Before dismantling anything, put the motor on TDC  (P) — with cam lobes pointed out and distributor rotor pointing to cylinder #1. This makes life easier if you’re going to remove the head or even if you plan to remove the timing chain.  The rotor moves in a clockwise direction, in this order: 1, 3, 4, 2.  Depending on how the oil pump was indexed when installed, your rotor may point in a different direction than my car when it is aimed at #1 .  The key is to have the cylinder #1 cam lobes pointed out and the distributor rotor on cylinder #1, when the engine is on TDC (P).   Check the your plug wires as they fit into the distributor cap, beginning with #1, and proceeding around the clock to 3, 4 and 2.  On my car, the rotor is aimed down on #1 (6 o’clock).
Take pictures of wiring before removing any to aid reinstall process
Take off the good lifting bracket and put on the old, scratched bracket
Remove hood
Remove front sway bar
Drop one side of steering center link
Disconnect and remove battery
Drain sump
Drain radiator
Remove radiator thermostat sensor from radiator (I have an electric fan)
Detach wires from radiator fan (one slip-on and on ground to same post as battery ground)
Remove radiator

Passenger side of engine
Remove spark plug wires and distributor cap
Disconnect oil temp and oil pressure wires
Disconnect fuel line and linkage to carbs (when reassembling, don’t forget to attach the carb to block ground)
Remove  carbs (easier to get motor in and out – my carbs are attached to long aluminum mounts)
Remember to reinstall the ground strap from rear carb to block.
Disconnect wires from coil to distributor  (note which goes where – a photo helps those of us with aging brains)
Detach oil vapor line from cam cover & remove vapor canister
Detach vacuum line at rear of engine
Disconnect wires from starter, after first noting what goes where
Disconnect bolts that hold motor mount to frame
Remove bolts to tranny, which removes starter (be careful to note which is the starter shoulder bolt and remember which bolts are longer, which have nuts on end)  When reassembling, don’t forget to reattach the block to frame ground.

Driver side of block
Unhook wires to alternator (one main and one slip-on for ammeter warning light)
Remove alternator (not necessary, but makes life easier)
Disconnect bolts that hold motor mount to frame
Remove good engine lifting bracket from cylinder head and replace with old one (to keep the good one from getting scratched)
From under car, remove as much of exhaust system as necessary to disconnect it from the exhaust header.  (My header won’t come off until the engine is lifted slightly off its mounts.  Installation also requires the engine to be lifted slightly. It also helps on my car if I have have an assistant under the car to slide the header tube into the exhaust pipe)
Remove the lock nuts from the exhaust header with 10mm small socket set and end wrench.  Leave header on the studs until the engine is lifted slightly, so there’s room to pull it off. (Custom header)
Put at least 4” of wood block spacers under the two front tires, to lift the car enough so the engine hoist feet will slide under the car
With rear of car on ground, engine should lift right out using a standard portable hoist

Engine install notes
On my block, there is one sensor on  driver’s side near bottom of engine that is for a 2L car’s warning light.  The sensor is there to fill the hole; it gets no wire)
If the oil dipstick housing was removed after the engine was taken out, reinstall it before the engine goes back in
Lightly grease the transmission pilot shaft
If you’ve used a pilot shaft alignment tool to install your clutch and pressure plate, installation of the motor should not be difficult, though it may take some fiddling to slide the clutch onto the pilot shaft
DO NOT FORGET TO DROP THE STEERING CENTER LINK.  If you don’t, the motor won’t go in and you’ll bend the link trying

After the engine is in
Check that oil drain plug and oil filter are tight
Add engine oil
Put assembly lube on the cam lobes
Fill the cylinder head galleries with oil
Install rear cam cover oil seals with light coating of sealant (Ultra Grey is good)
