Back in the late 70's early 80's we didn't know all the "details"...
Ran a stock type engine (cast pistons) with a NOS brand 100 shot plate.
Before- the car (duster) ran 13.70's at 102 for a year, week after week, drive in, run.
After- 12.60's at 110, drive in run, drive home,,3.55 gear, capped up, street tires
....always ran 7psi fuel pressure...got about 7-8 full runs per bottle.
no electronics, just mashed a button when I left. Never any problems
Engine came out in 86 and is still on a stand over in the corner...
