I will be storing a big block engine and transmission in my garage for a while, and I want to build a support dolly on wheels for it. I don't have the engine and trans yet to take measurements, and I would like to have the dolly built before I get it. I don't need it to bolt in, just to not wobble and fall off the dolly while I roll it around. Other than the wheels, I am hoping to build it with scrap lumber and some perforated steel angles that I have laying around in my garage.

I'm thinking about something that has three support points to correspond to the transmission cross member and the motor mounts. Does anyone have the dimensions of these three points? I need the following dimensions:

1. The horizontal spacing of the motor mounts.
2. The distance between the motor mounts and the transmission cross member.
3. The vertical offset between the transmission cross member and the motor mounts.

These dimensions can be approximate, and I can shim it up, but I would just like to put something strong below these points, as this is where the load will be taken.

Alternatively, I am open to suggestions to doing something else. I thought about going to Harbor Freight and buying three of those dollies that accept a tire, that you use to be able to roll your entire car around in the garage. One each under where the motor mounts attach and one under the transmission cross member support point. I would like to spend as little as possible, so since I know I would end up buying four of these to use under a car in the future, this is not as desirable as my home-built dolly.

Any other ideas?
