Robb,
As you will find on this forum... Its a cruel world out there...
There is no such thing as a small block (SB)... the opposite of big block (BB) is little block (LB)...
Just a suggestion or 2... 1)Go to the search engine and type in "little block forum" or "LB forum" (same results either way)... or 2) ask Cranky aka racer x 99 (still same results)... LOL
