motor mount question

[Lew Silverman]

Greg,

As I remember the frame brackets were different, because of the the way the six sat in the chassis, versus the V-8. I believe the V-8's all used the same frame bracket, Group 0.029.

I had to change out the frame mounts (stands) on my '71 when I went from the 6 banger to a SBC.

The frame mounts are the same as 1st gen Camaro, but I cant recall L6 frame brackets being the same or not, and parts houses are not listing them separately... My 68 had a straight 6 when got it, but we changed that out in 1987 and I cant remember that far back.

usta be the big trick was to use small block frame mounts with a big block (set the engine back a bit) but i cant tell ya as far as the 6 vs 8 frame mounts.
i got a pair of V8 ones if you need 'em....

From memory, the frame brackets are different for 6 cyl., small block, and big block. If I am correct, the small and big block mounts differ in the offset side to side ie the big block mounts move the motor slightly to the right for clearance from the factory. You can bolt the big block into the car on small block frame mounts, but may have issues such as header clearance or oil pan depending on what you have. Companies like Elston headers apparently have a Camaro clip setup as an adjustable jig for whichever set you are using and need to know to properly fit their custom headers to your chassis. There might be info on their web site, but in any case the different frame brackets are readily available from Year One and other reproduction suppliers. Hope this helps....
