That is fantastic. I was looking at doing a 4BD1 swap into my 66 C20 but love the specs of the 6BD1. Are you able to do a video of how it fits in your F100 and any challenges you overcome please?
Yea 6 cylinder is a much better option, smoother, big gains in torque, same amount of work. I originally planned to make videos of the whole build, but my phone screwed up and I lost most the footage and photos, but I can make a current video of how it is, what I did etc sure
How well has that 6bb1 held up to the turbo? I’ve heard that adding a turbo to these isn’t a good idea without the piston oilers and different pistons.
Nahhh handles it just fine. Keep an eye on egts and oil temps, as long as you keep the tune safe, they don't have any issues being turbo'd. I rebuilt this one back to factory spec too, factory pistons, liners, rings and bearings. This engine has done over 30,000 ks in my 79 ftruck carrying our camper, trouble free.
