I have a 65' C2 327 a little over stock. Can say i have a over heating issue or not. Gauage says yes, infared gun says no!! Also i just recently installed a Petroix111 in stock diss tri ter . So today, in Il. Temp around 80'. On highy way stays right at 180! Got off highway. Temp went up say 190 ish. And all off a sudden engine started buling, chocking dying !! Had to continue pumping gas pedale tring to go 5 mph! Had to get to garage 5 miles away, kept pumping and it finaly straightened up and ran rite. Got to not my shop and no tools but got it off the road!! Any thoughts please??? Sorry for ranting!! Lol
C2 gauges can be highly inaccurate usually due to sending unit.
Sounds more like a fuel problem. Check for vapor lock and put a heat isolator plate under the carb.
What he says..........You just got a long slug of air bubbles in your fuel line that had to be worked out. I put asbestos sleeve over critical portions of my fuel line but do carb gasket first.
did same thing three times coming home!!!!! Stopped and removed breather top and wife tried to start and very little gas coming into carb!! Stopped at auto zone, tried to get fuel filter. No chance! Lol. Sit there maybe ten min. Went down road 1/4 mile , did it again! Was very hot out ! Pumped carb. And had fuel, but wouldnt then starf, fuel like quit squirting!!!! Waited say twenty mins and left out. Only drive 60. Made it home!!! Not sure what the!!! Have had several time of hard starting !! I had installed new. braded fuel lines at carb(Holley 650 ). New Petronix 111 module and the low ohm coil they recommend!!! .
1. Did this problem start after you added the Pertronix?
2. When you say there's very little gas coming into the carb, do you mean that you're not seeing a fuel spray when you open the throttle? Or do you mean the fuel level in the float bowl is low?

Is the coil powered through the ballast resistor, is it overheating?
How about a couple of engine pictures with and without the air cleaner showing how the fuel line is routed, any fuel filters, and the carburetor? Sounds like vapor lock.
180* is normal and 190* is not over heating so don’t worry overly much about that
Pertronix 3 has been working for me for several years. When Pertronix systems have troubles. It just stops. No chugging, no running rough. Just Off. That’s part of why many don’t like it.
The flooding due to fuel percolation or just boiling and going to vapor lock fits the symptoms. And it doesn’t always require Engine Overheat to boil the fuel.
the next time you drive, pull over and pull the air filter as soon as it starts - look to see if fuel continues to drip into carburetor bowls.
a heat shield is also a good idea as is using Gas without Ethanol.
checking for a stuck inlet needle valve or stuck float/ high fuel level in the front fuel bowl…
also wiring the heat riser shut might help too as it helps the carb warm up in cold weather…. But may lead to overheating it in the Summer
let us know what you find. Also a little background would help. How long have you had the car, any recent changes or other problems etc
Fuel pump might be failing to keep adequate gas flowing into the carburetor float bowls.
Also, the ignition coil might be close to giving up the ghost.

I agree with the balance of your response but you are incorrect in your above assertion. I followed a friend home with failing Pertronix. In this case failure mode was erratic swinging timing wildly between advance and retard. The car farted, popped and pinged, couldn't make it up his driveway. I agree they often fail as if an incandescent bulb, but not always.
I agree that in ANY car with Pertronix and a running problem the Peronix is suspect. The old adage that 99% of carb problems are really ignition problems does not apply in the case of Pertronix. Remove it and try with points before monkeying with the carb and fuel pump.
So i have driven some, not interstate with Petronix 111. Till yesterday that is. , was hard starting, after shut off Talked to Petronix tec. This morning. They said sounds like possible coil! The coil is there coil, Flame thrower. .32 ohm. He said if mogule it would not run!! The ballast resistor is removed, i changed the intake manifold( original had a crack at temp sending unit(i over tightened!! ) installed a Edelbrock 2701used polished. Not so nice!! Has a Holley db. Pump(not sure of size😩it was on engine when i bought the car! Engine seems to heat up in slower stop go traffic! Scares me some not sure jf it was vapor locking yesterday or what!! What carburetor gasket is recommended. Thanks
I use one of these. It’s about 1/4 inch thick so since you don’t have stock intake best check hood clearance as you may have to run a bit lower air cleaner.

Many who have been through this with Pertronix (me included) restored the ballast resistor in the coil + side wire circuit to resolve this coil over heating (over voltage) stalling problem (regardless of what their literature and advice state).

My '64 has a 4150 650 vacuum secondary Holley with a 1/2" phenolic spacer on an Edelbrock Performer EPS. I had to go to a 2 1/2" K&N filter and then grind a small bit on front lower edge of filter base to clear the hood by tilting slightly forward.

Erratic running!!!!
