New bb build fuel economy
My first language is Swedich if you dont understand what im writing just stop reading
I had the same thought as the other guy, but I generally give non native English speakers a pass, versus dumbass American youths that don't have an excuse other than poor parents.
So far as the build, rule number one build the car as light as possible. That motor needs to be small block light.
I would focus more on drivetrain than motor. Tall gears and overdrive, and figure out your cruise rpm, and build your motor for peak torque at that rpm.
So then your motor ends up being a low rpm high torque cam, heads optimized for your cruise rpm, and 9.0 compression and that should yield decent fuel economy. The trick with economy is to build your combo around your given cruise speed, instead of building it around a certain elapsed time, horsepower, or sound.
When I worked on Harley's, there was a guy in the shop turning out some REALLY hot big twins that usually had a significant increase in economy because they were just idling down the highway.
