C2:67 Exhaust Heat Shields-Undercar

[Gerard F.]

There's a long one (13") and a short one (10")on my 67 327/300 with 2.5" exhaust.

Does the long one go on the passenger side, and the short one on the driver side? Are the screws through the straps on the left side on both shields?
Trying to reinstall my originals in accordance with the AIM after my exhaust system installer screwed them up.

Also reinstalling my original Heat Riser Valve.

Boy am I getting anal about this!

On my '66/300, both heat shields are ~13" in length, if you measure through the curve(s). Screws are on inboard side, as installed, both shields.

Well it looks like I've got mine on backwards with both sets of screws outboard.
I'll have to reset them tomorrow. You just can't trust the drawing in the 67 AIM or I'm reading it wrong.

But I do have a short one and a long one (10" & 13")and they are original to my 67. I wonder if anyone has come across this on a 67.

Having fun,

Jeff et al,
On a related matter, in your opinion do these heat shields work? My 66 is not judged and I am missing the shields. Save my money?

Randy - Aside of the judging scene, it's my opinion that the exhaust heat shields are in the same category as the ignition shielding on radio equipped Corvettes as things seem to work just as well without them and the're a PITA to deal with. Pete

Re: C2:67 There's a Long one and

a Short one, at least on a 67. Got it figured out with a little trial and error and reviewing the AIM upside down. The long one on the top goes on the drivers side with the screws inboard. The short one goes on the passenger side with the screws inboard. The screws go in vertical by the AIM.

With this arrangement, one is heat protecting the fiberglass corner of the floorboards of the passenger compartment. The corner of the floor at both the drivers side right foot and passenger side left foot come pretty close to the exhaust pipes. I guess a hotdog could melt the floorboard corner and get a hot foot. But I still can't figure why one is shorter then the other.

Here's what they look like with a little bead blasting:


Boy, did I have fun today! Saved $40.

Randy,

I doubt if they ever accomplished much. Particularly, some of the repro's are austenitic (non-magnetic) stainless which is much less efficient at sinking off heat than carbon steel originals.

Ever have a hot right pinkie toe?

On a long drive. And even with the heat shields.

67 Uh oh; The RH one is missing metal

All kidding aside. The "short" RH one you have pictured is missing a few inches of metal where it steps down in diameter and narrows. All the 2 1/2" RH side have this step down in diameter and narrowing. I have a nice set of all 63-67 version (original ones) that I used as a sales display (many years ago) to show how nice and faithful the repro was for this item. I even got the blueprints for all of them and recently displayed them a Carlisle. At least you found out now, before the Black hats sharpened their pencils.

PS Page 187 of a well know illustrated catalog shows it in the absolute right hand lower corner. There you'll see these missing metal. Often these were badly corroded.

Re: 67 Uh oh; The RH one is missing metal

Geoffrey,

I looked up page 187 of that famous catalog and the illustration of the "V" heat shields, and one does look shorter than the other in the illustration.
In fact, the heat shields in my picture look like the ones in the illustration, except for the neck down on the left side one.

I've owned this 67 for 37 years now, and this is the first time I have had the exhaust shields off for new front pipes. I believe these are the heat shields that were put on in the factory. I found that the RH side one was 10" long and looks just like the illustration in the position of the straps. The LH side was 13" long although doesn't have the neckdown and extension beyond
the strap on one side. How long do the blueprints show for a 66-67

My car was a late June 67 car, could it be that I have heat shields intended for a 68.

In any case, I'll have your catalog illustration with me when the Black Hats are sharpening their pencils.:):) (It's only 10 points anyhow)

Best Wishes,

Jerry -

Actually, the heat shields are more like ONE point.
