feets, what carb are you using ? have you tailored your distributor curve, including vacuum advance, for mileage now, or will you be doing that once you get the o.d. installed ? are you going to something deeper than 3.23 gears to get the mass rolling easier, then using the o.d. to lower the highway rpm's to acceptable levels ?
Right now the engine is in pieces.
I plan on dropping a FiTech system on the car and setting the distributor for best torque/mpg.
