld it up? What about filler rod material?
Why not? Don't confuse the materials used in cast cranks with the cast iron used in blocks and heads.... very different.You need to get a new #3 bearing and measure to see how bad it is or not!
Welding a CAST crank is not a good idea..............
It is not cast iron like in a block or head.Yeah welding cast sucks. Someone mentioned welding it but maybe they thought I had a steel crank. On the other hand the weld isn't structural, just a bearing surface that would be machined.
WOW! for some reason i was thinking it was a 360
Shouldn't be two hard to find a crank.......
I realise it is not cast iron,
I have been told that it vary difficult to weld, talking out my arrs as i'm no welder.
so the question is which is more expensive......weld and have machined properly........or find a used 318 crank?????it's no harder to weld than a forged piece .
Not.
If the trans install caused that the trans wouldn't have even worked.
It would have trashed the pump so fast you wouldn't have made it around the block.
Think about this.
The crank thrust surface is made out of steel or cast and made to take some pretty heavy loads.
The trans pump gears are powdered iron and not made to withstand hardly any thrust pressures.
It would have wiped that pump in a heartbeat if the converter wasn't seated in the drive gear.
Also, when you bolt an engine and trans together without the converter seated in the pump it's a very obvious ***** to turn the converter to line up the bolts because the converter is jammed up against the flex plate.
