I have 69 F100 4WD with a 360, manual brakes, and a fairly lame power assist steering. I the 360 rebuilt by a guy who turned out to be a liar and an idiot, so it took longer and cost more than it should have, but with a mild cam, and Edelbrock intake a 650 CFM 4v it is now running fairly well.
The front end is a little different because of the power assist - the tie rod is reversed (long end on the passenger side) and it has an extra hole in it to attach the power assist.
I am having a pretty deep restoration done on the body right now, but while the guy is a craftsman and does beatiful work (Ronnies Rides in Carstairs), he doesn't do mechanical. I'd like to find someone that can do some work on the front end (switch to power disk brakes, proper power steering, and some suspension improvements) who has experience with older trucks.
try some of the local 4 x 4 shops. they should be able to do those modifictions pretty easily. stick to the ones that are more into the true off road stuff then the ones that sell bolt on doo-dads and appearence packages for the posers.
