I have 2000 silverado with a whipple. My buddy has a 2000 lightning and he he swapped intercoolers and he still has his stock intercooler from his lightning. I was wondering will the stock intercooler from a lightning fit the whipple on my silverado?

 

Did he swap the heat exchanger, or did he swap the whole intercooler to the better 01 and up lightning intercooler? If you want to try to put the whole thing on, then don't even think about it. It will in no way work, and the ones from 99-00 lightnings will leak anyway. There may be some parts off it that you could use though if you wanted to fab up your own intercooler, but just a select few parts.
