This post makes me think you're not serious. I'm all for American V8 power and durability and I wish mine were more efficient, but I know 50 mpg and 800 rwhp can not be accomplished using the same engine with the same heads, cam, injectors, intake, tune, etc.
I read about a guy who had a duramax in an sn95 who would drive to the track at low boost and fuel getting 35 mpg, install slicks, crank up the fuel and boost then run 9's. Then he'd cut the fuel and boost and sip fuel on the drive home. That is plausible.
I'm planning to swap a few parts on my 302 that, along with some subtle aero mods, will hopefully enable me to hit 30 mpg.
But 50 mpg is outside the realm of possibility.
