Roger,
2 - 2 1/2 lbs. is all SU's need. Get a regulator and a guage. Mount
the guage on a "T" downstream of the regulator. The regulators with the
numbers on them aren't all that accurate.
I have to ask again........Should this 79 1500 with SU's and a couple of
thou skimmed from the head still be timed to 10* BTDC?
