I just pulled my motor out of my '70 C-10 thinking it was the stock 350 like the guy said that i bought it from to change my flywheel. Ran the numbers and its a 68 327 (not mad actually rather have a 327, be different)

So i have it out and i dont want to just put it back in and not beable to tell the difference. Dont got a whole lot of money and just want to bump up the horse a little.

Any ideas?
