Aluminum heat shield?
What years used the aluminum flat heat shield between carb and intake manifold? Where they used on both 2 BBL and 4BBL small blocks and or big blocks?

Re: Aluminum heat shield?
I've never seen a carb heat shield stock on a 67-72 truck. It would think it would only be used on Holley equipped engines since the Holleys have fuel bowls that hang over the intake. Maybe you are thinking of an aluminum carb spacer that fits under just the carb base plate?

Re: Aluminum heat shield?
Shield has firing order and GM part # 3973231. Was off a 70 or 71 350 pickup.Or maybe it was a corvette engine?

Z28 from 67-69 had them. Similar ones available at your local speed shop. Easy to make one too.

Re: Aluminum heat shield?

Re: Aluminum heat shield?
I bought a '70 GMC a few years ago that had one on it. I have no idea if it came that way, but it appeared original under the hood.

Re: Aluminum heat shield?
The plot thickens. Here one used on a 100pt restoration out of the Brothers catalog. Still, the years used is a mystery.Its possible many original shields may have been discarded after a carb change.

Re: Aluminum heat shield?
My 70 burb has one under the 2 bbl on the original 307. Mine was a California truck and it also has some extra evaporative hoses that my 70 from New York doesn't have.. Maybe the shields were put only on California vehicles? I do know that there were specific Q jets for the California vehicles.

Re: Aluminum heat shield?
I just happened to be in California and Brothers truck parts is in California. Special equipment for California's tougher emission laws vs. the other 49 states sounds right, thankyou rsavage.
