1966 Muffler Black Out

Re: 1966 Muffler Black Out

Well, I still think that with most judges on a '66, if the pipes and mufflers are clean without a hint of blackout anywhere, you will get a deduction. Maybe not much, but the many pictures and much documentation of the process is impossible to deny.

agreed. NTFP, eh?

Muffler Black out for a 1963 Corvette. A long time ago I bought an original Ford document where the Ford Testing Operations Office Engineering Staff bought a brand new 1963 Corvette coupe with a Powerglide to do basic engineering tests at the Dearborn Proving Ground. Attached is a picture of the rear underneath of the Corvette they tested. Thanks, Mike

If there is zero blackout on the 65 or 66 mufflers, you'll get a 1 point deduct for Finish (CDCIF).

Re: 1966 Muffler Black Out

Well, first of all... very cool source! Second, how did they get under this car without having the suspension droop? Looks like lift arms in front of the tires, but might there also be thick clear "glass" of some sort - accounting for the odd reflections in the lower left and right edges and what may be a contact patch on the tires?

What is the snaking cable that appears to goes through the diff mount?

Oh and to the black-out paint: why did GM even bother? The bulk of it would go unseen behind the lower quarter panels; hardly any on the lower rear before they get to the rear filler panel.

Re: 1966 Muffler Black Out

Exhaust Pic.jpgSuper interesting dialog here. I'm wondering the same thing with a '63. In the 7th Edition of the 1963-1964 NCRS Technical Information Manual and Judging Guide Section 12 (pg. 202) it states "A preservation-black paint was applied to the exhaust system after its installation on the chassis but prior to the body drop. The preservation paint was applied from above the chassis with a mitt/mop. Moderate to even heavy paint application was common with paint coverage on the top and sides of the pipe was good, but coverage on the bottom sides proof (as viewed from underneath)."

In my mind I'm visualizing a deck-stain like mitt on someone's hand smearing something like high-heat stove paint from the top side in a freakish motion. Not to be crude but is that what I am reading here? Looking to have my car judged and have a new exhaust on it. Looking for clarity to avoid losing points over what seems to be a confusing issue at best.

Any final guidance to put this one to bed would be great!

Re: 1966 Muffler Black Out

I hate to be pessimistic, but I don’t think there ever will be clarity on the subject. I thought the idea of mitting was dead and buried, but it keeps being resurrected.

Agreed. No mitt.
if that’s in the newest JG it’s yet one more error in there.

Re: 1966 Muffler Black Out

Understood but if the JG states it that way, do you agree that I need to paint the exhaust to avoid taking point deductions?

My suggestion...stick with the prevailing view on this. The "mitt/mop" statement on the method of application was omitted in the draft but, probably due to a lack of quality control, was printed in the final version. The intent was to avoid specifying the method and leave it that a "preservation-black paint was applied from above the chassis..."

Deal, thanks everyone!

Re: 1966 Muffler Black Out

Gary,

There seems to be enough confusion and conflicting evidence around this issue that I agree. Seems like an easy one to resolve and with an update to the current JG.
