Block is painted. According to Pete (BB V6) the blocks were painted in one go when the block was finished. I painted the block without the intake manifold in order to fully paint the intake manifold and valley cover area. VHT Ford red engine enamel (Duplicolor is the same) was used to paint the engine. 2 light coats of primer and 3 final layers of red. as you can see freeze plugs are only pushed in. Will change these out for new zinc-plated freeze plugs to add some contrast. Will see how it looks.

It really is pretty much identical to the GMC red, but the picture doesn't really show it due to the gloss. It still needs to fully bake when the engine is fired up. That will reduce most of the gloss.

Need to paint and install the last parts (e.g. dipstick tube)

The oil pan, timing cover, and water crossover will be taken from the 305.

Now to install the engine: SBCs use a plate with a lifting eye mounted to the intake carburetor bolts. Due to the weight of the V6, I don't really dare to do that. I figured to make 2 adapter plates that bolt to the cylinder heads, using the intake bolts.

Curious about what you used as mounting points to lift/install a V6?
