cross flow vs. up and down-aluminum radiators

just ordered mine up from FBO. Thanks for this post. i was on the fence about the radiator issue. Aluminum vs Copper. It was cheaper for me to get a new aluminum one from Don than to get another core added to my original rad. The ones from US Radiator are nice but they want almost $500 :sad: I'll be happy with the FBO unit. Don has done me right with everything else I've ordered and he has great pricing. My 2cents
