Paint on engine block 1969 Mach 1 Dearborn 351W 4V
« on: May 18, 2020, 09:15:53 PM »
tried searching the site and can find lots of information on paint type and engine compartment painting, but nothing on the details on painting the engine only. I pulled engine and working on the rebuild. As I reassemble want to make sure detailing correctly. It appears that the engine with intake manifold,valve covers and water pump all mounted are then painted as a unit so gaskets and bolts would also get painted. Are there areas such as around the flat surfaces for the exhaust manifold and the carburetor mounting surface would be masked off and left unpainted. Any other unique conditions I should know about. Just trying to do it right. Thanks.

The exhaust manifolds were on the engine when painted. There should be blue paint on the edges of the manifold flanges as well as unpainted "shadows" under the manifolds. I used cast blast in this area prior to painting blue.

Would help to know when you car was assembled just in case there are some changes present during the year. Migth want to add all your cars details in your signature since you will be asked this often here on the site.

Would send you to another thread but it shows a Shelby so too much do this not that so it would take away from the discussion. Basically you would have a completely assembled engine (with out PS) without the following installed. Note engine plate in place as well as flywheel

- Distributor, wires, coil, coil bracket, spark plug wires and spark plugs
- Dist hold down or bolt
- Water pump pulley/ End of water pump with a mask over where the pulley attached
- Crank pulley or balancer
- Fuel pump, lines or bolts. Only a cardboard formed mask over the mounting surface and hole
- Alternator, cast mounting bracket, mounting bolt or spacer
- Alternator adjustment bracket
- Engine lift hooks/brackets. They were painted by the supplier
- Air cleaner, snorkel, heat shield. All painted by supplier
- Carb and throttle bracket. Note: spacer is painted or has a faded application away from the intake
- Oil pressure sender-
- Breather cap or hose
- Don't recall at the moment the water temp sender but it wasn't painted

Masks placed over the heater and radiator hose connections. Mask over the ported vacuum switch if you car was so equipped if not the plug was in and painted.

Painting of the engine plate fades where the starter attaches to the plate to ensure a good ground. Want to mention that I have seen/found some later automatic equipped cars were the lower engine plate didn't have any paint on them suggesting IMHO the possibility that those were not in place at time of paint application.

Exhaust manifolds got a fair amount of paint from attempts to cover engine behind, below and around them. Burnt off or rusted off fairly quickly you can see fresh engines with glossy manifolds in the factory engine threads on the site.

Thanks guys. I went so far as to have the water pump rebuilt to maintain the Ford logo and correct casting numbers, so it will be just a little more effort to get it painted correctly.

What color is the Harmonic balancer? Current engine had it painted blue like the engine, and the pulley is black. Existing engine also had everything painted solid color, versus the variations from the posted pictures, so that is valuable.

Car was built 3/4/69.
Thanks again

Yes a bit more effort to make it appeared to be painted as a unit so detail to gaskets, edges, hardware and such

Balancer would be semi-gloss black. In the picture below you can see the black where it has not dropped away likely during cleaning or poor surface prep and where it still is visible




A couple of other general pictures from the other side

The Mustang Monthly article on Bob Perkin's 52 mile 69 mach 1 has some nice pictures.

Just for comparison that is a July scheduled car. For the same example I posted above ;)
