Engine and trans back in. Found out the C4 trans is from a 73, which was sort of a bummer. I was hoping it was original.
Runs awesome. Threw some timing at it, and now it just wants to run. Have a very small tick, suspecting a lifter or exhaust. Going to check the exhaust tonight, and if that doesn't fix it, hopefully a little Marvel Mystery Oil or Sea Foam in the oil will clear it up.
Despite the new radiator, hoses, heater core, etc, I decided to run some Motorcraft coolant flush with distilled water for the first ~hour of garage running, as the passageways in the block were scaled up pretty bad.
Cold oil pressure was around 50-60, hot oil pressure was 15-20. Very happy to hear it run. Also happy to see it shifts and the brakes hold
Need to adjust the shifter linkage, seems a little off. There's very little movement required to shift between gears; I suspect the console shifter is pretty worn out.
