Check it out well. Like any modded vehicle, it’s probably been beat on. Quality of work on that sort of vehicle usually leaves a lot to be desired IMO. (wiring, lines run helter skelter, stuff rubbing/chaffing, etc)
It has a lot of good parts in it according to the article.
In real life, I’d be surprised if it made over 800hp fuel only with that injector/hpop combo.

i'd be looking all over youtube for the video to see if the owner has videos of it out there.

I am sure it was used as it was intended which means it was beat on. I am just wondering if there are any tell tell signs of a failing engine or injection system. Like cylinder contribution and what now. I know that with tuning and big injectors these test can be effected. So any real in depth methods for checking it out will be useful.
Thanks

Seems like this truck gets bought and sold a lot... I have seen multiple people makes posts about buying this same truck over the years

Looks fun for sure!
