Gary Lewis Posted April 22, 2019 Share Posted April 22, 2019 Sorry for another question, ut was thinking of getting a new one barrel carter carb.... Which manufacturer or rebuild house sells the best carb? So many remans and new ones too! Also, I found an illustration of the intake assembly. Looks like it shows one of those two bolts I asked about above. Also shows a carb spacer, which I dont have. The egr valve was sitting there. Guess I need to find one of those now too. The vacuum tree at/on the thermostat housing is mainly there for emissions, not heater control, and I believe it can be eliminated. It can on the V8's, and I'm pretty sure it can on the six. The two bolts are probably the ones that tie the intake to the exhaust? On the carb, David bought a carb, if I remember correctly, from a rebuild house and has been happy with it. I'll see what I can find in his report on MPG. And the spacer is necessary if not running EGR. Or, modify the EGR plate. Jonathan and David know about those things. Let's see if they chime in before I find it via searching. Link to comment Share on other sites More sharing options...

Gary Lewis Posted April 22, 2019 Share Posted April 22, 2019 Right. Still need to find where he got it....... The thread on FTE doesn't say where he got it, just that it is a Carter YF 4901 S carburetor [from 1970 F350 with 300 engine]; choke converted to manual. Perhaps David will be on in a bit and tell us where he got it. Link to comment Share on other sites More sharing options...

What if you took three 1 barrel carbs, three stock intakes, and took the center section of the intake out and used it in three places? So, 1 barrel feeds 2 cylinders. Cap/weld the intake runners after cutting. Basically a three piece intake manifold. Would that overfeed the engine? Reduce torque? Slow velocity? Hmmmmm.......... If I am going to spend all that money on a Offenhauser, or a Clifford setup with two barrel carb and headers, or two two barrel carbs etc....why not attempt a custom three piece intake setup? Bigger cam, and exhaust upgrades would obviously be needed, but I am thinking out loud. ....continue rolling your eyes in 3...2...1.... Link to comment Share on other sites More sharing options...

I have ash, pine, cedar, locust and red oak sitting here..... Locust would probably be the toughest, and take more abuse than all the others. How tall should that spacer be? 1"?

Grafting several intakes together has been done, but there's no reason to cap between them. Connecting them gives more balance to the air/fuel ratio than keeping them separate would do. And, it lets the heat from the center one get to the other intakes for fuel atomization. As for the wooden box, you'd also need a metal plate to protect where the exhaust gases would hit the wood. But, otherwise it might work and provide heat isolation for the carb. As for height, you want it to be close to stock so the throttle cable, air cleaner, etc fit.

Mine has a solenoid that opens and closes to a line that ran to the charcoal canister. I am assuming that was a Californication special carb. These are "Autoline" remans. I've never heard of Autoline. Not sure if that is a good or bad brand. Link to comment Share on other sites More sharing options...
