I watched video where some of the heavily sponsored guys on Horsepower TV took a Ford 300, making 80 Horsepower and exceeded 400 Horsepower with lots of mods. It was educational. They did it in stages. The last stage was ridiculous. They custom fabricated turbo plumbing. If memory serves the intake side went under the oil pan. It won't work in a vehicle, but it did work on am engine stand. I read somewhere "After the Nuclear Apocalypse there will be cockroaches and Ford 300's still living."
I've got the want to find a Tacoma, or 80's "Toyota truck" and stick a Ford 300 in it with a 5 speed manual.
