the biggest thing when doing is a 904 is to make sure the guy building it knows what they are doing. after that i would say some kind of shift kit.. store bought or builder built. and then the use of quality parts. a 904 will easily hold up to what you have planned for it.. hell the one in my car had the ever living crap beat out of it from 2005 till 2012 when i pulled the car apart. my buddy just put it into his 11.50 cuda the other day.. still working great..:)
-I'd like to retain the stock column shifter and stock pattern...any drawbacks to this? I know most folks reverse the pattern...
