Helping a friend identify. Notice the funny angle to meet the head. Also appears to be for a cross flow head. No p***age way for exhaust to go between intake runners. What is it?
The port arrangement is similar to the 258 AMC straight 6, but the angle and the bolt locations are wrong. The fact that there are webs between the ports, and the angle, suggests it's for a cross flow head. The fact that it's for 3 one barrels indicates that it's OLD. good luck
Not enough angle for a slant 6. Also the exhaust is on the other side of the cylinder head. The manifold in the background looks to be a an old MOPAR product by the flange? Painted like is was on an old truck; I like the freeze plugs under the carb flanges.
I’m thinking some kind of flathead 6, most “modern” inline 6’s clamp the intake and exhaust to the head using the same hardware for both.
My guess it's for a flathead with some sort of aftermarket head on it, maybe a 'F' head conversion. Or did anyone make a F head six?
flathead inline engines always have the intake and exhaust ports next to each other, so we know it's not for a flathead, since there's no room for the exhaust manifold, or even for exhaust ports.
Very interesting mystery manifold. The underside of the center runner looks like it had a casting tag on it, I'd like to see a closeup of the underside of that center runner. I can make it out in the second pic. Also, are the round spots directly below (what we are ***uming are) carb flanges open? Like, could you stick your finger through there? If they're open, that makes me think they would connect to another mirror image intake with pipes, like some kind of wild V12 or something. I have no idea, but I do want to know this one.
