How about a good Drag race 904 build discussion

The rollers in my 904 fell out... the drum never exploded and the car drove fine for a while.

You are applying a known issue for a 727 which can be devastating, to a 904. They do not have the same risks.

Your explanation and some of the fixes are close enough regarding failure and consequences related to a 727 only.

904 is smaller and more efficient.
