355

Ok now I'm really confused I thought they made a 355 ???

Nope, a 355 SBC is just a .030 over on a 350 SBC, it is probably just a .040 overbore on a 350 making it a 356.88 or 357.

I guess I need to find the #s on the block.

The block numbers won't tell you if it has been bored or stroked, only what it started out as.

Engines are typically always called what their final cubic inches are, you can buy a 355 or a stroker 383 already built but they both will typically use the same block, plus when you do aftermarket stuff you buy a bare block and then bore and stroke it to your needs.
