It's an HEI distributor out of a later model car or truck. Find a newer
service manual and it will show the connections. If I were you I'd check and
see if it's wired correctly. Your 68 came with a distributor with points and
a small window in the cap to adjust them. It had only one wire going to it.
The wiring from the ignition switch to the (+) side of the coil is special
resistance wire, and there is a by pass wire coming from the starter
solenoid to supply full battery voltage while starting. The HEI set up is
not wired this way.
Someone put a later HEI distributor in it (a good thing). There's a tach
connector in the cap, right next to the power wire. That port should be
plugged on the Holley, I think it only has vacuum off idle. Where is
your PCV hooked to? Congrats on the Camaro. I have a '68 also with a
327. There's an HEI in mine too.
