Engine Block painting
 

What is the best way to prep and then paint a Chevy engine block? Looking for info on primers, types of paint, correct colors, etc.

It's a real pain to work with, but I love the POR products.

If it's a fresh rebuild, the prep is mostly done when its tanked to clean metal. Otherwise, its tedious work to prep an engine. A lot of cleaning and scuffing in all the nooks/crannies.

We paint engines with pretty much the same process you would use for the outside of the car, and with the same products. Epoxy/etch, sealer/primer, BC/CC (sometimes single stage) with SW product.

Dont know the exact terminology or product #s, I dont do the paint/body stuff. https://www.yenko.net/ubbthreads/imag...lins/blush.gif

IF you are over restoring a car then by all means go with the primer ... epoxy combo... however if you are looking for an authentic restoration then a light covering of an original type product from a spray gun is how they were done at Flint and Tonowonda. If you look at orignal unrestored cars they have minimal paint on the engines.
Here is a link to pics of a very low mileage LT1...

I understand the lighter the coat of paint, the longer it will last because it allows the heat to evaporate. If you load it up with primers, base & clear, it will peel off quicker. Any truth to that?

true that.

No primer was used...
Just get a can of hi temp engine paint, and go for it.
Make sure the surface is clean.

No fancy paint or anything - later on, it makes it easy to touch up too. https://www.yenko.net/ubbthreads/imag...lins/smile.gif

All good info. I was either going to simply spray a hi-temp paint or go the primer, base coat etc route. I will probably just use a can of hi-temp paint.

I use plasti-kote engine enamel and gray engine primer. just a light coat of primer and you wont get the cast bleeding back through the paint.

ENGINE ENAMEL and Primer
Resists Temperatures up to 500°F (260°C).
Race Tested.
Will not Burn Off, Chip or Peel.
Oil Resistant.
Color Choices are Exact Matches to Original Engine Manufacturers Standards.

How does powder coating look? A local shop will do engine blocks, heads, etc. It should be fairly durable.
