Question on 409 motor mounts

[Rondecurtins]

I just now realized that small block motor mounts may not be the same as the mounts for the 409 engine. If they are different, do the 409 mounts cause the engine sit higher or lower? How about the transmission mount. Is there a difference there?

higher

That's what I thought. Do you have a idea how much higher?

The Chevy parts book shows 3990914 as fitting 58-64 (283, 327, 348)
part no. 3990916 as fitting 61-64 (409) Possibly a little heavy built.

here is a discussion of the 409 motor mounts from a few years ago on this forum

Motor Mounts 409 | 1958-1965 Full size Chevrolet

Need to replace motor mounts on my 62 409 driver car. Been trying to do internet research including this site and still can't figure out what brand I should get. Don't want to have to do the job again but also don't want to use solid racing type mounts.

The engine mounts Paul mentioned are correct. Rock Auto $9.98 ea
Just a note about Anchor mounts that I ran into. The 2285 engine mounts are correct for the 409 and "made in USA".
The 2378 trans mount can be made in the USA or Korea. The USA version has 7/16 threads for mounting to the cross member like the OE mount. The Korean made mount has 3/8 threaded holes. This according to Anchor this was a mistake on the manufacturers part. However I just re-drilled & tapped the Korean mount to 7/14. Ordered all 3 from the Rock.

Thanks to all of you for your replies. Sometime ago I ordered the engine and transmission mounts from Summit. The catalog did not specify a difference between Small block and 409 block. I assumed that they were the same. My mistake.
