Maybe this is a noob question and I should know better, however -
So the LSX and most modern V8s are know for making both power and retuning solid fuel economy numbers. My understanding is this phenomenon is due to great improvements in head efficiencies and the addition of modern overdrive transmissions, both manual and automatic.
In many 351W builds I see owners reporting single and low teen digits on their fuel economy. All of these engines are pushing old slush boxes with carbs (controlled fuel leaks).
Is it unreasonable to think a 351W with +12:1 compression, aluminum heads and something like a T56 could make both good power and get good fuel economy? I would be looking at running a Victor Jr style intake, port injection and MS2 ECU.
If not, what is the primary barrier to getting modern style fuel economy?
