A Ford guy here...

yah I’m not sure it’s poorly done. But I’ve been looking at the QA1 stuff and they call for a mopar 8 3/4 so I’m actually open to going back to a mopar rear end. But yah she goes! The PO said it was a 7 second car in the 1/8th mile?
I would think 7 second 1/8 mile would be fairly easy with the drive train. I wouldn't pull the 8.8 unless you wanted to, but there would be no need.
