I have a 1936 ford vintage modified v-8 with a wheelbase of 112". I'm wondering how much caster angle i should have on the front axle (solid ford I-beam)? Is there a rule of thumb or range? I'm assuming 5 deg should be fine? I'm running man steering but i was going to put in power. If i put in power would i need more or less caster?.I heard with power i should run more.

We run a straight axle vintage modified in the midwest. With power steering we run 8 - 10 degrees. Never ran it without power.

run enough caster so it goes straight down the chutes, you don't want too much or you won't be able to steer it with man. box.That's why they ran skinny front tires back then. With power, then go to 8 or 10. By the way, it is all done off the right front.With your ford axle, the pins are the same, but it is good to get in the habit.Tube axles have caster built in.

I agree with most of the last post but caster is not built into tube axles. Caster is adjusted with the radius rods on a tube axle. Even if it's something like an old Chrysler tube axle it could still be adjusted with the clevis at the end of the wishbones. Now if you want to talk your basic old solid straight axle they were set and you can either bend the radius bars, but more preferably you just drop the back ends of the radius bars down to gain caster.
