Can anyone point me in the right direction on carb choices with the Offy 5205 tri-carb manifold? Better yet is anyone using this setup now on a 63 Ranchero or Falcon?Something that will provide the best performance actually allow the hood to close as well.

You can use lots of different stock type Ford 1V Carb's from the early Holley glass bowls 1904's / 1908's probally one of the very best looking set up's. As well as all the way up to the newer and bigger Carter YF's. This site has lots of pictures of most all these 3 X 1V carb systems from the first ones made in the old magazine articles and used way back in mid 1959 with the introduction of the all new 1960 Ford Falcon 144 cu. in. Six. Up to the Ford Mav GT show car with the 250 six in 1971. Many are also now using the newer Weber 34 ICT Carb's too, see below for one example of that.

In some of site member "64 200 ranchero" he has stated he uses a programmable msd ignition. a 90 HP shot of nitrous and that his engine has about a 11-1ish compression ratio with the iron head (I don't remember seeing what year head he is using. I think I remember that His engine was first in a 1964 Ranchero with a set of 3 of the Weber 34 ICT Carb's then he swaped the engine in his current 1960 Ranchero and continued to mod it so that it now has 2 Weber 34 ICT Carb's and a Weber 38/38 on the Offy Tri-Power 200. He also then added the Nitrous kit and a water meth system. If you search his posts you can see his compleate journey and all his great mod's that he's done over time.

The good thing about all the early Falcons from 1960 to 1965 with a 144, 170, or 200, Ford Small Sill they will have plenty of hood clearance were most any of the 1V Carb's will fit. As you can see in the above picture those Weber 34 ICT carbs are even shorter. Best of luck on your 1963 Ranchero build.

To the Carter YF's, this site has lots of pictures still of most all these systems from the first ones used in mid 1959 with the introduction of the new 1960 Falcon 144 cu. in. Up to the Mav GT in 1971. Many also use the Weber 34 ICT Carb's too. See below for one example.
In some of 64 200 ranchero has stated that he uses a programmable msd ignition. a 90 HP shot of nitrous and that he has found that the engine is really limited on how much the timing may advance at lower rpm due to his 11-1ish compression ratio with the iron head (I don't remember what year head he is using. He was almost able to remove all of the detonation however, the engine is sensitive to the weather and will still detonate at times, so he was thinking about going to e85. His engine was first in a 1964 Ranchero with 3 Weber 34 ict carbs then he installed the engine in his current 1960 Ranchero and continued to mod it so that it now has 2 Weber 34 ICT Carb's and a Weber 38/38 on the Offy Tri-Power 200. He also then added the Nitrous kit and a water meth system. If you search his posts you can see is compleate journey and all his great mod's that he's done.

Thank you Sir! Very much appreciated info👍 I have one Autolite 1100 now, but it’s spark scv with the old Distributor. I want to go DUI with some good carbs for the Offy 5205.

Your welcome. Lots of the Tri-Power systems have used the Autolite 1100 for the center carb and a pair of the Holley 1904's for the two end Carb's. There are also those that used three ot the 1100's too. The Autolite is one carb that can be easily modded from the SCV over to a Ported Vacuum that will work with the newer distributors. It's called the "Drop A Load" mod. Yes a C4 can work fine with the Tri-Power system too some years of C4's that will work better than others I like the 1971 up C4 transmissions they have all of the factory improvements and there are great shift kits made by TransGo to help them shift even better. If you also put a more modern cam in the engine than somtimes the torque converter may need to be modded to have a little more stall speed. Edited

Awesome! I rather go with the 1100’s since I already have one of the 3 I need. Can you refer me to a link on “drop and load” of this carb. Is it as simple as plugging the scv and the vacuum port on the carburetor and maybe drawing the vacuum from the intake?

I noticed ur thread 'label' and imagine ur well beyond this but there's an Offie prt number for earlier v later heads, just wanted to offer that anyway. Also that many here do not support the DUI choice. It's not just finances but outcome. The money's better spent on the DSII system as the hei leaks oil, has other problems (did they improve it yet?) & DSII very good. The ITCs are oe from the 1600 cc vedub, no? Room might B more precious between the center & outer carbs than the hood (I have 6 or 8 raise the hood work a rounds if needed). And direct Q = https://fordsix.com/search/8459/?q=drop+a+load&o=date
HTH. Love multi carb mods (esp all those over initial oem deign - 6 is good tho, fogedaboda Ferraris etc (=12 ... 8^0 ... ???)

If you're taking your distributor vacuum from the manifold, you don't need to modify the SCV 1100, as it no longer matters what kind of vacuum signal it is generating. Just cap the vacuum port on the side of the carb to prevent a leak.

Thank you for the info👍 The 5205 is for small log 144,170 and 200 small log from 63-68. I agree with you on the DUI after being educated on the dizzy swaps by a very reliable source👍 I’m going DSII. So appreciate your response!

I would still modify the carb. in case you want to try ported vacuum. All depends on the his cam choice.
I recommended call Jerry at Schneider Cams. He is very knowledgeable with the small Ford Six.
