I am just repeating what Tom told me. He said he can no longer get cores. My guess is that Tom was not making these up one or two at a time so I imagine he was not looking to buy cores one or two at a time. Just my own guesswork of course. That and what is unsaid, he is 80 now. Would he build one if he had a decent core, the custom shaft he used, and other parts, I don’t know. My sense of it when I purchased the HEI was that mine was the last he had on hand, and the last he was going to have on hand. But ya know, ya never really know, lol.
So Jerry, what is the issue with the Mopar triggered HEI? They seen durable enough.
