HELP(engine)

[canadian_muscle]

I've got a 76'firebird with a 350 big block american, now here's
the problem i can't find any info on my engine. the block is roughly an inch bigger than a 350 but about 3/4 of an inch smaller than a 400 small block. but becuase it is an american engine and i'm in canada it's considered a rare motor and only a few people have heard of it. IF ANYONE CAN HELP, IT WOULD BE GREATLY APPRECIATED.

Here's a link to a site with a ton of info, do some digging for yourself and it should give you what you want.
