505 rb build advice needed for 39 dodge

thanks guys! alot of good info.i was looking at flow numbers that came from different sources,nice to see them all from the same place. i now im overkilling the **** out of this but i overkilled the tranny when i built it too and i want the truck to back up the look i was after.looks like ill lean toward a set of cleaned up rpm,s,solid mech cam and hs rockers,and save a few bucks. so who would you recommend i call on the cam?

im working on the body now,had it blasted and just getting all the metal work finished up.its going to be hot rod black in the end.ive pretty much got everything to put it together allready and shooting to have it running by march early june,work out any bugs and then put the 505 in.

the local machinist is a good friend of mine and well go over everything with a fine tooth comb.
