Well I came across an article discussing Max Lagod's work with international designing the dt466. Having a family member that worked on this project as well, I was able to dig up some more info. I talked to my family member who didnt remember the f-100 but put me in touch with some grey beards who owned speed shops in the 90s that competed against the truck. One said he knew where the truck was parked after Bill Jahns moved onto his Bonneville project after the block split for the third time. He asked me to call monday once he inquired about the truck to the owners over the weekend, just waiting on a call back. Further down the rabbit hole...
