Heat Shield on RA Manifold?
1 Attachment(s)
On my 1970 GTO driver's side log manifold, there was a heat shield with riser tube to the air cleaner (see pic).
I purchased RARE oversized manifolds to replace the stock logs. Do ram air manifolds use a shield? If so, does someone make one that fits or will the stock one work? Also...how necessary? https://forums.maxperformanceinc.com...1&d=1623291509 |
I think I found my answer...from OPGI. Of course, backordered until August.
Heat Shroud, 1968-70 GTO Ram Air, D-Port https://www.opgi.com/product/image/O...rt-g201173.jpg *Edit...looks like Ames has it too. |
Barry makes those for everyone. Call him.

Apologies...Barry who?
I guess the main question is the necessity of using this on the new motor with the new RARE manifolds. Obviously wouldn't be used if I had went the header route. Would also mean backing out the 2 ARP bolts already installed for mounting (and if anytime I wanted/needed to get at the manifolds). How many of the guys using the RARE manifolds opted to buy/install these? I am assuming the only purpose is to preheat air and route to the air cleaner for emissions purposes? No perceived performance or functionality gain? |

"" Heat Shroud, 1968-70 GTO Ram Air, D-Port""
another misled quote by the repoppers 68 HO yes,, 68 ram air no .... and they fit OVER the head bolt on the threaded stud and held on with a locking castle nut |
This would be on a '70 with the oversized RARE (2.5") reproductions.
Any issue with fitment on those? |
those manifolds are only oversized in the ID;
IIRC they have a bit more meat at the pipe connector too - otherwise they are dimensionally identical to originals. |
Sorry link didnt work . Barry's business is Sonic Motors. Check his e-bay store there is one listed or google and call him.

I have them on my 72 HO motor with RARE manifolds. They fit the manifolds fine. I don't let the hot air get to my air cleaner though. I put them on because I want to motor to look stock on the outside.

Pick one up at the natz in Ohio in august. Barry’s usually there.
