360 Intake on a 318 - What To Expect?

I think the best idea would be to score a Performer 318 off the web of ebay or a local swap. The intakes are ok. The bigger problem to me is the port mismatch which in this case is the worst you can get in terms of performance. But a 318 intake should be easy and cheap to locate. I''ve got one but it would be cheaper to find one closer than 3K miles...lol.
