I had a 360/904 in my drag car (82 Cordoba) It was a decent combo and the trans worked great. I rebuilt the 904 with a TransGo TF-2 kit. That kit made a ton of line pressure so you had to be careful while in reverse so you wouldn't bend the apply lever but I never had a problem with it. As long as you aren't trying to build a 10 second car, I think the 904 will be fine as long as you go through it.
