Good progress last 2 days, engine about ready to be mated with bell housing and transmission, hope to have it back in the car next week. Thanks to all the support out there!
And a pedal cluster question. Mine had some slop, took it apart and the shaft is worn where the frame support bracket hits the shaft, Trying to figure out the purpose in life of the large spring and washers between the bracket and the clutch pedal. Does it do more than provide the force of th e"D" shaped shaft insert into the frame? Since I can't find a new shaft, thinking of welding a wide collar on the frame side of the support bracket which them provide far more support across the shaft than the bracket did in point contact and make up any difference in width with 7/8" diameter shims Comments or even better, a source for that shaft?

The last picture should have everybody responding.
The breather pipe is missing.

Tim, I don't understand your comment, the breather pipe is simply not installed yet. Perhaps you're thinking it should be attached to the rear tappet cover but that's not the case with this motor.

Actually, on this engine, the breather comes from the fitting on the right rear of the block, through a copper tube to a PVC valve into the intake manifold, go figure!

Engine stand worked out great. Next challenge is to finish assy, bell housing, flywheel, pressure plate clutch, throwout and transmission while dangling from the engine hoist!

Hi John,
Looks great. I forget what year your car/motor is, but regardless, I definitely would not put the crankcase breather on until after the engine is sitting squarely in the engine bay. It is a fairly tight fit as it is (with bell housing and tranny attached) and the breather tube is just 'one more thing' to catch and snag on everything, possibly getting damaged in the process. (be extra careful with the accelerator linkage when lowering it in as it is really easy to damage) Re 'inserting' the transmission, Napa sells a universal shaft adapter to center the clutch disc. It is 'cheap like chips' and really helps unless you happen to have a spare Packard splined shaft to use. It has different bushings to match up with your pilot bearing hole. I found leaving the pressure plate bolts loose so the plate JUST held the disc in place and centering it by eye, then fine tuning it with the adapter shaft and the tranny slid right in. You say the breather leads to a PCV valve? I haven't seen that setup before. Mine just bolts on where that large nut is just aft of the rear tappet cover and has an anchoring bracket that shares a bolt with the clutch trash cover and exhausts straight down, towards the ground. I can see why Tim thought it was missing, but it is simply, as Dave says, not yet installed, nor should it be. I tried to find a decent picture of mine but could only come up with this one showing it in place. It looks like that nut on your motor is set up for a flare or compression fitting, John. Do you think it is a factory setup? Chris

The breather is a short run, next to the block up to the manifold. Manifolds aren't going on till after I have this all in the car. Front clip is completely off, ie: both inner and outer fenders and of course the grill.
IMO, I don't believe this was a factory install as whoever drilled the manifold did a pretty crappy job. I am redoing the entire firewall as well, so everything is off of it, including the throttle linkage which I just finished restoring. I have the tools that align that, thanks.
