I have a 6.0 swap I'm finishing up and I can't find any dual pass radiators with a 1.25 in and 1.5 out does anyone have a source for these? I need one by Wednesday.
Along the same lines do you delete the coolant that runs through the throttle body? I heard that was to warm it? Or do you run it back to the radiator somehow?
The ports on the front of the heads with the little tube coming out. It lets steam and any air escape from the motor. There's several different ways people hook them up, but IMO the best way is plumbing them back to the top of the radiator.
