It's done new Aussie 4v converison with Holley 600 CFM 4V

[Mustangaroo]

Well it's done the hack job to the old Aussie 2v intake is done. I cut the top out myself then cut a one inch Holley 4V spacer down to about 1/2 inch, then I had a local shop weld the two together from the inside (no exposed weld marks ) and had them weld up the water ports, then they applied their ceramic chrome coating and polished the intake. Then I mounted my new Holley 4160 4V, electric choke, vacuum secondary, which also is a polished zinc finish. I need to do a few things to the engine bay before installing this setup later this week, I'll post the finished pictures when done!

that is a thing of beauty. Can't wait for the complete setup and how it runs.

WOW!!!

Nice job Ben!!!

HOpefully Al will be finishing up my 4V conversion soon.

But, why not mount it the other direction (sideways, that way your primaries are parallel to the engine, for more even distribution. RIght now, with that direction, won't your front cylinders be running richer then the rear ones?

But, it looks awesome, I can't wait to try mine with my new 390 4V.

it's all about the float levels... they were designed to be mounted with the choke horn forward, move it any other way and you run into problems like those who use the clifford adapter for the h/w 5200

Yes you could mount it the other way, my son's is mounted the other way with the primaries facing the intakes, but then the primaries are closer to the #3 & #4 cylinder than the #1 & #6 cylinders, also you better have enough clearence, my 1968 Mustang shock towers don't allow as much room as the 1965 Mustang of my son's. The front facing primaries are only about I inch off center from my 2V setup I have now, yes it may run somewhat richer to the front three cylinders but I think not enough and beside I'll have all four barrells open most the time! And the biggest factor is the sideways mounted 4v looks strange.

You also have to use a bridge over your valve cover for a side style throttle cable and linkage! Believe me I have given this much thought, we will check the plugs and have it dyno-jeted when all the tuning is done and see what the results really are!
P.S. that's a Holley Quadrojet 650 CFM 4V on my son's 200 I6, and is NOT a vacuum operated secondary and is only running a ISKY 256 cam yes it did take a while to tame the 4v into running smoothly on an Auussie 250 2V head, but it can be done without much effort if you know how to tune a Holley carb.

What about using center hung floats?

Ben, I'll be interested to see the results. It probably doesn't matter which way you turn it in all reality.

I don't think it will make much, if any, difference in fuel distribution. The center opening will act like a plenum and the fuel should go pretty much the way it did before.

Very nice work, Roo....

dont think the base 4160s come with those, forgot to mention about the jets also, if people were having troubles with the 5200 jets going around corners when it wasn't orientated front forward, then maybe the same problem would come up with the 4 barrel

The Holley 3310 (750 vac-secondary) comes with center hung bowls, and it's a 4160 (has metering plate in rear, not metering block).. You can put the center hung bowls on the 1850 (600 vac sec) or any those style Holley carbs (just about all of the 'modular' design ones, except for those quadrajets replacement ones, the accel pump shooter hole is in a different location in the metering block/fuel bowl)

I put center hung bowls on my friends 1850 (on a '64 Comet w/ a 289), we got brand new chrome Holley ones from Summit, I'm not sure if they just sell the regular fuel bowls as a replacement part or not.

I don't really think the side hung bowls would be affected too much the way 'Roo has his mounted, it's facing the same way a v8 carb would... I have a 1850 on my 302 in my Stang, and I've taken some freeway off/on ramps pretty fast and it's never cut out or stalled or anything...

nice table........um i mean intake

dude that intake is aaaaaaaaaaaaaawsome arty:

 

[Anonymous]

Have any of you tried it with a two barrel 2v and then gone to the 4 bbl as the only change you made and then compaired the difference in performance.
Did you notice improvement.

 

[CobraSix]

Tim, I can do it if I want. I have a 2-4v adaptor...I can flip it, and try it, but I can't imagine it being worse...4 smaller venturies is better then 2 larger ones usually.

I agree but for all the talk on these modifications to 2V manifold I havent heard many (or anyone) talk about the difference they have felt the modification had made (ie driving).

Don't hold back on us Tim, heck you live where those 2v heads grow on trees compared to here in the USA, go pick one and post a report for us that way I wouldn't be doing one myself to find out!
No really as my earlier post says I'll post the results, I have ran a Holley 5200, Holley 2300 374 cfm (500) and soon the Holley 4v all on a stock block 200, stock cam. SO I think you may like to hear these results, but I won't have the new intake and carb on untill the end of the week, add a few tuning days and another week ot two to have a dyno-jet date to report the numbers! 8)
