Post pics, we need to see what you are seeing, it does sound like the unibody and or hood are not in their proper shape. I would try to get the hood sitting flush with cowl and fenders and then start working on the hinges, there's lots of tweaking that can be done to the hinges and because some of these hinges are quite worn you may have to enlarge to mounting holes so the hinge unit can sit farther down than normally. Also the 8 hex head screws that hold the fender on in the gap between the fender and hood are not a standard M6x1mm, The head is not as tall/thick as the rest of the M

This^ and if you are concerned about possible warping then you can do a couple of small spot welds, let it cool or cool it off with compressed air, then do a couple more never letting the pipe get too hot, then grind it back down.

Do you know if the rear wheel bearings were changed during the rebuild? Is it a continuous sound that is consistent with the speed of the car? Rise or fall in pitch?

Get a set of the NGK's and try again, white smoke is often coolant getting into the combustion chamber.

You need to find out if that is actually happening, get a friend to crank the engine while you take a voltage reading at the pump.

As long as you can use that gas in the mower then you can think of it as free😀

I notice you have mounted the rear spoiler nice and tight to the hatch, that means you will get some vibration rubbing on the rear quarter panels where the spoiler over hangs. The way to prevent any scratches before they start is covering the area with a small piece of the 3M clear film. I only discovered that after the scratches had happened on mine.

That's a nice setup.👍

Can't say I have ever seen any, I think most of us go a place like McMaster/Carr or Fastenal.

WOW, I can't believe it! Where can I sign up for this amazing offer?

Yeah that's a little bigger than normal for these cars but as long as the fuel regulator is working properly once the fuel rail fills up it will have proper pressure. Maybe turn the key to ON and just let the rail fill up before turning the key to start.

If you're putting a swapped engine in you might as well start from scratch, you'll be glad when it's done that everything was set up properly in order.
