trade small block for 6 cyl

[6772KEVIN]

I have two small block chevy engines, both are complete and running. One is a 350 and the other I was told was a 350 but my be a 305, im not sure. Like I said they are both complete and running motors. I also have a 3spd trans to go with either one. I would like to trade for a good running 250 or 292 6cyl. Let me know what you have. I can get pics of both engines if needed. both are in running and driving trucks.
