302 Motor Mount Dimensions?

I would like to know the distance between the right and left side mounts on a 302. I am building a cart to pick up an engine and would like to do it before I have the engine in hand.

I sure would like to see this engine stand assembled with an engine mounted on it. I think that the 14.75 inch dimension corresponds to the motor mount mounting holes in the block but it's hard to tell without seeing an isometric drawing of this stand. This is the kind of stand I am looking to build though.

That picture wouldn't be for mounting directly to the block as the mounts on the block are offset like 1". The rubber engine mounts are what make it straight across.

Just need to find someone that can measure one of those universal engine mount crossmembers that everyone sells.

Thanks Ross, photos of the finished product answer a lot of questions. The drawing only showed a "plan view", top down which did not depict the actual height of the stanchions.
Nathan, I believe that the drawing does in fact depict the plates that mount directly to the block as the "biscuit" style shock isolators are located under the plate. This design does not use the stock SBF motor mounts. If you use the dimensions on this drawing to fabricate your stand then you wouldn't need the universal dimensions.

I believe that my question has been answered...the design will change to copy this drawing, only on mine I won't need the biscuits as I won't be running an engine on the stand. Thanks again Ross.

There are a lot of stands on the 'net that use sliding posts on the crossbar, so they can be used for multiple engines. If you aren't running the engine that would seem to make sense.

Charlie, Tonyb55 built a stand that bolts to the 302 block without any mounts. Maybe he can can measure his for you. He's a little under the weather this weekend tho, he had some chest pains the Docs are checking out.

Since my engine is sitting in my living room at the moment. It's 13" approx between the left and right mounting bosses on the block. This shows that they are offset 1" from each other.

Well I think that using all the info provided, I have come to an answer to my original question. The left and right motor mount bosses are offset (front to rear) by the width of one connecting rod, using Nathan's photo we see that this is about 1 inch. It is also noted that the motor mount itself is offset...when mounted on the right side of the engine the isolator block shifts forward, vice versa on the left side. Ford designed these mounts very well...one part number fits both sides even though the position on the engine block is different. I have included a pic of the two mounts side by side, the green lines show how the mounts are offset when the mounting tabs are in line.
My initial question however related to the distance between the bolts that mount the engine to the chassis. If the bosses in the block are 13 inches apart then the distance between the chassis mounting bolts is 13 + 2 + 2 or 17 inches. In the pic of the single mount, there are two lines shown...the distance between them is 2 inches, that's where the 2's came from. Thanks to all for your inputs!

For those interested, Paul Horton Welder's Series makes a really nice set of motor mount brackets for the SBF, check them out at Ford Motor Mounts – Rubber Insulated | Welder Series Inc. only $47. The video on the URL is very helpful.

The motor mounts in the photos above I bought at O'Reilly...they are made by Anchor, part number 2257. Here's the best part, they are made in the USA and only cost $10 each.

skuzzel_butt is starting off with a positive reputation.
Here's an version of a stand I built real simple, no need to worry about the width as they are separate pieces.

I have an update on the motor mounts from Horton Welders Series...the tabs are reversed from those on all the OEM mounts that I have seen. Horton sells mounts (rubber isolators) that have the proper mounting hole alignment but I have an issue with availability down the road should I need to replace a mount. I am going to cut the mount and reverse the tab so that it matches the motor mounts that are readily available at parts stores locally. Here is a pic of the mount...
