I've seen some recent pics of motor build ups some of you all did and painted the block? Is there a reason for this or just like a colored block? Does it help with protection and wear or something? Just curious as to why its done and the advantages of it.

Simply put..if you take the time to rebuild you would usually want to take the extra effort to make it look cosmetically better...nothing looks worse than a block covered in surface rust...looks better and cleaner to work with. Also steel will aquire surface rust fairly quickly when uncoated and could cause contamination issues during reassembly.

It's called a tremclad rebuild. Depending on the color you choose you could be upping the HP by 50 or so ponies. Ok well maybe not. It's to tie everthing in to a color scheme.

I am powdercoating mine, awesome finish and it will never dull, chip, fade, etc. I always thought it would be a fortune to powdercoat a block, but I found a really good local shop that will do it for $200.

You can buy your own powder coating kit for a few hundred bucks.

I wonder if you could get your block JET HOT coated. That would be sick.

JET HOT doesnt turn blue when it gets hot, then again maybe the block wont get hot enough to turn chrome blue.

What temperature does the metal of the block get to?
What temperature is required to turn chrome blue?

The only reason I wouldn't try powder coating the block at home is that I don't have an oven that large...
Otherwise, I would give it a try...


I don't see how powdercoating force heat retention, at least not any more than regular paint would.

I doubt if the block gets NEARLY as hot as a set of headers...first of all it huge...second, theres oil and coolant running all over throughout it keeping it much much cooler.

Yeah, I have my own powdercoting setup, but I just don't have an oven big enough to powder coat my block.

They say that Powder coating does retain heat a little more than paint etc, but they make special high heat powders for blocks and headers which are not suppose to retain the heat as much.

the block gets as hot as what thermostat you're using, give or take some, some spots will be hotter than others like right around the cylinders.

I can't remember what type of paint this guy used but he described it as black rough and krinkley looking.He could'nt figure out why he was over heating and after spending a bunch of money it was narrowed down to the paint on the block, so he stripped it and no more over heating.
