The HEI is pretty straight-forward to wire. No ignition resistor. I don't
remember it well enough to tell you without looking at picture, and I'm sure
by time I get home and find a picture someone else will have answered that
question... If not, I'll explain tonight.
What HEI did you use in your 270? I have a 270 and have thought about
putting an HEI on it, but haven't determined what distributor to start with.
One of the terminals on your HEI is labeled tach. If you have it wired
correctly a test light connected between that terminal and a ground should
flash as the motor turns. I think the terminal on the far side goes to
power, and the one in the middle goes to ground. But I'm not sure I
remember that correctly, and it assumes the terminals on your distributor
are the same as those on an older V-8 HEI. I think the later HEIs are more
complicated.

Getting my new engine started from scratch with a HEI dist and coil.
Looking to wire up ignition only just to ensure the engine is running OK
prior to installing any sheet metal, etc. I'm using a single wire
alternator, GMC 270, 12V system. I'm starting with no existing wire. I
have a new harness but don't plan to install until further along in the
project. I believe I have the basic ignition hooked up correctly. Engine
cranks over OK but doesn't indicate any oil pressure, glass bowl on fuel
pump not filling and doesn't appear to be any spark. Even if out of time I
should have spark. I've hooked up some cheap gauges, oil, amp, temp, to
monitor the vitals.
Next move is to try priming the oil pump with the drill process, right?
Shouldn't my fuel bowl be filling after cranking over several times? I'm
using a gas can and filter to feed the pump.
Does anyone have a simple HEI diagram?
