Get You A Allison Aircraft Engine LOL

We used to go watch the UH boats when they came to Texas many years ago. When they brought in the "hair dryers", we quit going. Of course the the Allisons are probably harder to find these days, not to mention finding parts for them. There used to be one of the boats down in Seabrook, TX many years ago (at least 50), and the warehouse it was stored in had a plethora of parts that included anything they needed to build one. The owner told me he had 10 complete backup engines at the ready. The warehouse is long since gone and no one can tell me what happened to the boat or anything that was stored there.
