68 Camaro big block or not?

[bobwags]

How can I tell if a 68 Camaro was originally big block car?  The car I am looking at has a 350 in it that is not original but the owner says he thinks it originally came with a 396.  If it was originally a 396, does that mean it also was an SS?
Thanks

Big block will have a different heater core cover, engine mounts, fan shroud, etc. The only true way to know is with paperwork for a '68. If it indeed had a 396 originally then it had to be an SS.

also check HP rate on the title.

What transmission and rear axle does it have?
Other distinguishing features of big block were the hi rise hood with stack style ornaments and satin blacked out rear tailight panel [some exceptions i.e black body paint]
