  550 cc/min = 0.1453 Gallons.  So 0.1453 Gallons * 60 (minutes) = 8.718
Gallons/ hour x 6 (lbs/gallon) = 52 lbs/ hr.  Or a 550 cc/min
injector would
flow approx 52 lbs of fuel if it flowed wide open for one hour or
52 lbs/hr.

for the NA engines the stock injector is the 460 cc/min (sometimes they
varied a bit around that figure)
460 cc/min =  0.1215191gallons so performing the same
calculations = 7.29114
gallons/hr x 6 = 43.75 lbs/hour

Ed.
Thanks. I follow that. So with 4 of these 550cc suckers going full belt I'd
be capable of expelling  52/6 * 4 = 34.67 gals/hr. Seems a bit excessive!
Also - does fuel pressure factor into the equasion?
