Alrighty, after a brief interruption yesterday (one of those "grrr, this doesn't fit.." episodes), buying some ATF, the need fittings to fix yesterday's problems, I fired it up.
Of course, fuel immediately starts to pour out of a fuel line that I didn't get clamped tight enough. Talk about a panic - open exhaust, raw fuel dumping on the ground.
Shut down, had a neighbor come over to man the ignition switch, and clamped the line. 2nd start, no more fuel coming out.

Of course, the fitting on the power steering pump is leaking.. and it appears the pump is not sufficient to run the power steering and the ram assist. I'll play more with it - it's weird, it turns fine one direction, but it's impossible to turn in the other.
I have one other set leaks to fix on the thermostat housing I made - a couple of pin holes that coolant bubbles through.
After that it's time to make the exhaust flange, finish the front tubing, clean up the electrical, and go play!
