My 1942 Ford GPW

is all original and love it, but....
I have built a 49-53 1CM, with 4" stroke crankshaft, stock EAB cam, milled heads to .045 clearance, and 2GC Rochester carb, chevy distributor modified for flathead with AOD transmission. I'm putting this into 39 ford pickup that will be on the road soon I hope. I have dual exhaust with Red's headers.
I'm considering going to a cam something other than stock (wife and daughter love sound of engine with hot cam) and wanted some opinions/feed back from those that are running an automatic transmission with more than a stock cam. I do parades from time to time, very slow, lot of stopping; along with city driving. By the time I finish a parade with the GPW I can hardly walk and looking for something fun, with sound that is the same day after day cranking and driving.
Just asking before I jump off the cliff.
Thanks for all comments.
