I don’t think that was the point …. We all know it’s different in a LOT of ways.

If it was a not a small block, not a big block, what do you call it? Besides a HEMI block. A 3rd classification of blocks?
I’m just curious of what your thinking and where you stand on that block size/category.

The Gen lll is it's own series alone from big and small blocks. The A and LA will share some parts, same with the B and RB, even the Hemi will share some parts with a B or RB. Other than the bell housing bolt pattern I don't know of any parts the Gen lll share with a small block. :thumbsup:

If we're going to say the bell housing bolt pattern defines what family the engine is, are all Chevy's big or small blocks?
