Like any good project, the key is in the upfront costs. This project requires that I find a distressed Corvette I can pick up cheap. Just gotta keep looking.

The 'Vette offers one other thing: I can easily score 2.73 gears for one as all automatic C5 and C6 'Vettes come with 2.73 gears. That gets me down to just under 1100 RPM@70 RPM. Drivetrain nirvana.

The Cummins 4BT3.9 is about 150 lb heavier than a LS2.

Driving slow is a logical paradox. You drive because you want to get somewhere faster than a walking speed. The most energy efficient speed is zero - you simply don't go at all.

I like to maintain at least a foot in the mainstream camp, but I drive so much that anything over the limit for as much as I drive guarantees you a ticket. Bad enough that so many jurisdictions are writing "revenue tickets." I don't wanna give 'em any more, but I do make the trip for a reason.
