Supposedly a 4BT is 700lbs dry w/o an intercooler, while an LS2 is supposedly at ~450lbs w/ accessories, so we're looking at a ~250lb more weight at least. There's also going from ~400hp/3000lbs to ~150hp/3250lbs, so we've gone from a two seat sportscar to something w/ about the same power to weight ratio as a new Prius that gets the same or worse BTU adjusted mileage and can only carry a couple people. To each their own I suppose, but if I'm going to the trouble of finding a vette as a donor chasis, I would at least want it to still behave like a sportscar. I think a C6 w/ a blown engine, preferably head issues, along w/ an AFM head, would be the lowest cost/best performance/easiest solution, unless of course the owner wanted to run WVO or something, then they have to go w a diesel.

Um, at 0 mph, there's no context for energy efficiency, since the vehicle isn't even doing anything, unless of course it's just idling, in which case the driver is seeing 0 mpg, which is as inefficient as we can get. In terms of driving slower than traffic, there's no logical paradox, just a desire for lower transportation costs and/or greater safety in terms of accident avoidance.
