1Honey my '83 F-100

[87gtVIC]

Nice truck. I find the gears on that carb/linkage very cool.

Twin Webers on a 300 six, definitely did not expect that! 38 DGASs I presume?
Gonna be cool!

DGES
A fella on another forum made me a deal I couldn't refuse on an entire Clifford performance rig.
carbs, jetting kit, intake, fuel pressure regulator, split header, and another set of gaskets.
Likely to perform better than the one barrel carb and cast iron log exhaust manifold on there.

[sly]

Yep. From what I've read, the Clifford still has a slight fuel lean on 1 and 6 and rich on 3 and 4, but nowhere near as bad as the original log. Should definitely help. I've heard they are good for boosted applications too if you ever wanted to make it a little more spicy.

[clutch47]

I read that too, and I'm thinking the dual carb likely lessens that substantially over the single 4V. We'll see.

At this time, I can't see putting it under pressure but who knows going forward. I just need it to be strong enough to pull my car trailer with a zero turn or maybe another project car or something on it, and to haul me, my coffee, and my dog to the parts store.
In thinking this through, I'm going to try to add A/C somehow..

I imagine the fuel distribution with a twin 2bbl is a little better than a single 4bbl, and anything has to be less horrible than the stock setup.

Are those a progressive 2bbl, or just a standard both holes feed fuel all the time setup?

[clutch47]

I've never screwed with Webers and they aren't here yet. Big brown truck comes Tuesday. I'd guess with the geared throttle shafts they aren't progressive but who knows.

[gadget73]

apparently the S in DGES means synchronized throttles, so standard 2bbl, and each bore is 38mm. Makes more sense given the physical layout.

have you driven it at all with the 1bbl? Curious what the seat of the pants improvement with the intake and exhaust will be. Also wondering if re-curving the distributor will help. Thinking maybe bring the advance in sooner should make it snappier.

[clutch47]

It has the original Duraspark II (I think) in there still. The box appears to be original as the screw heads haven't seen tools, so a recurve might help. There are some guys out there really deep in these inlines, and they give lots of advice and connections on fordsix.com .. my penchant for building stuff is heavily activated on there.
As far as driving it goes, it has off idle power that is really great. I mean it is really great for 6 in a row.

Up to say 1800rpm it's in a league of its own as far as half dozens go.
I've had 2 other 300-6s, both efi (a 95 4.9 5 speed and a 96 4.9 van auto) and this makes substantially more torque than they did. So at about 15 miles an hour it starts to groan.

I'm thinking these carbs and more air in/ air out potential coupled with the 3.50 rear should do me well.

[DerekTheGreat]

The last 300 I had was also EFI. Had a 3.55 limited slip and that was a great ratio for that six. Not for mileage, but definitely for seat of the pants feel.

Air in and out is also largely cam & head dependent. The linkage on those carbs looks purely mechanical, no vac. If no cam or head changes, I hate to say it, but you might be flushing a toilet on top of the engine afterwords. Isn't the stock carb something like 300cfm? If what I'm reading about those Webers and the stock carb is accurate, you'll be capable of dumping about double that with the new setup. Who knows, perhaps the intake and exhaust manifold changes allow the engine to breathe enough to want the additional fuel?

[clutch47]

Not really sure about any inline performance stuff.
My first go-round with a carb 300, and we'll see how this goes.
The jeep guys at our local off-road park LOVE these Clifford rigs.

Was finally able to do some investigating into an unknown wetness on the front of this engine.
It was antifreeze and there was no sign anywhere of a water pump leak, or any clean trails from water running so I pulled off the water neck and viola. One side of one of the ears was cracked.
Try finding another water neck for a 4.9 on a Saturday morning.
Boy.. 'Cash for clunkers' really screwed everything up.
I had 7 great yards near me that were seriously stocked.
Now, down to 2. Both 40 minutes away. Hardly worth the fuel to go get the part.

You KNOW you're going for it!

That Dorman 902-1002 or 1025 is exactly what I'm after and would be a bolt on affair.
My friend put one on their shops NAPA order today, so I'll have it Tuesday.
Cost is $18.89 and list is $33.90.
Interesting enough there is one available for leaded fuel engines that looks a bit different.
Likely for pumps generators and service engines I'm guessing.

I've been thinking about doing a totally unscientific and likely unrepeatable felt power and acceleration test of the one barrel mixer VS the pair of 2 barrel Italian sports car mixers.
Maybe downloading an app and using that in both runs. I've only got one hand that works well enough to fiddle with a phone and that'll be driving.

Feel free to recommend an app.

Fuel lines in engine compartment general question.
Opinions on steel, aluminum, push-loc PTFE hose or just plain old rubber hose and clamps.

I need to plumb from the OEM fuel pump to a regulator and then split it to two Webers.

Thinking steel from the pump to the regulator on the firewall with a rubber section for flex and movement, then from the regulator to a single brass tee in steel, then to the carbs with push-loc and PTFE.

Open to i-deers.
