Doing a cam swap on my Savoy and while I have the radiator out I was going to replace the 22" unit with a 26" core. I have read good reviews about the Speed Cooling radiator and there are many people on here that like the Champion radiator. The Champion uses 3 small rows while Speed Cooling claims there 2 large tubes are superior to the small 3 tubes which makes sense to me. I plan on adding a shroud too so that will also be a factor in my final choice. I don't mind some cutting and drilling minor fab work to make it fit as I will have to do some mods to my car to take the 26" rad where the 22" rad was.
