2V carb conversion for 200CI

[Anonymous]

Hi Folks,

looking for the simplest approach to the 2V upgrade on my 200CI. I have the performance handbook by Dave and Dennis' and now are looking to hear from people who have successfully completed the upgrade. Not looking to burn rubber just want to get good daily driver performance out of my 65 Ranchero.

The motor is rebuilt and we installed headers with dual exhaust (6-2) backed by Flow Master mufflers. All else is stock. The car sounds great and runs good but has the power of a 87 Yugo.

Not looking to cut corners and would prefer buying a new carb vs taking my chances with a rebuild.

2V carb upgrade vs large 1V?
Clifford vs Stovebolt?

Any ideas?

Thanks Guys!!

Many variations of equipment and technique for a 2bbl conversion are being worked on by members of the FSP group. One of the simplest and most drivable options is the progressive 2bbl sold as the Weber DFV-32/36 or the same carb licensed to Holley, the Holley 5200. Other solutions are the 350 and 500 Holley's (non-progressive 2bbl's) which are usually for the more performance and modified applications

I have a small pictorial of the H/W 32/36 conversion, jetting and tuning I am working on :

THis should give a good idea of the basic work involved. It was very easy to install the 'Langdon's Stovebolt' supplied 2bbl adapter and the H/W carb. The real work is the details of tuning/jetting, linkage, air cleaner and fuel supply which I am still finesse-ing.

Howdy Back Dave:

1st, a few more questions- Is your current set up stock? Autolite 1100 one barrel with a SCV? Is your distributor stock? The vacuum advance only, Load-a-matic?

If you have a stock Load-a-matic distributor, the simplist answer would be for you to find an 1101 Autolite from a 1963 and later Ford full size car or truck with a 223 six. It will have a SCV and be compatible with your OEM distributor. Your gas line, linkage and air cleaner are a direct swap. THe carb will most likely be a manual choke, so you'd have to hook up the cable.

This is a good way to go-- Only if you don't plan to upgrade your stock distributor to a later on with centrifugal advance built in and a ported vacuum advance system.

The only adaptation is that the 1101 butterfly is larger than your stock 1.5" carb hole. You will have to flair the top of the hole for clearance.

Your stock 1100 carb is rated at 185 cfm. The 1101 is rated at 210 cfm.

That should bet you thinkin'.

Adios, David

RancheroDave,

Your question is "what is the easiest way?" - so adapting a larger 1 - bbl is definitely the easiest way.

As David (CZLN6) says, there are a variety of larger 1 bbls to choose from if you have an idea of where to look.

If you would like to try a 2 bbl, the easiest 2 bbl option is an adapter such as the one Clifford Performance sells. With adapters, you will have to be careful that you do not run out of hood clearance as the adapter does raise the carb quite a bit higher.

One very popular method is the direct mount, and this requires that you remove the cylinder head and have a machine shop cut an oval shape into your intake log manifold, than an adapter needs to be mounted to the intake for the carb to mount onto.

Good luck!

Dave, I would follow the plan David has described.
First your old cylinder head is not the best head to mount a 2 barrel to, the ports are very small along with the valve size.

Unless you plan to put a later head on the engine & totally revamp your intake just stick with the 1 barrel carb mod.

Unless you plan to put a larger camshaft & a 68 up distributor in with about $1500.00 in improvements along the line, just add the carb.

The alternitive would be to turbocharge it, nothing like more air.

But to do that would require a completely different induction system, not practical in your situation. William
