Hi

Two questions..

1) Can I rest the engine on the ground with the heat exchangers attached? Without any damage?

2) I am trying to figure out these wires - the two at the bottom of pic. One is a single wire and the other is a set. I assume one is for inside light? Whats the second set for?

Yes & yes

I like to rest it on a harbor freight furniture dolly. Makes it easy to move around.

I believe the longer solo wire (lower left in picture) is for the parking brake indicator light. The next shorter multi-wire set (coming from same grommet point) with two female spades would be interior light.

And i completley agree with the dolly for engine storage/portability. Installed heat exhangers would be fine. I would put a thick piece of plywood across the dolly.

You can store the engine that way, but I prefer to have a couple of blocks under the case so that the exhaust is just off the floor (or shelf).

What area do those wires come from? It looks like the box in the upper right is the "Dreaded Seatbelt Interlock Relay", with the "door open" buzzer next to it. Those would be from the cabin, in that case.

What colors are the wires? We can match the colors to the wiring diagrams and figure them out better that way. For instance, I believe that the interior light gets a black wire, a brown wire and a brown/white (brown with a white tracer stripe) wire.

When you say "with heat exchangers attached" do you mean with transmission attached and the end of the HEs attached to the muffler hanger? If the trans is not attached I'm not sure I would rest the engine on the HEs.

I’d try to support the main engine weight under the crankcase and just use the heat exchangers to help balance it. The dolly is definitely a good idea.

If you are leaving the trans and exhaust on the car, the heat exchangers won’t be exposed to any twisting force on the exhaust studs and the engine won’t need any additional support. If it’s just the engine and the heat exchangers, some engine support couldn’t hurt.

The 1000# rated furniture dolly from Home Depot. $16.37.

I can tell you (from experience) the hf wood dolly's are stronger than the metal ones.

I personally wouldn’t use the exchangers to support the weight of the engine.

We have about 30 engines sitting on pallets, granted, most are 6's but there are a couple 4's. The type 4 engine weighs 325lbs fully dressed with trans and exhaust. the 6's weigh between 400-550 without trans. We've never had any issues.
