On my '69,I "caught wind" of possibly needing taller/different engine frame mounts due to switching from a 350sbc to Gen.VI 454bbc with Hooker Super Comp.headers and Moroso oil pan.I've looked all over and all I can find is the same frame mounts fit small or big block.Any input would be helpful,as I'd hate to have the bb in the hole just to find out it won't set in.

IIRC, frame mounts are the same for a 350 or a big block. A factory 307 car uses different frame mounts, and a big block can be successfully installed using 307 mounts on the engine side. (I've done two) There are now interlocking 307 engine side mounts made.
