Holley 5200, 250ci/c4 Maverick help?

250mav

Well-known member
so i finally got my 5200 and adapter plate. its going on my '76 250/c4 mav. so aside from that what do you guys recomend for the throttle and kick down linkage, i dont think the current setup going to work. havent even considered this yet but will i even be able to fit an air cleaner under the hood? i also want to convert the water heated choke, maybe run it of the current electric choke? if any one can post up pics and advice i'd apperciate it.
 
so ive started the 1v-2v swap today on my 250. this afternoon i took the original carb off and called it a day. i'm using an adapter plate that fits on top of the EGR plate. i was going to remove the egr plate and put the adapter directly on the intake but the bolt holes on the intake were too far apart. first question i have is which way should i mount it, im thinking putting the barrels inline with the block will give me the most even distripution as opposed to being perpendicular to the crank. It also looks like no matter how i do this theres no way i'll be able to get the original throttle cable to work but im not sure. im more than willing to keep if if possible. another issue is the down shift for the trans since it is a automatic. ive heard lokar makes a nice product to solve this problem but if anyone knows something better feel free to put it out there. the air cleaner looks like its going to be a problem as well, the carb and all fits under the hood but im not sure any aircleaner will too, might have to fab up something to sit in the scoop?

also if anyone has any after pics of a simular swap i'd love to check them out.

as always thanks for the help
 
I ran a Maverick Carter YF air cleaner on a "built" head/ 170 with a 5200 for a while. I used a BFH on the air claener which was from the YF with some finesse and it fit under the hood of a '61 Comet. Th e 250 is a little taller but it's gotta be more room than the '61...

I also used the cable linkage and pedal from the '71 Mavroc

thanks jamyers, very helpfull posts you made.

still dont know what to do about the throttle cable though. you had some type of rod linkage but the cable on a maverick is pretty identical to powerband's pic but that spring loaded end on the cable makes it imposible to bend arounf the drivers side of the carb where the throttle is. do you guys think i should also run my dizzy off the vac ports in the intake? right now the only line in there is the tranny. the ignigtion is the stock set up for a '76. if I leave the egr spacer i can run the pvc from the stock location. would a non-egr spacer still have the pvc hook up in the front? thats no biggie, looks like getting the gas pedle conected to the carb is my most pressing issue
 
I had that carb mounted on our 250.Maverick the very same way as Powerband except I redrilled & tapped the intake to make it line up. I used the stock throttle cable on the 73 Maverick and it worked fine.

I still haven't put my 5200 on yet because of some of these questions.
I have the Stovebolt adapter.
I can see the stock cable arrangement working, but the kickdown is a little more tricky.
I was considering modifying the kickdown with an extension welded on to the tip.
 
will i have to remove the spring and everything off the end of the throttle cable? i cant bend it arount to the carb with it in place. is there some way to remove all that?

Whoa...your throttle is on the driver's side??? Which way is your float bowl pointing - sounds like you may actually have a Weber/Carter DGV carb, the mirror-image model of the 5200/DFV. Got any pics?

Put another way: If you hold your carb with the float bowl pointing North, the throttle connection should be on the South side. If your throttle moves to the West to open, it's a DFV and should work fine with your throttle with a little tinkering. If your throttle moves EAST to open, it's a DGV, and you'll need a longer throttle cable to go around and hook up.

I'd think that if you've got a DFV/5200, your throttle cable oughta line right up with the float-bowl facing forward (which is the preferred way to mount them).

Got any pics of what you're looking at?

...do you guys think i should also run my dizzy off the vac ports in the intake? right now the only line in there is the tranny. the ignigtion is the stock set up for a '76. if I leave the egr spacer i can run the pvc from the stock location. would a non-egr spacer still have the pvc hook up in the front? thats no biggie, looks like getting the gas pedle conected to the carb is my most pressing issue
Unless you're keeping the EGR, I'd lose the spacer and drill/mount the adapter straight to the manifold like I did, just 'cause it's more compact and neater. I'd also run the dizzy vacuum to whatever port is nearest the base of the carb and easiest/neatest to do.
 
no no no i had a little dislexic moment there, my bad. the throttle cable conects to the carb on the passanger side of the carb. my carb is exactly the same as the one you have.
 
alright i think i see what im doing wrong.

to use the stock throttle cable i have to mount the carb like powerband did

ive been trying to do it 90* counter clockwise from whats pictured above. the way it it was in jamyers pic (below)

will i sacrifice much performance from one way or the other?

thanks for all the help
 
Since the carburetor will not be directly mounted to the intake and is funneled through a one barrel adapter I don't see any effects one way or the other as to which way the two throttle bores are turned. Just mount it with the float bowl forward so your cable will line up. It worked for me. I never got my kickdown linkage hooked. I did purchase a Lokar cable that should have worked had I ever gotten around to it.

Ain't this fun, Lots of info and some of it may even be right!.

I have a few confusions that are topic related :

I thought the Carter/Weber is a different Carb than the Holley/Weber 5200 series. and applications like Chevette (Dodge ?) used opposite - mirror linkage version is 5400(5100 ?) . The "StoveBolt" Carter / Weber I thought is smaller CFM synchronous carb.

If I remember right, the Maverick linkage I'm using was pulling from above the throttle plate on the YF it was designed for. To use the MAv, I reversed it to pull from beneath for the 5200.


The water choke is easily switched with an electric adaptor for @ $20 . I use the car iin fair weather so I didn't bother, I just set the choke at open..

The "Stovebolt" setups are geared to multiple carbs for dual and triples on big early year sixes.
