Painting 500efi's block & heads
 

On the 500efi motors they come black with the Merc Blue top end and accessory's on the front are blue.

My question is would you go back with the Black blocks and heads or the Merc Blue?

The Merc blue is not a high temp paint .

Would that be too much blue on the motors?

If I go with the Blue Whipples I know that would be too much Blue :eek:

On the Whipples the kit gets ride on the water cir on the front of the motor ,so that should clean it up some.


Thanks

Rob

Paint the motors all blue and use the polished whipples :drink: :drink:

Im sure you know, but make sure you strip the old paint well. I have painted 2 sets of engines, one started flaking on the dyno. The next i used aircraft grade stripper and stripped it down to bare metal. Looks great now. I say no black, although with the 500efi pulley setup you cant really see the block.

Re: Painting 500efi's block & heads
 

The blocks and heads have been thru a stainless steel shot tumbler. there bare naked :D

Thanks

I painted one all blue and went back to the black. Too much blue. I like the look of the polished Whipple but do not care for the maintenance of polished aluminum. Either you have to polish it often or it starts looking bad. I made myself come to the conclusion, either its painted or its stainless.

On bare blocks I have used acid etch primer, black engine enamel, and clear coated with Dupont Chroma Clear. That holds up real well. The Chroma Clear works real well on top of Merc's spray can Hi Perf Blue also.

Blue! We pay alot of money to run blue engines. Lots of boaters paint their engines Merc racing blue to try and LOOK like they have the real blue engines! Why go black? It will look asthough you supercharged any old 502 block, and bolted hp valve covers on it. My two cents!

Re: Painting 500efi's block & heads
 

Anybody got any pictures of a blue painted 500 hp motor?

Thanks

Re: Painting 500efi's block & heads
 

Hey Strip,
Mine is painted all blue. Looks good in my opinion with polished valve covers, CMI's and all accessoires painted black. I have stock 454 pulleys (black) insted of the blue 500HP ones.

Re: Painting 500efi's block & heads
 

Well, holly crap, I'm an idoit! I've owned one for four years, wrnched on it, cleaned it, maintained it, and I thought the block was blue. My Very Bad. I should just delet my previuose post.

Re: Painting 500efi's block & heads
 

I am getting two 540's built this winter, and I going to do it all blue. You will still get some black contrast through the hoses and belts. Add some polished accessories and it should look sweet. IMO

Re: Painting 500efi's block & heads
 

I just ordered the Polished 3.3 stage 3 Whipples today from Mark at Precesion Marine . yall are 50/50 on black or Blue.

The only thing now will be the valve covers and pullys that are blue, I think the whipple pullys are black now it would be nice if they where polished also.

Need more input???


thanks
Rob :D

I own a collision center, and have painted many motors. I can tell you from experience, that if you wash your engine parts with soap and water, I use Dawn , and use a two part epoxy primer, you can then base clear with any color you want. I have never had a problem with pealing, even in my hot rods. With clear coats, you will be able to clean your engine much easier and they will always shine like the day you painted them!

Re: Painting 500efi's block & heads
 

I tend to lean AWAY from any of the dark colors especially
black. They absorb alot of light, and lets face it Marine
engines do require some up keep.

So the easier it is to see, be it cleaning them or
changing plugs etc., your brighter colors pay off.

I attached a picture, you can see the light colors radiate with
light. And the dark colors all around the engines steal the light.

Re: Painting 500efi's block & heads
 

strip, sounds a bit boring... how about a orange to yellow fade out that matches the exterior colors of your hull (aka hole) i'd fade from yellow down to orange. thet benifit of a lighter color is you can spot any leaks easily, i't will look trick as h*ll, everyone will know it's not a stocker, but a custom engine, hugetime will be green with envy :D , young big breasted hotties will want to mount er um meet you :bunny: . almost any good quality base coat clear coat paint product will handle the heat. (put a thermometer on the exterior surface of a black car on a hot summer day) the key is the use a acid wash self etching primer, then a good 2 component primer, scuff with 320 grit, then your base and your clearcoat. then sit back and pound a few cold ones :drink: . becreative bro. just my .02. ratman. oh almost forgot... porn rules :cool: :evilb:

Re: Painting 500efi's block & heads
 

Rob..... The blue ALWAYS looks good, but if you want to be a little different, try a wild color.
Last summer we redid the power in a 50 Nortech, triple 850 S/C 540's. The owner wanted the engines painted REAL wild. The boat has every color you could ever imagine in it. So we painted the longblocks and valvecovers a tangerine orange pearl, pearl white pulleys, blue carbs, green brackets, yellow accesories, some things were purple, man it was real wild. He LOVED it !!!
But the orange tangerine pearl looks real good, but, you need to have orange in the boat somewhere.
We got the idea from the painter. He has a 8 second 69 nova that he runs in that 10.5" tire class, and he painted the whole car that color. The engine too. It looks great.
My brother has the pics of the nova/eng. I'll get him to post them later. I don't have any pics of the engines in the boat, but I did find some of the boat..........Frank

Re: Painting 500efi's block & heads
 

Frank now thats a paint job :eek:

I have the 500efi blue valve covers. I guess I could do some thing with them?

I wonder how a different color would look with the polished Whipples?

Re: Painting 500efi's block & heads
 

I say do them blue, and leave the valve covers with that polished section on the top of the valve covers alone, that and the polished whipples will give a super clean look to it. Maybe call the boys at VSI and get some braided lines. If you can polish the pulleys cool. OR depending how deep you want to dig into the change purse. maybe billet pulleys with serpentine belts??...Rob
