Nice truck for a survivor. I've had a few like it.
My 2 cents, the brake pull can be misadjustment on
left front, the wheel cyl sticking out, or contaminated
shoes.
You said the gear ratio was a 4.56. I found mine all came
with 3.73's in the 12 bolt axle, stock. Yours may be the optional
gear ratio.
When I tired of working on the supplied carb, I took all my beverage cans
in and bought the clifford Research weber carb kit with intake and header.
Pricey, but worth it, in the long run. May take a few more cans on your
budget.
The hole in the side of your valve cover is supposed to run to the air cleaner.
I tee'd it in with the PCV line to the manifold next to the carb base, with a
grommet and 90' fitting. No leaks or pressure issues. Your engine looks like mine, a '73 250. The serial # should be down by the starter on a machined pad.
Mine is a '65 1/2t short step. I'll get a thread going on it and the '65 1502 series shortly
Sorry for long wind. Was holding my breath while reading the thread.
