Can anyone confirm or expand on the existence of dimples on motor mounts used on SS and Z28 cars?

 

i'm pretty sure there is 2

 

I have never seen them listed anyhwere, differently than any others, and I have seen lots of little things that normally wouldn't make a functional difference on a car, so I say your myth is DOUBTFUL and most likely BUSTED.

sounds like someone was just fishing to start a strange rumor

 

I think someone fed you some confusing info somewhere. It's not the rubber "motor mount" that has the distinguishing dimples, it's the Engine Frame Bracket that bolts to the subframe that does. Yes it's true, they are different for the SS350 and Z/28, at least for 1969 models anyway. They are a lower profile to give a little more hood clearance and look like this:

I have looked for info on this recently and have come up with NO INFO either way. As if nobody has ever seen or heard of it. I Certainly wouldnt use it to distinguish a car as an SS or a Z28. There are alot of other ways to determine the pedigree of a car

 

I finnaly got this reply about this subject ...69 z/28 and 350 cars used the dimple mounts, the 307 and 327 used taller ones. The bb were shorter and there was a short and a tall. in 67 68 no dimple mounts were used. I am still waiting to hear from a few camaro experts on this hopefully they will chime in

 

What happened? Did my response not show up on your screen? Look up a couple of posts!

 

I read what you said However Ive never heard of it b4 so I asked some well know camaro guys for some answers is all when i hear from them I'LL post it too. I am not in saying it isnt so just verifying Never do i take one opinon as the truth is all

Q: [23-Dec-1998] Correction: Do all V8 1967-69 Camaros use the same engine mounts and engine mount (frame) brackets?
A: No. Let's start with small-block Chevy (SBC) V8s. All '67-'68 SBC and '69 307ci and 327ci engines used the same engine mount bracket (approximately 2-1/2 inches wide). The 1969 302ci and 350ci engines used a shorter (~3/8 inch) and narrower (~1/4 inch) bracket. (The engine mount relationships for these brackets are best described in the table below rather than in text.) Note that, unfortunately, 1967-68 engine mounts will assemble to the 1969 302/350 engine mount bracket, but this is an incorrect assembly that results in driveline vibration and clutch chatter because the engine sits too low and can move on the bracket.
Looking at big block Chevy (BBC) engines, in order to gain engine compartment clearance the engine was offset 1 inch to the right (towards the passenger side) by means of asymmetric brackets. 1967-68 BBC engine mount brackets are 2-1/2 inches wide (but not the same as SBC) and use the same corresponding engine mount as 302ci and 350ci SBC. For '69, BBC engine mount brackets were redesigned to use the new thicker, narrower, engine mount also used by 302ci and 350ci. BBC bracket pairs are easily spotted because the left bracket is noticeably taller than the right in order to achieve the engine offset.
To summarize the engine mounting differences, from the Dec '71, GM of Canada Master Parts Catalogue 721, we see the following relationships:
