Motorcycle Repair: Oil Cooler Comparison for 1979 Shovelhead, oil coolers, comparison info

Question
My question is where I can find comparison info on Sifton Oil Coolers vs. Billet Oil Coolers?

Answer
Boy that is a tough one. Not sure if you are going to find that information anywhere. Many of the mags do comparisions on products, but it would be tough to find the right issue.
I would suggest contacting sifton through e-mail and ask them. I am sure they hae done some comparisions and might be able to send you some info.
Sorry I couldnt be more help
