If you mean to try a P+H with the ecm in staurated mode, I've run two TBI
injectors, for a while (meaning an hour or so), in a 730.  Would have been
better to run a 749 since it has two P+H drivers in, so it can fire 4 like
in the Sunbird.  I have run two TBI injectors on a 749 and things were fine,
and can't forsee a problem with that.  I also tried running two sets of 8
satuarated injectors on a 749, with the ecm in P+H mode.  I thought doing a
set second like the ZR1s would be fun.  For some reason the current limiting
or what ever didn't protect the ecm from letting the smoke almost instantly
with that deal.
If you want to experiment with stuff like this, get a spare ecm (for a cheap
price) and figure that you might donate it to the smoke gods.

and harness for my 39 Plymouth and have been researching injectors.

driver. D8 is grounded to D4 for TBI(peak and hold injector(s)). After
looking at the jpg in the archives for the 92 '730 V8 pinouts (BC11 & BC12
inj. drv.) I am wondering what current the driver transistors are capable of
handling.
> the caddy-olds intake I have used a ND 1181281(531C) injectors. I have
contacted the injector Guru in regards to the specifications on these
injectors but have not heard back yet. They are similar to the Bosch style
except for where they meet the fuel rail.  I am assuming they are a
saturated injector. any suggestions as to a website listing newer versions
of these injectors.
