Ifit's only for a short time and you think before you shoot then you could probably still drive it , but if you are going to put it in and beat the snot out of it then , you'll be pulling it back out sooner than you think.
I know on my Dad's 72 duster with the 318 , as soon as I installed headers on it, put in an 8 3/4 with 3.23's and started beating the snot out of it , 17 yr old that just got his license, the 904 didn't last long ... the 7 1/4 took a dump first. Granted I doubt he ever had the fluid changed and the car had about 80k on it when I got my license .
