Good find | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | One was used on the early Blue Flame Six 235ci Corvette. Maybe someone will check the casting code? | | | | | Joined: Jul 2010 Posts: 592 Shop Shark | | Shop Shark Joined: Jul 2010 Posts: 592 | You just found about a $1500 exhaust manifold! Jackpot!
As Tim said, they were used on the '53-'54 Corvettes, but many more were sold as accessories by the dealers because they were a bolt-on for any 235 or 261. Dealer retail price back in the day? $15!!! I have read that the majority of the production was sold as dealer accessories. If we had to rely on ones that came with Corvettes, they would be even more rare. Notice how the manifold allows for the use of the heat exchanger with a stock intake manifold.
You would have hit the Power Ball if it was attached to three carb Corvette intake.

Post a picture of the number... Mike B  | | | | | Joined: Jan 2001 Posts: 12 New Guy | | New Guy Joined: Jan 2001 Posts: 12 | I might have misinterpreted the numbers, but I most certainly did *not* "mistype" anything  Casting Number As you can see, the numbers are sufficiently degraded to where the zeros and the sixes are indistinguishable. It could very well be "3836108." To wit, I will accept "3836108" as the correct interpretation of the casting number depicted in the image. Thanks for the proper reference.

PM me with directions. I can head out in an hour from now.

The only advantage to having that one or one like it is the casting number. Even a home-brewed split manifold beats the Fenton dual setup without a heat riser.
