No kickdown linkage needed with manual trans. There's likely enough used manifolds out there for an FE that you shouldn't have to buy new. Edelbrock, Weiand, Holley, Offenhauser all offered a nice dual plane street manifold for the FE. The AFB Edelbrock carbs would probably work just fine, in 600 cfm, (1406?), though I do prefer Holley style carbs. I'd look into getting a carb from Riley's Rebuilds if I was looking to get an AFB. Put a nice mild hyd cam in it, and time it with cam advanced, it will run like gang busters. The 4.11 might not be a bad thing since this is a 250 with 16" tires. I've forgotten more about FE's than I remember lol! Still have one in my 67 Mustang!

Get whatever carb you want. Lots of choice there but stick to vacuum secondary for your application!!!!

Suppose a guy found a like-new Offenhauser for slightly less than the price of a new Edelbrock. Both dual plane aluminum intakes. Is there an advantage to one over the other? Or with the Offenhauser are you just paying for a name?

I have never used Offenhauser intake but have certainly heard lots about them.  I would go for it. Vintage on vintage. Makes for great stories in the shop. Smile

Could someone tell me what the tube coming out of the right front of the manifold is for? None of the new ones I’ve seen have that. At first I thought an oil fill tube but since I haven’t had my manifold off yet, I don’t know where it would lead to if that’s the case.
Also, why is there a notch machined out of the divider between the plenums?
Last question…there is a hole at the back end of manifold with two bolt holes. No other FE manifold I’ve seen has had that hole. Looks like where the thermostat housing would go on a GM. Since GM has the distributor at the opposite end of the thermostat, could it be possible this isn’t an FE intake?

Most definitely an FE intake. I have the dual quad version of that. I made a block off plate for the rear opening as the oil fill is in the valve cover. Mine does not have the tube in front

Does it still have the thermostat location on the front?
I’m just wondering if that’s some kind of marine setup?

Yes thermostat is in the front facing forward with an L shaped housing. In photos I've seen the tube is the oil fill. My cast iron manifold for the 68 does not have this fill tube. The Offy dual quad I have has the opening for a fill tube but I don't have the tube. The big opening in the back opens directly to the lifter valley. I don't know what would go there and I can't find literature that shows it. That's why I made the block off plate

Creston, is that a 'dual port' manifold? They had a divider in the runners. I believe the thinking was to keep the velocity high. Kind of unique. That would make a good intake for what you're doing. Ford buddy of mine growing up had one on a 429 C.J. He also had a 427 tunnel port that I drooled on a time or two. He still has the 429, it's in a '70 Torino Cobra. The tunnel port is long since gone.

rear opening is for earlier FE engines, that used a road draft tube for crankcase ventilation. They also used the tube oil fill in front like pictured. The tube can be removed and a plug installed, and a block off plate put on the rear opening. The FE went through a lot of minor changes in it's multi decade run.

Those Dual Port 360 manifolds were supposedly the thing for fuel economy for light driving and still give flow when you stomp on it. They came out after the Arab oil embargos of the late 70s early 80s. The small ports were for the primary barrels. I put one on my 75 P/U with a Thermoquad on it.
If it was fun to pull in LOW gear, I could have a John Deere.
If you can't make it GO... make it SHINY
