Got half the day off and finally got it somewhat finished up:
Mounted the radiator, mounted the trans cooler, cut and assembled new hoses, installed the upgraded hydraulic pump coupler, adjusted the left brake band so the foot brake is more even, machined down the mounting ear on the new alternator so that it fits, new fan belt, welded up the exhaust a little so that it doesn't rattle and finally filled it with some coolant which is where things started going down hill.
After topping it off I noticed the hose between the timing case and the pump housing was leaking... no big deal, the worst part was when I noticed the block had a big(ish) crack near the fuel filter housing. My heart dropped..... thankfully im all out of Fu#*s and ill just braze it tomorrow lol. I did get a chance to drive it around the property before noticing the return lines on the injectors were spewing fuel everywhere. Fixed that and it quit running, so I reversed what I fixed and it ran fine? Looks like I need to investigate the return line being clogged. Other than that, the transmission was pretty weak, probably low on fluid. When I had the cooler taken off, I touched the fluid coming out and had a smell... it was gear oil. A full fluid flush is in order.
If anyone ever has to make some 300psi or lower lines, use push lock lines and fittings, they are magical.
