AARcuda. first thing I was talking about new stuff and everyone like u cant rebuild trans or having parts laying around.in my case for me to switch to a 904 was a lot of money.the 904 race trans was $2300 plus another $1000 converter.$3300 for .15 NOPE. or 2100 for a race 727 and I had a converter. But I got a race trans for $1800. To me I would rather put a glass bumper on my car for $150 and pick up a tenth and have a worry free 727.But my car should run low low 9s too
