Motor mount issue

[Bill Rose]

As many here may know, I'm building a 69 big block Nova, that was originally a 6 cyl/powerglide car.

I have the repro frame mounts, and basic rubber big block motor mounts. I knew the motor sat low, but I thought it was ok/normal. Now that I have the fan and shroud installed, it doesn't look right. I looked closer at the gap between the oil pan and the frame crossmember, and I can't slide a piece of paper between them. Obviously, the engine is sitting to low. It has the correct oil pan, so the issue is with the engine stands, or the motor mounts. Those are the only parts that determine the height of the engine.

Everything is set up like an L-78 would be. I'm stumped. Not sure what to do. There should be no need for spacers. The original big blocks fit, and this should be no different.

Has anyone dealt with this issue with a Nova or Camaro?

The BB engine's in Nova's like Camaro's is offset to the passenger side.

Can you put a pic or post the frame stand numbers and the engine mount numbers?
69 BB's used a unique non interlocking HD motor mount from the assembly line and all other's are just replacements, there have been issues with different brands of replacement mounts.

Bill, 1967-68 Camaro and 1968 Nova have the same engine frame mounts. 1969 Camaro and 1969-70 Nova are the same. I assume you have the correct ones for a '69 Nova.

If so, double check the motor mounts because as stated above, there are different ones for each application and sometimes the wrong ones get sent. BBC motor mounts are specific to the frame mounts.

Hope that helps, Kurt

Thanks guys. Maybe this helps describe my problem. The frame mounts are repro's from Ground-Up, the same ones that all the vendors sell for BB Nova's. The motor mounts are also from GU. I have no idea if they are right.n Ground-Up lists all the motor mounts the same, for Chevelles, Nova's Camaro's etc...

Here are 3 pics of the motor mounts. The 1st is before the engine was installed, with the motor mounts bolted to the frame mounts.

The other 2 are the best best pics I could get of the mounts today.







These are the motor mounts GU is selling for BB 69 Nova's.

Your engine frame mounts should look like these from the side.

Engine Frame Mounts

Kurt, those are the frame mounts that I have in the Nova. I'm wondering if the Motor mounts are wrong.

measure the height of the motor mounts from the engine side to the hole....

we can compare these to the correct GM interlocking motor mounts.

I am no Chevy guru but are you sure the rubber mounts you have aren't for a small block? The 350 in my old Z11 had one wrong motor mount and it turned out that it was from a big block. The result was that one side of the motor was way too high. They were different thicknesses but the same bolt pattern.

[Bill Rose]

Steve....GU is listing all the big block cars with the same motor mounts. They are for a big block, but I don't think they are for Novas. Chevelles.....maybe?

Here is a shot of the mounts with a measurement. Looks real close to 2&1/4".

Here is a link to David Pozzi's site. It was stated earlier that Camaro and Nova share the same mounts and brackets. It gives a few measurements that might help you out.
