[Diy_efi] dis 90 cutlass v6 3.1

Here's my thoughts on this:

First: all will require some reporgramming of the prom
for best dirvability and economy.

Easiest.  Use a Trottle Body System off something with
a GM six cylinder and the stock distributor.  There is
a very simple circuit to use with the points as the
firing signal.  But I don't have the circuit.  It's
something like a resistor and a capacitor.  Main
actions are a 15 psi pump with return line, a powerful
enough 12 volt electrical system (is the 235 a 6 volt
vehicle?), the spark signal, mounting the throttle
body.  Also using an inline speedometer speed sensor.

Somewhat harder.  As above, but retro fitting an HEI
distributor.  Don't know how on a 256.

A bunch harder.  Going with a system off one of the GM
60 degree, tuned port system with individual
injectors.  The crank position could be handled with a
laser cut plate from a computer aided drafting file.
The plate would have notches cut in the plate with the
proper spacing and sandwiched between the pulley and
harmonic balancer.  Also you wuld need slots to orient
the plate in the correct position, then use a pin of
something to lock the plate to the harmonic balancer.

I like the throttle body idea.
