I think it may have come about when Chevy came along with the "rat motor 402"(396) and called it a 400 then had the "mouse motor 400" so it was called big block 400 and small block 400. Just an opinion.
That car looks great with those wheels. I've been burning CL up looking for a "deal" and only come up with rusted over priced stuff close to me. I'd be willing to drive 200mi for the "right A-body".
