Hot Rods Carbs on a inliner

I have an old Clifford 3x2 intake with 3 2bbl. holleys that are 2300 model. What do I need to do so I can run this on the street, or is this two much. the engine is a stock 292ci. or am I just dreaming.

 

Put it on the engine and adjust from there. May need to rejet, use progressive linkage or block one or two off. Gotta try it ..........

 

You may find the power valves very diffacult to get right. I blocked mine off. Went up 8 or 10 sizes on the main jet. Wasn't looking for milage

 

Thanks Guys, can't block one off each carb runs two cylinders. but I will try to get it running and maybe try jetting. I as well not looking for milage.

 

Bravo, A 292!
Those progressive deuces from WEBER might be worth a look.

 

I can't find any reference to a 3 × 2 Clifford for a 292 - is it marked "Clifford"?
Pictures?

That area between the Main runners is not a balance tube is it? It is just a casting to hold the runners together. More like the old man-a-fre,Not like the old Dos Palmos triple 2b Where it had a balance tube between the runner.Or like my 3x4 tunnle ram where it has a plenum to act as a balance tube.But the carbs still sit right over each runner.I'd say go ahead and start with the stock jetting and work your way down till the motor is happy.

 

If it's really separated (or only a 1/4" hole for balance between pairs of ports) it's much easier to set up.
The jetting will be identical for all (duh) including float height, degrees of throttle blade angle at idle, etc. If possible, use a Uni-Syn etc. to set the throttle arms.
The only hard part is finding the vacuum size for the power valves.
The usual methods require finding the engine vacuum at idle or cruise (whichever is lower), and subtracting between 2-5".
Example: 50 MPH shows 12" vacuum - you can use 10" down to 7".
Which is best? You don't want the PV to open unless it's needed to save the engine from bogging when you roll the throttle on.
If it comes on too soon (10") you'll be in it on every hill, and the mileage suffers.
If it comes on too late (7") you'll have a flat spot in between 7 and 9 or so where moving the pedal doesn't do much.
If you disable/remove the PVs expect the following:
1. black plugs
2. 5 mpg
3. change oil once a week

 

What Twisted 6 alluded to - on the street you are going to need a balance tube so all cylinders communicate to each carb. Use 350 cfm or SMALLER carbs. Don't even think about three 500s on the street.

 

The balance need not be anything elaborate. Just drill and tap the manifold at each carb to 1/4-27 NPT, install a piece to hose nipple, and run 3/8" hose between them. Better top run it above than below the carbs so fuel doesn't pool. Do not run a big line - kills response.
If you're serious about balancing them a hose is also easier to remove from the equation - either substitute short stubs with a cork in it, or just pinch the hose shut.

 

Regarding size: remember, if the manifold is constructed as you say (3 groups of 2 cylinders, no common plenum) each carb is not supplying the engine, nor can the engine draw from all three carbs no matter what linkage you use.
Each carb only feeds a 97" 2 cylinder motor, 350 each should work.

 

Got a picture of that manifold?

 

Yea its a Clifford, they don't make them anymore.
Sorry , No pics at this time there at work and I'm off for a week.
Thanks to all this is excellent info.
When I get back to work I will post up some pics.

 

does it look like this?

That is Engine companys Intake and it is also heated.And not even close to the Old Clifford

 

If any of you guys has the Leo Santucci book Power Manual there's a pic on page116 at the bottom left corner
