Motor mounts

[chris ok]

Is it the frame mounts that move the engine or the engine mounts?
I see moroso offers mounts but look like matching pairs. Same as energy suspension.

Frame mounts relocate engine. Going from memory about 3/4 or 1 inch.
It's not much but enough to make a difference in fitting headers.
'67-'68 are different from '69, so the motor mounts are different for '69 also.
Don't know why they changed but the width is different.

Also 302 engine frame mount is shorter also...
So there is that...

My '67 car was a 327 originally. When I built it as a 302, no problems with fitting. Later I decided to convert to a big block, so I went to Chevrolet and purchased new 396 frame mounts. I ordered headers from Jack Davis and when I tried to install them, they would not clear the crossmember. Jack said the headers were designed to use small block frame mounts "because everybody does that to move the engine back". So the small block mounts wen back into the car.

There is a difference.

My '67 was originally a 350 car, when I got it, previous owner had a big block in it, headers hit steering shaft...
Went to Chevy and bought big block mounts and fixed that...

They lowered the 302 for carb/air cleaner fit.
Other than that, nothing dimensionally different, small block is small block.
(probably useless trivia)
