Hi!
I´m back to working on my dads old car again, its been sitting for a couple of years (got kids, house etc, you know the drill :))
Anyway, the car is a 1968 Dodge Dart GT, imported to Sweden and it´s been sitting in my dads garage since about '91, when he removed the original engine (273), tranny, and some other parts and transfered to a Plymouth Valiant.
The engine that will go into the car is from a '71 Cuda, with 727 transmission, thats been sitting since sometime in the 80´s, and which have also been scavenged for some parts.

I´ve never worked on old american cars, mostly Volvo´s (a lot since you know, Sweden, 740 and winter is always a fun combo) and BMW´s.
Now, the car will have some upgrades like a new tank with electrical fuel pump, HEI D.U.I distributor with built in coil and module, Street Demon carb, electrical fan on aluminum radiator, and some other stuff.
But there are some holes, both threaded and not, that I´m not sure what they are for. Most are probably not important, but I would like to ask you guys if you can help me answer my question so I wont try to start the car and have oil and coolant water all over..

I´m missing quite alot of bolts and nuts that I have to rummage around for, and I have like two pallets of stuff that is supposed to "mostly" be for the car and engine, and also some other cars....

I´m not sure the oil pressure unit is the correct one, and I would also like to purchase a new water temperature unit.
Would these be correct?

Also a little worried about the holes in the bottom of the engine..

Thanks!

? in upper left is the coil bracket along with the bolt just above.

? middle left is an AC bracket boss

Pic 2 correct, ballast resistor. The two wire side goes to coil side of ballast

Pic 5 those deep holes are machine dowel holes for use when the block was being machined
 
Pic 1 top left is coil mount hole, second hole has bolt in it already.
Pic 2 Could be ballast if its an older car with single ballast.
Pic 3 Possibly NSS wire if its an early car. Im not exactly sure what year they switched to the three prong switch, probably around 69?
Pic 4 Yes, correct sender for light. Gauge sender is much bigger metal can.
Yes, coil wires. Should have D shaped hole in the terminals.
The choke well is factory piece, not a block off. However, your missing the top part of it. Perfectly fine as is if your going electric.
Pic 5 Big holes are locating holes for alignment when block was machined. They serve no purpose after the fact.
? hole may be block drain(antifreeze) and would have a 1/4" NPT plug in it.
Other hole is for the support bracket that goes to trans. However, they sometimes wont fit with headers.
Those links look like the correct parts but you can get them much cheaper. Check at rockauto.com .....not sure if they ship to Sweden.

These two in blue are for the coil mounting bracket...

These two are for the A/C compressor mounting brackets...

These two are for the throttle return spring bracket... The bolt hole is where the bracket mounts to and the non-threaded hole is where the one arm goes into to keep it from rotating..

This nipple supplies intake manifold vacuum to the power brake booster...

If you are running manual brakes, plug it with a SAE pipe plug, or replace it with one with a nipple on it for a vacuum gauge if desired...

You can download factory service manuals for free here... Look for the year and make of the car you are looking for...

The wiring diagrams are in the back of chapter 8...

Definitely block drain, needs a plug or coolant might come pouring out. Sometimes casting sand covers it and it won’t drain. Needs a plug. I put petcocks in mine. I drain the water after race season and put coolant in it, gets cold in the garage. Actually thinking about just draining it and leaving it empty over the winter. Oh, be very careful with water pump bolts. You put a bolt that is too long in and it can hit the cooling side of the cylinder wall and crack the wall. Very bad.
