70 to 90 psi cold while at higher revs is not uncommon
or unwanted. Mine usually runs 75-85 cold, 60+warmed
and drops to 30-40 at idle warm. And like Nigel, Punkin' is
far from stock. (actually I find myself tracking your problems,
as we share very similar setups ) :-)
If you don't like the extra gauge in the cockpit, (aesthetics,
possible leaks on the carpet, etc, etc. ) there are oil pressure
switches that switch on/off at different pressures. You could put
a small plumbing 'T' on the side of the engine where Dave hooked
up your gauge and install a racing style oil pressure switch that
toggles at say.... 25 PSI to light up a second idiot light.
( a lot less conspicuous)
Another option (I prefer) use a second '3 terminal' oil pressure switch
(used to control the run on valve in late models, ) but wire it to
disconnect your ignition if you don't have pressure. This also has the
added benefit of not letting the car start until oil pressure has built up a
bit.

Nigel is back on the road and with his hideously ugly after market oil
pressure gauge hooked up and working. I can see now that I really want to
get one of those nice combo oil/temp gauges-or at least a decent looking
oil. the DPO -the one before Dave put it in and it has a decidedly shag
carpet look to it-and it's over the glove box-so it's not really easy to
see. I guess a new wood fascia would be in order too...
Anyway!-the oil pressure at idle, with the car warmed up is 30-40 while the
pressure at speed is about 50-60-a wee bit higher upon excelleration. This
is not a stock engine, so, your pressure may vary.
Had an interesting chat last night about tires-still sorting it all
out-thinking of switching from 185/75/13 to 185/65/13 Yokohama performance
tires. I've never been terribly happy with the tires on Nigel, and do a lot
of fast freeway driving. I want a feeling of a bit more stability...
