How to build small block chev engine mounts

Since I have no real work, due to this economic mess, I have taken a bit of time to post something that may benefit all of you who were wondering how to mount a small block chev engine into your model A, (or any hotrod, for that matter). The following attachment shows the mounts and how I build them.

 

First of course, you will want to build the portion of the mount that bolts to the side of the engine---

 

Then you will need to build the plates that attach to the frame---

 

And this is how it goes together---

 

Doesent that style mount act as a wedge..putting pressure spreading the rails??

 

Once it's bolted together it's pulling as much as it's pushing! As always, nice work Brian. Clear, concise, and color-coded!

 

And here is a bit more information---

 

x2 ??

 

No boys, it doesn't act as a wedge. The engine block and the side mounts that bolt to it act as a "composite beam" from an engineering standpoint, and the force/weight is directed straight down. There is a slight lever arm effect on both frame rails, but they are lots resistant to torsional "twisting" because they are a rectangular cross section. This type of mount will adequately support any small block Chev engine ever made, without failing or damaging the frame rails. The type of mount with a tubular member that passes under the oilpan works very good too, but it is practically impossible to use with a Vega cross throw steering.---Brian

 

Another plus for this type of engine mount, is that nothing on the mount extends out onto the top of the framerail. This means that there is no obstruction if you should want to run front fenders on your car.

 

Here are some shots of the engine mounts on my roadster pickup when I was building it 5 years ago.

 

Dude - that's BADASS!!!

Very nice drawings...........Thanks

 

Sweet!!! Man, that's clean, looks like you subscribe to the KISS principle.

 

Brian, what are those big plates sticking out the top side of the frame rails for?

 

I use that style mounts no problem! Sweet man,Great stuff keep it coming !!!

 

Pasadenahotrod---Do ya mean my upper shock mounts?

 

Nice design and great drawings! Thanks for posting this.

 

I think he's talking about the running board areas??

 

Beautiful illustrations and blueprints! I'm saving these for future use. Thanks for sharing and good luck with future employment. An employer would be blessed with your skills.

 

If thats the case---My splash aprons are fiberglass. They stick out a fair distance from the frame on each side. Those plates are on there to give additional support and rigidity to the splash aprons.

 

And now, on to the rear tranny mounts (If you are using an automatic tranny).

 

And a bit more---

 

Now this is why I joined up.
EXCELLENT illustrations !!!
What program did you use ?
THANK YOU !!!

 

And the crossmember itself---

Nice work Brian, glad to see some nice prints.

 

Got it. I was think that might be the purpose.

 

And one last drawing, with a bit of critical information. Remember--this is what worked for me---and worked extremely well. You may have done something different, and been succesfull with what you did. I don't want to hear why this won't work, because I built my car 5 years ago, and have been driving it ever since. There is a thousand different ways to make motor mounts, but this is what worked for me.
