Primed and started the new 400 motor today.
Added a half quart of Penzoil SAE 30 to the oil filter. Another 4 qts to the engine, with a 16 Oz bottle of Lucas oil TB-zinc break in oil.
Took a few seconds of priming and we had 50 psi oil pressure. After about 2 minutes (maybe less) we had oil flow through all push-rods. The priming tool I purchased from Performance Olds worked like a charm. We placed cardboard into the heads to prevent oil from leaking onto the engine. Again, worked like a charm.
We did not rotate the crank. Buttoned it up, Made sure we had the #1 cylinder at TDC (compression stroke-timing mark at 0), then placed the timing mark at 10 degrees. Made sure the distributor was pointing at the #1 cylinder in the cap, and that the wires were properly routed to the correct cylinders per the firing order.
Added some fuel to the carburetor bowls, and made sure the throttle body was squirting fuel.
Turned the key and instant start, and I mean instant. Had some fuel leaking, so shut it down, tightened the connections and started it back up. After about 15 minutes at 1800 RPM the car was running hot (200) so we shut it down again. It seemed the NOS clutch fan was was not operating correctly as it was spinning freely despite the hot motor (should be stiff at that point). It was not pushing much air.
Removed the clutch fan, installed a regular 7-blade fan, and restarted it. Ran it again for another 15-20 minutes at 1800 RPM, temperature remained at 180 the whole time. The amount of airflow from the regular fan blade was night and day as compared to the clutch fan (defective). Oil pressure the whole time was 42 psi.
It's been a long process but feels good to get to this milestone. Still need some tweaking, there may be a vacuum leak, although we were unable to locate any. Going to remove the carb to look at the gasket to make sure it covers the entire perimeter as it should. I hope this is it as vacuum leaks can be a PIA to find.
