Hey guys I’m having an engine heat soak issue. I just put a lot of money in my car and I’m having a heat soak issue often I drive it. I put the best stuff in the car and the temp stays great while driving but when I shut it of the temp will rise to 250-260 and won’t hardly start or run. I do have the complete Holley sniper kit with hyperspark. Runs amazing it’s only after I turn it off and try to restart often a few minutes. And suggestions on a fix for this? Btw it’s a 455.
