Yes, analog, the < 300hp model, 2bbl 600-650cfm. Here's what I 
wrote back in 1998 when asked about Projection.

I've been running a 2bbl Pro-Jection system for approx....3 years 
and have definite opinions about it.

Pro: Set it and forget it...... Twice a year (Summer, Winter), I reset 
the mid range and the idle mixture adjusters and run it for the next 
six months.

This is the main reason I went to FI, after 30 years of messing with 
carbs and never having them work just the way I wanted them to, 
(for any length of time, that is) and for me the Holley system has 
worked out fine. 

Pro: Gas mileage increase......an overall 10% increase! 
Quite possibly do to : off idle bog elimination, and smoother throttle 
response allows me to roll on the throttle instead of "stomping" on 
it.

Con: Do not expect Holley Tech Support to answer technical 
questions, actually receiving an answer to "any" question is akin to 
pulling teeth.

Con: The installation kit was mediocre at best, documentation 
mostly right, though vague in many areas, throttle brackets 
useless.

This is a true "do it yourself kit", no one is going to help you. 

Twist all the knobs, make "lots" of test runs , record all results and 
pick what works best for you.

YMMV !

I almost forgot the application. 65' Bcuda, 4 sp, 318 warmed over. 

Daily driver in mountainous area.

There are five adjustments: 
Choke, which uses a temp sensor to determine when to "drop out" 
the fast idle solenoid, and idle enrichment.
The other four, Accel Pump, Idle, Mid Range and Power, are 
mixture controls. Power and Mid Range are highly inter-active.

Correct, not closed loop, could never cost justify the O2 sensor 
option.

AFR meter is high on the "Goodies" list. It took a week of "test 
tuning" to dial in the system. Must have pulled the plugs 100 
times. An AFR would have been super helpful.
