Can someone decode a block for me?

[hugger6933]

I got a 70 swb truck in a couple of weeks ago and was told that it has a 327 in it. I offered in correction 307? the truck has a pretty small spid no brakes or power steering, no air noof everything. Imade the assumption that it would be the 307. They assured me it was a 327. I bought ot from the local school district and supposedly the man that drove it was the only one allowed to do so and he was in charde. When the 327's were being phased out in the gererals inventory they purchased one for this truck. ans with just a few years left they installed it for him. He drove it till the day he retired and then they parked it till I bought it. That is the story sorry to ramble as I often do but the numbers are VOT23YH. Any help in decoding would help me figure out witch cam may be best for me and what not. Jim
