About the only casting number books I know of are the Holander parts interchange book or Chevrolet by the numbers, but in any event most chevy casting numbers you can find on line by part description and part number, Google search them ) those ram horns will fit any 265 thru 400 cubic inch small block, I have a set on my 400, and the only reason as I have no room for anything else in a 37 ford... give me a little while and I will look up the specifics in the chevrolet by the numbers...
3932469 69-70 327 & 350 LH Passenger 235, 250, 255 & 300 HP 2.0" Outlet
3905364 69-72 307, 350 & 400 RH Truck

Can`t find a listing for 3805364, sure it`s not 3905364 69-72 307, 350 & 400 RH Truck

Date codes are LH- Dec 1,70 ..... RH- Aug 2,73

You can casting numbers and date code info on the Tri-five forums and or Nasty z/28 forums...
