Casting ID help needed 302 crank??

[Bowtiefan]

Good afternoon, my litle brother just traded for a Chevy S10 truck which we will be building for bracket/street racing. This truck came with a freshly machined block,stock rods,12:5:1 pistons and a crank. The crank appears to be a 302 (which is what we were told it was) but my brother really wants to have someone run the numbers on the crank to be 100% positive. The block is supposed to be a 350 block.....but my brother says it looks more like a 327.

We'd both greatly appreciate someone checking these numbers for us:

crank: 3735236 226

block:
3903352

THANKS for any and all help!
