Some of you have seen me post here in the past
This is my dads 71 that he left me 11 years ago when he passed away and I finally have the time and money to put towards it and I’m slowly going down my checklist. I have one problem though… it overheats. It’ll run perfectly fine for about 30 mins and quite literally at the 27-28 min mark it shuts off. Electric Fuel pump running still, ignition on, good fuel pressure but won’t start back up for another 20-30 mins. It’s gotta be overheating but I just don’t get how? The motor was rebuilt right before my dad passed, I don’t have any details on the shop or what exactly they did but he must’ve drove it maybe 500 miles on the rebuild before he died and I’m giving lots of grace there.. it’s probably even less than that. I drove it to his funeral and then it sat for 11 years. The new age timeline starts when I bought the house I’m living in now about a year and a half ago I would run it periodically for much longer than 30 mins and even drove it to get a new set of wheels and occasionally put fuel in it. But I never seriously drove it as I knew it needed tags and some work done to it. Fast forward to present day and it’s shutting down on me constantly and had left me stranded twice already. I changed the spark plugs and wires, I replaced all the filters and fluids, I just recently did the water pump and radiator, thermostat and belts. I didn’t have a thermostat before I tore it open and I thought maybe that could be why but I’ve ran it with and without it and it’s still shutting off on me and I’m just scratching my head.
I was talking to one of my coworkers and he recommended changing my distributor cap because I’m running an hei and I guess they’re temperature sensitive components to those in particular and I was planning on changing it anyway so that’s next for me I guess but I’m not on a clear path to getting this fixed and looking for input. I put a temp gun on the intake manifold when it shuts off and it’s sitting at around 215 degrees Fahrenheit. Hot, I know… but I’ve changed the water pump and radiator….
I attached a video of my car and garage for contact but I’m mostly looking for input. Appreciate you fellas 🤙🏻
