that means you got the big block, but posted your question in the small block magnum section of our forum (I was afraid maybe you did have a magnum, in which case the HP numbers weren't unacceptable)
don't freak out if this thread disappears, one of our moderators is bound to move it to our big block section:
Big Block A body Tech

Oh shoot! Sorry about that my bad. Ya it’s defiantly a big block.
