I believe that you will be looking for a long time for that 426 max wedge or street wedge block. They only had 413 Max Wedges in 1962, and you could probably get a 413 , ( low-po ), street wedge out of an Imperial. Allthe 62 cars had 413 and the 63 body style had the 426 max wedge.Looking for a 1962 426 wedge block. can be a max wedge or a street wedge.
