Mike,

FWIW, When the Magnapulse aftermarket ignition failed on our 77 534
Ford the mechanic replaced it with off the shelf parts (Ford OEM).
The distributor, coil and ignition module were replaced. Wires and
plugs had been previously replaced during a tune-up and the
alternator had been rebuilt. [The new distributor is 6" taller and
requires fabrication of a new bracket for the engine a/c compressor
to move it outboard 2". If your engine a/c is inoperative you might
just remove the compressor and reroute the belt.] Mileage went from a
dismal 3.9 mpg to a high of 6.4 mpg - avg 5.0 mpg flat towing a 2000
Jeep Cherokee. Starting and driveability were also improved.

I recently talked with an auto enthusiast who spoke highly of a
throttle body injector for big block gas engines (i.e. Chevy 454 and
Ford 460). He said horsepower was down slightly but low end torque
and fuel economy improved - just the ticket for a 'Bird. My
wife's '93 Cadillac Fleetwood had a 5.7L V-8 with throttle body
injection that delivered 25 mpg at 75 mph and would top out at 120
mph. Hmmmm...food for thought.
