Weighed my Duster!

The 727 is pretty heavy compared to a 904 and a good bit of it is rotating weight. I picked up 2.5 tenths going from 727 to 904, I also changed from a steel shaft to aluminum and went low first gear set and bump the flash up about 300 rpm. Average is about a tenth for the tradition change 727 to 904.

I considered going with a 904 but for a minute I was sure the next motor after the last small block was gonna be a big block so I went ahead with the 727 with plans to put my trans guts in a bb case. I'm not so sure that would workout as I'm not sure where the engine would have set exactly. I was trying to be a forward thinker anyways lol. It may get a 904 or a glide some day.
