All painted... To my knowledge, the only thing that was
not painted on the basic long-block assy was the dipstick tube. The fuel pump, heat shields, wire seperators, exhaust manifolds, negative cable, negative ground strap, pcv valve, bellhousing, and I'm pretty sure the oil & temp sending units (I'll have to check on those) all got sprayed...
Of course, someone else may want to chime in on this....
