motor mount question

[Tom keedle]

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....
