360 torque converter question

Hi guys
I'm new to this site so if I don't follow proceedure correct me.
I have a built 1978 360 truck engine that is assembeled and ready to go in my 74 duster. I'm removing a 318 that has a 727 transmission in it. The 318 and trans are 1976 out of a camper.The Question is. Can I resuse my 318 torque converter? I purchased a 360 flexplate but from what I read the 360 uses an external balanced torque converter. I've read in a couple of magazines where you can use a 360 converter with a 318 if you knock off the balance weigh but can't find anything about using the 318 converter with a 360 engine.
Any information would be appreciated.

Thanks
