I will make it super simple for you....if someone wants to run a 4 speed for the fun factor, great, I have a couple 4 speed cars and they are fun but I don't race them or even have them in very rowdy street strip cars but some do......in regards to the 904 they are a phenomenal transmission and are way faster than a 727 and safer and I dare say that 90 plus percent of the stock eliminator guys that have to technically run a 727 case have 904 guts on the inside as they are obviously lighter which simply equates to a faster overall package. The argument of it can't live over a certain power level is a moot point as every part of these cars can say the same thing and as power increases things need to be modified appropriately.
