I can’t believe that red ‘66 F100. I met the guy online 20 years ago, his name is Randy Honkala. His abilities are incredible. That truck was a show truck with a 482” side oiler 427 backed by a CJ spec C6 with a Gear Vendors overdrive last time I saw it in 2019. He’s now blown it apart and powered it with a twin turbo Raptor crate motor and transmission. He’d already done a couple of really extensive builds of ‘65/‘66 F series with late model chassis, running gear, and interiors with everything working and looking good. I found that he’s doing a YouTube channel. Worth your time to check his stuff out, its pretty amazing.
