Big Block Truck Headers/Exhaust manifolds

Looks like it's the same as my '77 motorhome engine as far as mounts and manifolds go. I wouldn't be surprised if the motor mounts would bolt on the truck but they may make the front of the motor set about 1" too high. No big problem as I have an extra set. I'll check my '75 4x4 and see which oil pan it has. I can't remember if it's a center or rear sump. I should have the correct pan and pickup extra. My '75 has a center dump manifold on the passenger side also but your rear dump may fit on the truck. I can't remember anything in the way. I have an extra center dump manifold if you need it, though.
Just let me know.
Thanks,
Dallas
