I was putting the install of the carburetor off because I was nervous about my float settings and adjustments. Finally, I decided that stuff could always be adjusted when it's on the car so I threaded in the carb mounting studs and slapped a Fel-Pro gasket against the intake. The spacer plate and PCV hose was dropped on followed by another gasket. I threaded the choke heat tube onto the choke housing of the carb and placed it on the studs being careful to insert the lower heat tube nipple into the passenger exhaust manifold and fitted the choke cold air tube to the top of the carb. The upper heater hose was fitted stuffed into its clamp next to the choke housing and the throttle linkage was hooked up to the throttle control. I'm using my original AutoLite 2100 throttle spring and bracket but will be getting the correct parts later.
Finally, to complete the engine build, the distributor wires were routed to their appropriate spark plugs.

All that work on the transmission cooling lines is wasted if I don't have something for the transmission to do. Something like, I don't know... maybe spin the rear differential? I went to the shed and dug out my old drive shaft. I don't know much about drive line lore except for this; a 68 Mustang with a 289 driving a C4 and sporting a stock 8" rear diff uses two different u-joints. The front is a #429 and the rear is a #430. The front (429) has 1 1/16" diameter caps whereas the rear (430) has two 1 1/16" and two 1 1/8" caps.
The rear of the drive shaft is the end with the rubber isolator and the smaller caps (1 1/16") of the #430 u-joint are pressed into the drive shaft leaving the larger caps to be clamped to the rear diff pinion. The front u-joint is simply pressed into the drive shaft first and then the yoke is installed the same way. It doesn't matter which caps go in which part in the front yoke assembly. The drive shaft can then be installed in the car by first inserting the yoke spline into the extension housing of the transmission and then seated in the diff pinion and clamped in. The pinion has ridges on the outside edge that keeps the caps in position so clips are not necessary on the two large caps.

Next, I cobbled together the original single exhaust and bolted its Y-pipe to the headers. It's rusty, leaky, and ugly, but I can't afford my planned dual-exhaust yet so it's going to have to do. I didn't snap pictures because they would just depress you.
I was finally to the point of pouring the first four quarts of oil into the engine and pouring the first 2 quarts into the transmission (in addition to the 2 in the torque converter). The radiator was also filled with a 50/50 mix of coolant and about a gallon of gasoline was poured into the gas tank. I checked for leaks and found a slow drip at the front of the transmission pan. A few strokes of the wrench and it sealed up.
I disconnected the coil and cranked the engine over about 10 times to pump some fuel up the line and to move the oil into the pump to begin lubrication. This was enough to fill the oil filter so I added the final (5th) quart of oil to the engine and topped off the transmission and coolant. Nervously, I called my wife out to witness and cranked the engine over. Nothing. I poured a small amount of gasoline into the carburetor and tried again. It caught, missed, caught, fired, died, caught, and finally fired up... very very roughly, like it was missing on a couple of cylinders. I shut down and went and inspected the carb, distributor, and distributor wires. Whew! I found that I had mixed up 1 and 4. I swapped them and fired it up and she came to life with authority. Clean, with no missing cylinders. WOOT! I set the carb for a high idle, about 2000 RPM and settled in for some serious cam-break-in time. That's about when my wife yelled, "TURN IT OFF!". I scrambled for the key yelling, "What!? What!?", fully expecting to see a fire or something at which point she pointed at the coolant blowing out of the radiator. I didn't put the cap on because I wanted to add coolant as it started circulating. I put the cap on and started it and brought it up to about 2000 RPM again to complete the break-in and it started blowing coolant out the overflow and all over the garage floor. WTF? I removed the radiator cap and placed a funnel I had made out of an oil can into the filler and watched bubbles burp up the funnel and the level would drop and then rise again as another bubble came up. Ahhh... it's burping the air out of the engine block. I just left it to burp for another 5 mins and then topped off the coolant and started it again but this time with the overflow feeding a gallon jug as I fully expected it to occur again until the block was fully burped. I fired it up yet again and held it at it's 2000 RPM for a good 30 minutes with no sign of further overflow (undoubtedly because I was ready for it). My wife then snuck in with a video camera and recorded the less exciting moments of break-in which I will share with you here.
After the cam break-in period, I shut it down, topped off the fluids again, and decided to try to test out the transmission by taking a spin around the cul-de-sac. It was working out pretty cool until I got about 3/4 around and the engine died and wouldn't restart. Evidently, had I used what little gas I put in the tank on the break-in and my hilly driveway and cul-de-sac starved the engine. I had fun while it lasted though. Notice the cool new sequential brake-lights about half-way around. Here's a VMF thread I found AFTER the break-in. There seem to be a lot of tips.
