68-69 OAI Hood Insulation Delete
I know that the 68-69 W-30/W-31's are not supposed to have hood insulation, but does anyone know specifically where this is called out for in any factory documentation? And does anyone know why? Doesn't save any appreciable weight - maybe it was to give the ducts a little extra clearance?

Hi there,
My original 68 and 69 W cars both have hood insulation?
Anyone?? Steve M will know??.
Cheers,
Sam

My assembly manual says:
398896 - INSULATOR
(EXC. 3100 & 3200)
I believe that the 3100 and 3200 references F85 w/L6 and F85 w/V8 respectively.
There is no reason they would leave the hood insulation off for duct clearance as the AM shows the ducts are clearly below the level of the top of the air cleaner. If the air cleaner clears the insulation the ducts would too.
Who told you W-30's shouldn't have hood insulation?

When I first restored my 68 Hurst, I took it to the Nationals and had points deducted in the judging because "all W cars should not have hood insulation" -even the 68-69's. When I argued the point, the Badgleys told me they have the documentation to prove it so, but I have yet to see it. There were 5 68's at that Nationals (1999) and mine was the only one to have it so I thought maybe I'm wrong about it, but I could never find anything in the assy manuals about having the insulation removed.
BTW thanks for responding to my post.

Well Badgely's certainly know their Oldsmobiles, but maybe they were saying that Hurst Olds' didn't have hood insulation, not that all W cars shouldn't?
Maybe Doc stripped off the hood insulation before putting the 455 in?

My 68 H/O didnt appear to have had insulation ever glued to the bottom & I also had the legendary "X" chalk mark. I can dig up the photo of it later if anyone is interested.....
Not claiming to have the difintiive answer. We may never know for sure. There a few "undocumented" mods on the Hurst cars.

I'll head over to the garage to check my 68 Hurst to see about the hood insulation and the X?
As I posted before, both my original 68 and 69 W30 cars have the hood insulation.

Sam, please let us know what you find. Also, any firewall markings. Mine was unmolested when I got it and did not have any square colored letter stamps. It did have some very sloppy E & C letters handwritten in a white ink - mostly covered by the evap. box.

Here are the images of the hood markings on my 68 H/O. The underside of the hood had a thin coat of some cheap black paint sprayed on it at some point and the hood was tweaked bad enough that I didn't use it in the resto.
Was bored one day while the car was at the body shop and decided to see if there were any markings.
The black paint scraped/flaked right off and I found the "X" as well as a "5".

Sorry, but this has only come up about a million times before. Every BBO is completely identical externally and sits in exactly the same place in the engine bay. There is no difference between the 400 and 455.

See, how hard was that?
I'm sorry for not knowing everything about each of these motors and I'll assume lots of people on here are new to Olds (or Hurst Olds) or not as obsessed and would like to learn and participate in an interesting conversation.
Frankly almost every topic on these forums has been hashed over and over.
Maybe it just be a searchable database so we dont upset the people that already know everything.
I'm sorry also, and maybe it's just me.
I apologize to the original poster for messing this up.

Bumping an old thread... While perusing the '68 H/O production parts list, I found the attached info. The hood insulation was marked as "DELETE" for the '68 H/O.
Therefore, while the '68-69 W30/31/32 cars may have had hood insulation, a '68 H/O should not have hood insulation, based on observations from owners above and the production parts list.

My 68 H/O was the same...

Mine had "QE" in chalk behind the A/C box on the firewall.

I do have a full copy of the document I posted, somewhere. I have been looking for it, and haven't been able to find it since I moved... it's hanging out with my "442 by the numbers" book.
I got that sheet as part of the H/OCA library information packet they sell you, it's worth the money in my opinion. It also shows you the memo for engine part numbers used for the H/O engine - showing how they started with a 98 shortblock (not a Toro engine like '69), no mention of blueprinting.
As a side note, the "X 5" marking has been found on at least two more '68 H/O hood undersides... have pictures on the other computer.
