Super Six fuel mileage

Between here and SS.org I bet a robust solution could be achieved.

I'm more of a hands-on type of guy so I'm always looking to do things the hard way ;)

Yeah Slant6.org is where I have been reading up on a lot of stuff including how to mate a T5 from a 4 or 6 cylinder Mustang but the bad part is a rear gear change will have to be done. Can you think how much fun that /6 will be with EFI and 5 speed?
