Need Engine Painting Advice
Thanks, Tim
I used Eastwood "One Shot" paint for the engine. Two part paint with hardener that's good to 300*, that sprays or brushes on. No brush marks, and really hardens after the first heat cycle (start up). I've done both...spray on and brush. Brushing eliminated extensive masking & dis-assembly on installed 350. Spraying bare 400 block came out near the same as brush.
350 after 2K miles

400 freshly spray painted

I painted the motor of my '65 while still in the car but than pulled the motor out of my '78 to paint it and it's MUCH, MUCH easier to do it out of the car and it's comes out better also.
As far as covering the holes, I used wadded up paper towels to stuff in the exhaust holes, tin foil to cover the valves, and i also removed the aluminum intake to clean that seperately so used painters tape and masking paper to cover the valley.

pulling the motor itself wasn't all that difficult once you get over the intimidation factor of never having done it before.
If you still insist on painting the motor while still in the car than realize it's a lot more difficult and much more difficult to do. You also want to make sure you mask off EVERYTHING else in the engine bay and the body so that you don't get overspray on anything.

After painting the block itself, I than masked off the rest of the motor to paint the top mounting surface of the heads silver to look nice after reinstalling the intake since some surface area of those show past the edges of the intake.
this picture will give you an idea of how careful I masked off the rest of the engine bay to protect it from overspray

BTW, the body was completely covered in plastic to protect that also. The red you see in the lower corner was a fender protector, not the car's paint
