I have just done a body lift and got the frame out for sand blasting and paint.
While I am at it I will go through the engine and transmission, both works fine but now is the time to tear them down and and replace any worn out parts.
The engine has been taken out by a PO and the engine block is painted grey, the heads have a different color so I do think that the short block has been replaced, so is there any engine builder that use gray paint on the engines ?

Espen,
How long has this coach been in Europe? Do you know who the previous owner was?

Sir: All 455s were F or Fa cast on the front but if the "F" casting # is on the back of the block above the rear main it is the nickel content. F was the first series with the most nickel content, F 1 casting is second series with less nickel. Goes to F 5 was last series. The early 455s was before hardened valve seats and had "C" heads. The F head was the latest 455 and was only 455 heads to have hardened seats.
The VIN derivative stamping or engine unit number on the left most side of the block, on the driver's side, just below the cylinder head, toward the front. The pad is part of the engine and will indicate the year of manufacture. Rubbing alcohol and Q-tips help to remove the grime and grit from the stamping.

Yes it could be a Jasper, the VIN # is gone long time ago, it has a F block and J heads.

Well it seems the F and Fa castings were not the only 455. L casting is Motorhome. The casting # is smallest. I wonder if that would mean they were the first series cast?? I would be interested in the F casting # on the rear of an L casting on the front.
ID/ Casting

I partially disagree and offer the following information regarding heads...
Generally, heads with valve rotators and corresponding deep spring pockets (3/8" wide retainer rather than 1/8" retainer), have induction hardened exhaust seats from the factory. Some heads are rumored to have the rotators on the intake or exhaust valves only.

Our local engine re-builder will paint the engine any color that you want. He built one for a local GMCer and telephoned them just before painting asking what color they wanted it. The wife answered the phone and she told them how about pink?
She told me the story. I forget what color they finally settled on.
Engine color is not a good indicator of who rebuilt it.

Mike had Hijacked the subject and most would have ignored his question.
Go to bdubs site, go to GMC Parts and Accessories Suppliers, go down right column to Dan Stucky, Click on his name, go down to the last 4 pictures and you will see that he has a piece of 3” X 3” square tubing that is bolted to the rear tree and the same in on the front tree.

As Neal points out valve rotors require deeper spring pockets.
Valve rotators were introduced in some engines starting in 1971.
Since unleaded fuels were being used then those engines had hardened seat areas.

Ah, while we are on the subject of 455 cylinder heads, the 1971 and later
heads, which were designated with the alphabet letters H, G, J, and K, all
had induction hardening to the exhaust valve seats. This was mandated by
the EPA for the use of Unleaded fuel. They either had 79 cc or 80 cc
combustion chambers. Most all of them were fitted with valve rotators on
the exhaust valves. Some also had them on the intake valves as well. On an
unmolested head, you can determine this by checking the depth of cut on the
spring seats. Without anything but a good 3 angle valve grind, these heads
all will work equally well on our motor home engines. If earlier heads are
to be used, I recommend that the exhaust valve seats be machined to accept
a hardened valve seat. ONLY SEATS INTENDED FOR USE IN AN OLDSMOBILE SHOULD
BE USED. DO NOT UNDER ANY CIRCUMSTANCES ALLOW YOUR MACHINE SHOP TO USE
SEATS INTENDED FOR A BIG BLOCK CHEV. YOU WILL HIT WATER IF YOU TRY IT. The
D series heads #400370 produced in 1968 and 1969 had 72 cc combustion
chambers. They will yield, in my opinion, too much compression to safely
use in a motorhome. These heads are also known as the W-30 or W-34 high
performance heads.
If you have an original motorhome engine block, it should be identified by
the casting Alphabet letter "L". These engine blocks were found in
motorhomes, agricultural/industrial, and some Marine applications like
Crusader. Not all marine conversions used the "L" blocks.
