Looking at a 1966 427/425 - The rear end is a not original. The seller is telling us It is a 1966 3.55:1 posi 4speed 327v8 rear end. Stamp reads AN4166. Is this a major concern, being in a Big Block car? We thought the 4.11:1 gearing was preferred for the Big Block, the 3.36:1 ratio was less responsive, but not sure what the seller's information is reflecting. Can't find anything in the Black Book, but seller called it a 327 rear end.
Need your guys expertise - will is this be a big problem in the future? Or is this not a major concern?
Thanks so much for your help in advance!
