727 or 904

I didnt vote because i like 3 of the options. Id love to have a 4 speed, i built a 904 for my car. 727 is a very stout piece, I guess thats why they came in all my trucks. My 727 in my ramcharger is as built as it needs to be, bolt in sprag and a 4 clutch front drum. But, I dont spin it to 6600 rpm either. 6600 x 2.45= 16170 rpm
