1968 Plymouth GTX

Rod bearings came. Got four pistons installed so far.

Making progress. Heads and intake manifold are ordered and on their way. Also ordered a Carter M3672 fuel pump. The old pump was broken in half.

Once you get it all together, check your fuel pressure early on. I went through three pumps before I found one under 6 lb.s.
 
Heads and rocker shafts installed.
Test fitting the manifold. Ran out of the Turquoise paint so will need to wait a bit before proceeding.

Valve covers are just sitting in place. I have had these in storage for over a decade. Thought now might be a good time to put them to use.

Heads painted, fan and pulley installed. Still waiting for new parts to arrive.
Also, it turns out my Holley 850 is so old that Holley doesn't even list parts for it on their website. I emailed them and they said I had to call and speak to an order specialist. LOL

Ended up reusing the alternator brackets as the one I ordered from 440 Source didn't fit.

Alternator is installed but I don't have a belt so it's sitting in place.

Order a new power steering pump, not realizing that It didn't come with a cap.

Did the engine have two fan belts installed? Right now it appears everything is aligning with the rear groove in the crankshaft drive pulley.

Which brings me to another question. I found that I have two extra drive pulleys. One is like what I have on my engine measuring somewhere around 7 3/8" with same size grooves.

The other is about 6 5/8" and the inside groove appears smaller.

The bolt pattern and center hole are the same.
Any insight into which one goes with what engine would be helpful.
 
2 belts, 1 around the PS pump and crank pulley and the other goes around the alternator, water pump pulley and crank pulley.

I just installed the new power steering pump and pulley but it doesn't line up with the front groove on the drive pulley. Its centered on the front lip of the drive pulley rather than the groove.
Is there a way to adjust it? I tried loosening the bracket bolts but it didn't change much.
 
Amazing how many modifications and problems you find in the wiring on these old cars.
Here they put a jumper cable to bypass the ballast resistor. There was a similar one behind the dash that eliminated the panel light switch.

Removing the harnesses from the firewall connector. The top one is for the wiper motor:

Next is the voltage regulator, washer pump, horn side harness. Note the fusible link:

A couple of splices and dead ends in this harness:

The final connector is for the headlight harness. Notice the yellow lead running to the relay. It is attached to the plug by one single strand of wire:

The connectors for the dimmer switch, console, dome light, trunk and tail lights is behind the driver side kick panel.
Of course all of these are wrapped with tape and labeled upon removal. You end up with a box full of wiring harnesses.

When I did my GTX I went ahead and ordered all new wiring, simply bc the internal wire just became so brittle
