I have been running 904s for years behind my mid 500 hp range small blocks doing a 2nd gear only burnout, only two failures in 40 years mainly due to my own fault ( mis aligned shifter lever ) my friends keep trying to talk me into a power glide especially now that most racing around me is 1/8 mile but it would be expensive : driveshaft, shifter, bell housing , converter etc. so the 904 stays
