    HI

    I have a 1981 impala wagon and I want to put a 496 tall deck fresh rebuild I have done.
    Anyone knows if the tall deck does fit with the ac and tall valve covers? any pics?
    Im swaping the rear end too. It has the 10 bolt 8.750 with a 2.73 gear and I build a 10 bolt 8.5 with a 4.56.
    I got pics I will upload later.

    thanks

    I think you would be pushing it with a tall block. There is a big block build for an Impala on the forums. It does not have close ups for the heat exchanger assembly, but it would give you some indication.
