wrong or upside down motor mounts???
wrong or upside down motor mounts??? I tried a test fit today. I could not get the the engine mounts down all the way. I got them from Napa. I have a p/n somewhere, will post it later. I didn't have anymore time to mess with it, but I thought maybe they were upside down or i got the wrong ones alltogether. Any thoughts or ideas are welcome. Thanks
Your motor plates and mounts are upside down for one..........
Did your car have a big block, or a six cylinder in it originally? The reason I ask, is the pedestals look awfully short.......take a look at the link...these appear to be taller, and will probably solve your problem....it appears that you have big block mounts which are shorter.....notice the difference in height between the big block and small block pedestals.......you want the small block....

Ok plates were upside down, but still didn't fit. It was hitting the oil pain. Put in 1/2" shims, then the bolts would not line up. Knocked out the tube inside the engine stand and bored out the holes. This is how it turned out....

Ok, lets clear some things up,
SBC 350 and BBC 396+ all can use the same motor mounts/ frame mounts
The SBC 307 had the taller frame mount
We ran into a problem like this, I had a BBC previously... The cure was to go with the energy suspension motor mount #3117... I still used the same frame mounts as used on my BBC 468....
Look at your motor mounts and see how it looks like you bent them in to fit, thats wrong.... The back plate on those OEM mounts sometimes do not line up well with the adapter plates.

Those look like SBC 307 frame mounts but should be the SBC 350 BBC mounts the height is throwing me off.... ... Look at the gap on the side between the motor mount and frame stand... Please do not bend it in, get the correct combo or you will have other problems....
Either swap the motor mounts or frame mounts, they both are not made for each other..

I believe this is the exact same issue I am struggling with on my '69 Nova with LQ4 (408). I am using my old Moroso SBC solid engine mounts with the stock frame pedestals. But my Moroso oil pan on the 408 hits the crossmember before I can get the second bolt lined up. I bet the taller pedestal mounts will solve it for me. I only need about ¼" to get the mounts lined up and a little clearance for the oil pan. Does anyone know the difference in height between the two pedestal frame mounts? My pedestals are roughly 2" from crossmember to centerline of the bolt hole.
Here is my passenger side with misalignment - the driver's side mount is lined up but the oil pan touches the crossmember.

Yes the Energy Suspension #3117 should work.....
The 3117 is narrower than the stock oem which should clear your problem and give you clearance with the adapter plate which is not as bulky as the oem's
Also what kind of adapter plate are you using? You might want to use what ever motor mount the adapt plate manufactor suggest

The thinking was that the SBC 350 and BBC frame mounts needed to be narrower do to they moved the block forward.... Actually in some GM cars, the mounts are offset drivers side may be higher than the passenger side, but we don't really want to go into that right now... I know for miy set up I had a BBC 396 and 468..... When I dropped the LS in the OEM motor mounts were too wide and what had happennd was they were bent in to fit by the guy I bought my car from... The Energey Supsenion 3117 motor mounts fit nice abd snug as they should.
So in essence, the 307 would be wider because it places the motor further back, the SBC 350 BBC mounts place the motor a little forward.....
read this:
1968 - 1972: From 1968 to 1972, Chevrolet used two
different frame stands with matching engine isolators. Type
one is the 307 (and some early 1968 327’s), while type two
includes all engines from the later 1968 327’s through to the
454, encompassing all engine sizes in-between. If you have
obtained frame stands from another vehicle, use the
following procedure to identify your mount system: measure
the ears of the engine isolator where the engine mounting
bolt goes, the inside dimension is 2 5/8” for the 307 cid
(Figure 3) and 2 3/8” for the larger sized engine (Figure 4).
Frame stands for the late 327, 350 to 454 are also available
from reproduction suppliers such as OPGI and Yearone,
engine isolators can be of the OEM rubber type from a parts
supplier or polyurethane safety mounts from Energy
Suspension: part #3.1114 (zinc plated) #3.1115 (chrome) for
the 307, part #3.1117 (zinc plated) or #3.1118 (chrome) for
the late 327 to the 454. - Edelbrock

camarosandclassics.com has these frame mounts p/n mt3478 and engine mounts p/n mt3473. Thes are the same ones I have, and they have going together.
All my bolts are still loose, but everything lines up. It is also snug and solid.
What other problems could I have? If it is safe and solid what are things could go wrong? I can only think of the drive line angle.
Thanks for any input
