Paul Spotts built the engine, new water pump, clearanced the water pump plate, has a stock fan shroud, new clutch fan, upper and lower baffles, new radiator, the thermostat is 180 I believe. Last year, even in 90+ degree temperatures, it ran around 190 all the time. The crossovers in the heads were aluminum filled.

When it dies, it is a hiccup and stall. When I pump the accelerator when the car is stalled, and then try to start, it wants to start, and then hiccups again. It definitely feels fuel related and not spark. It is the in-carb fuel filter, and it was clean. I have to figure out how to add a temporary fuel pressure gauge. The entire fuel setup is all new stainless lines that I do not want to damage.

Sounds like it’s flooding or vapor locking……I would double check your float height and make certain your float and needle/seat are in good condition. Set your float height a smidge lower than the specs for your carb…. Run it, and see how it responds
