I hear ya Dr. EVIL on the bad luck or no luck at all thing if you were to install the V2. Just tell your pocket book it needed it anyways, it will understand it. Or, good idea getting the stock location.
As for the this whole V4 vs. stock row thing: it might be hard to believe, but CAS is not only going to rule in the buick world, but put a hurting on the import turbo world also. We truely got luckly to have it in our market first. So, do not doubt your buy, soon thousands will know about extruded tube and fin.
By the way, your movie better be as good as this thread is this summer. (Pinky slowly moves towards lip)
My roomate bought a V4 from ramchargers. He picked up 4 tenths, and he loves it! Its a great lookin piece and the install is easy. I'm runnin a Cotton FMIC and get 190 temps with the ac on in traffic. All I did was just have the radiator done.
