Here's some info for clarity... I mispoke when I said Nascar, it was Roush Yates that this was delivered to... I simply live in "Nascar" country... but once I did some research, this is what I found... excuse me for mis speaking.
The company I contracted with is called Tempest Aero Group, feel free to look them up -
https://tempestplus.com/product/spark-plug/ they make aviation-grade products... clearly working on some prototype stuff, including for my truck... will keep you guys updated on that.
Yes, it had that many miles, and the engine was tired, and hanging on by a thread. The rest of the truck was actually gone over by the dealer, and given the stamp of approval. Had everything checked and serviced. If they found anything too wrong with much else, I likely wouldn't have dumped the crazy money for a new engine.
I couldn't get rid of the truck as I still owe on it, and it's not worth diddly to anyone but me with this number of miles. Had no choice but to repair it, figured best best was brand new from the dealer.
I am very proud of the amount of miles I got out of it also... with this 3 year, unlimited mile warranty they gave me, and the money I paid to get the work done, MANY more miles will be put on it. Will keep you updated on that. I have a feeling it will get near a million miles in the next three years.
