So you want a stock 440 then
I beat up a "Fast" 69 stang with a roller cam 351 using a smog 400 , [1 cylinder only had 17 psi compression !!] in a 69 Dart !! while I didn't win , I also didn't lose , we tied 3 races in a row but if I had had all 8 cylinders he would have been toast !!
So I assume this will be a street car , so you want a long flat powerband with a lot of torque , I would recommend a 512 ci stroker build with a powrband 2500 - 6500 ish this way you can drive it anywhere & still kick butt
