anyone hear of a h-p big block sawtooth 318?

Poly 318, NO doubt!
Heavy early SMALL BLOCK.
Never was a Big Block 318. Some Chebbie guys think so!

I agree, sounds like a Poly.
Since the 318 Poly was essentially the same block as a 392 Hemi, I would call it a big block too. It is certainly bigger than a LA 318. Quite possibly I have just proved that , I don't have to be a Chebbie guy to be an idiot:sad5:
Someone help us out here?
