The only aero I've done is: Add a front air dam Smaller front tires allow it to sit down low
Other efficiencies include: Electric fans for engine cooling ( they never run at highway speeds) Manual trans 2.56 gears ( no overdrive)10 bolt 8.2 rear no power anything.
The carb is not a conversion. The 2305 is a real progressive 2 bbl made that way. Both barrel get the accelerator pump and the power valve only feeds the primary barrel. It also has annular discharge boosters.
No strip time with it. Am looking at buying a G-Tech performance meter. It could be very handy.
