Blackout on mufflers

[Danny P.]

Just notice by GM photo, they really loaded the black out and heavy dripping coming down from the rear mufflers on the assembly line, See photo of rear Muffler.attachment.jpg

Re: Blackout on mufflers

I have a picture of a 65 going down the line with a great deal of black out all the way to where the down turn of the front pipe to the mufflers. I can not see the pipes is your pic. but I am sure they were the same through C2/3 era’s and maybe further. The idea was to hide those ugly mufflers and pipes from behind.

Ed, when you zoom into this photo of muffler you can really see the heavy duty dripping, some say it was a glove Mitt some say it was a heavy duty black out spray gun, so it wasn't a simple flat black spray can with a light coating .

Guys,

I am of the opinion that mid years are usually blacked out from the top side and it either dripped or got over sprayed. In regard to 70-72's I have mostly seen them blacked out on the bottom portion. I have seen what I believed at the time it was done on the assembly line and some
70-72's have been observed where the top and lower portions were received black out. I don't believe that was the norm, but its my opinion that there is nor right or wrong, or should I say typical or not typical.

Ron , they say the C2 or 67 in my case when going down the assembly line and just before the body got drop they spray the black out on a Down ward motion, I can't see the very bottom getting Black out sprayed that why the reason for heavy duty dripping down the muffler, but again who know .

Re: Blackout on mufflers

I guess I don't get it...why would you black out the TOP of a muffler or pipe?
You can't see any of that after the body is in place and the pipes and mufflers are fully installed.

Re: Blackout on mufflers

It would be hard for me to be this sloppy on a restoration.

Since this is a September '64 Motor Trend, could this be a MY 1965? I wonder how the exhaust was revised from the year before...

I don’t know maybe you can explain , heard if its true or not a pail of black out paint they had a mitt or rag and used that to black out the exhaust system from front to rear or was it sprayed on ??, here’s a 1967 427L88 front exhaust pipes looks like black out with a Mitt ?C5D3EE5B-DF84-450F-A3F3-6FAB23521E66.jpg

I total agree Patrick , good old heavy duty spray gun 👍

Re: Blackout on mufflers

No mitt! Here are a few shorts of where the mitt urban legend came from (my opinion)
Note when installing the rear end assembly it had already been "blackout" so when handling you got that appearance especially
on the 1/2 shafts.

And a example of an original 65 muffler
