What color was the engine in 1981 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi Y'all. I'm restoring a 1981 GMC 1/2 L/B 4x4. My question is what color was the engine back in those days. Heck I worked at a Chevy’s dealership in California for 18 years. But for the life of me I can't remember if the engines were black or blue. I guess I'm getting CRS
Thanks Bill

i know my 83s block is blue... dunno if the 83 and 81 would be the same color though i would assume so.

Great thanks for the info

Mickey_D · 02-24-2008, 10:34 AM

My '81 the BLOCK is black, but the VALVE COVERS are blue.

I can double check in the morning, but I'm pretty sure I'm right.

[EDIT] Thinking about it a little more, I don't think my block is even painted.

BowTieOgre · 02-24-2008, 10:46 AM

My '80 block is also black and the valve covers are blue.

Low&Slow83 · 02-24-2008, 10:55 AM

i guess that means take your pick lol

Check out the 1981 Chevrolet pickup brochure. Page 10 shows an engine decked out all in blue. Im not saying thats the way it was...im just saying.

i believe, dont quote me, that 1984 they switched to a black motor.

So, your 81 would be blue. Does your motor still have the french locks? becuase if you still have the french locks than you might have the original motor, but if no french locks your motor probally has been swapped or out.

Well now I know why my engine is Black & Blue. For some reason they sent a few out with a black block and blue valve covers. I bought the truck from the original owner and swears up and down thats the way it came from the factory.

Thanks Y'all

Malo83 · 02-25-2008, 10:43 AM

My 83 Silverado is all black.

ghettocruiser · 02-25-2008, 11:21 PM

My '82 had an all original, all black, all 305. The valve covers were blue though.

77gmcjoe · 02-27-2008, 12:12 AM

We had a couple of GMC duallies, an '82 and an '84, both bought new. The '82 with a 350 was blue, the '84 with a 454 was black. I remember reading in magazines at the time when they changed colors, but I'm not exactly sure what year it was. I can't say that I've ever seen a factory two-tone engine.
