Pick up a 318 or continue my search for a 360

Hello,

My current project has a tore down non-working (Was torn down 17-18 years ago and never put back together) 318. I was looking for a 360 to put in its place from recommendations here. However, I have found a supposed working 318 with a 904 transmission and converter for $350. The owner knows little about it other that it was slightly modified and was running when pulled from the vehicle. He was only able to say that it came from a performance shop and was removed in favor of a crate engine. So in short the history of the engine is unknown.
Should I keep looking for a 360 to build or pick up this 318 which in theory I can drop in the car and be one step closer to having the car run. $350.00 is not a lot, but time and effort right now seems to be a commodity.

Thanks
