I'll be stuffing a 5.7 in my '73 Dart, but will not give up powersteering!
For that to happen however I need to switch over to a power rack&pinion system.

A Megasquirt3 will be controlling the motor. Fuel will be LPG fed through vapour injectors.
Not sure yet how the Hemi will interfere with the brakebooster.
Behind the Hemi will be an A518 overdrive transmission.
