I started the coupe today. Here's the unedited video of the first time I pushed the starter button. For the full experience, be sure to view this with good speakers and the volume loud enough to make small children cry. (Luke cried.)
It didn't want to idle, probably because the timing was way off.
It almost didn't happen. When I filled the motor with coolant, it just poured out the back, coming from between the intake manifold and the head. So on Saturday, we pulled the intake manifold and it became obvious what the problem was. The heads are 289 heads, but the intake is from a 302. The 289 heads are actually a little bit shorter than the 302, with narrower water passages. The result is that the water passage at the rear of the drivers side actually overhangs the rear of the head!
So I used some J B Weld to narrow the water passages in the intake, new gaskets, and plenty of silicone to make the seal. But when we got it all buttoned back up, it still leaked like crazy. I had managed to get a wire pinched under the rear of the intake. Doh! Pulled the intake again (intact) and replaced the gaskets again.
In between, I also wired the dash, tightened up the wiring under the car, attempted to set the timing, and did a million other things.
I have several issues to resolve. There's a tiny fuel leak. The timing is way off, or perhaps there's some other reason why it would barely idle. And the battery is junk. (It's the donor Mustang battery. I didn't want to buy a new battery until I was ready to use it.)
