Dodger, Sorry, I don't have books for 64, but maybe someone on the list either has a 64 Parts Book or 64 Darrell David book? One of the web sites said that P/N may be from 63 and 64, but I don't believe 63. The 63 factory Parts Book does not list 2406 648. The 63 Darrell Davis books have factory bulletins that specify the Max Wedge part numbers. I have the 63 versions only. The factory bulletin lists for pistons: 2421 336, 337, 340, 341 - Piston, 413, 4.18 bore 2448 700, 701, 703, 704 - Piston, 426, 4.25 bore - Jim Jim Altemose, Long Island, NY '63 Polara 500 (Max Wedge) '63 Polara 500 (383) '65 Belvedere I (Street Wedge) '71 Bronco On Thu, Nov 3, 2011 at 2:24 PM, Gary H. <62to65mopar@xxxxxxxxxxx> wrote: > Not sure... > > In the 62-65 mail archive I found this: > >>My car has a '63 426 Max Wedge with the low compression ratio.
