There's no shortage of 340 blocks out there. Granted, many of them are at least .030 over but you still see std bore ones for sale. Not to mention everyone that has horded them (myself included). At some point I will decide that I dont need to keep all these blocks.
I remember the MP "resto"...
73 wheel is different. Should look like this one....

The factory joints had metal bushings. Most all (even MOOG) new production joints now use plastic in them. Yes I believe that bushing moves around in there. It wont move much on a new joint but is noticeable on one with miles. If there is no slop in it, run it.
It looks like there is already a heli coil in the other hole. Someone probably used bolts that were too long and cracked it. A thread sert would be more than sufficient to repair that. Yeah, heli-coils are awesome but on something like that I would use a solid thread sert.
Do they repop these? They didnt when I needed them a few years ago. Yes, the originals are almost always cracked at the front edge. It took me forever to piece together a perfect set. I have some black ones but probably none that are perfect. OP needs to let us know what kind of car they are...
Disconnect wire at the sending unit and see if the gauge still reads full. If it does your sending unit wire is shorted to ground somewhere. Not a common problem but its possible. My guess would be an issue with the sending unit. The new sending units are garbage. I gave up and just keep track...
I dont think anyone has messed with the stamping. That stamp looks 100% correct font. Post a better pic of the casting number. The 340 used 360 heads the last couple years so that is normal. Did it have a windage tray in it?
In a pinch you can use telescoping gauge and calipers to measure the...
I like the taylor wires a lot for budget builds. For my more expensive builds I run the low resistance MSD wires that you cut to fit. I like the fact that I can make them fit perfectly. They come with a cheap crimper but I have the nice msd crimper that produces factory quality crimps.
