OK...SO I'm building a '56 F100 street-rod-style-truck...local shows & for me & my girl to do a little good ol' kick a$$ street-roddin'-n-rum-runnin'...

NOW...I drove it home with a 1970 302& C4 combo & I'm preppin' a 9" rear for
right now...

I've got a TCI MII hub-to-hub IFS ready to install & gettin' ready to pull the
motor & transmission to get workin' on the chassis...

The rear suspension will be a 4-bar either triangulated or parallel...haven't
decided yet but leanin' towards the triangulated setup...I know panhard bars have been around a long time...but...panhard bars HAVE BEEN AROUND A LONG TIME!

The 302 will use either reworked OEM cast iron 302 heads---OR---351-W
heads...The rest of the of the motor will be hydraulic flat tappet cam, "some" roller goodies, roller rockers, creamic or some-sort of heat-coated-long-tube
headers, 2 1/4 exhaust piping...either NASCAR exits thru thru thr runnin' boards or all the way out past the rollpan...

Some bowl work & smooth out the edges...nothing too extreme...I really don't think I'll wind this pony up past 5500 R's...

NO $ for aluminum heads here...won't need 'em...

I was wondering which of these intake you think might might work best for my truck.

With this setup..I'm only lookin' at about 3150 lbs. without my skinny 180 lb.
butt in it it!

I was wondering which of these intake you think might might work best for my truck. 302 1-PEICE---Or----351W 2-PEICE?

However...PLAN_B MIGHT be choose between 2 OR 3 Autolite 1100's...plant this CAD designed & CFD flowed piece ON TOP of an
Air-Gap intake that way I get my idle-5500 performence along with a little nostalgia-WOW...

Remember it's a 1956 truck...just top off the Autolite 1100 carb's with some period perfect stacks...ready to GO-N-SHOW...

NOT plannin' takin' it to the track...just a kool-kruzin'-road-rippin' hot-rod...

As time & $$$ permit I would like to upgrade to an AOD transmission.

THANKX...

 

Go with the triple 2bbl intake in the 2nd pic, with the other one you would be able to look under the 3 carb manifold and see the regular one, which I think would look goofy. plus with the triple carbs you get more even fuel/air distribution to the cylinders for more power and gas milage.

 

A 600 Edelbrock with a Edelbrock Performer RPM intake would be my choice.

You must use a 302 intake. A 351W intake will be too wide since the 302 block has a 8.2" deck and a 351W is 9.5". This would make a 351W intake much wider.

 

I also like the second intake. It's posed in front of a Ford promotional sign, is it a Ford piece? I see it has the rear hole for the old "stink tube" or early PCV plumbing.

 

Both are repops...

 

I'm running one of those Vintage Speed 2x2 adapters with 2- Holley 94s on my 302 and I love it. Looks great and runs suprisingly well despite the warnings I got from others. See my website for pictures. I'm about to upgrade to a 351W and considering going to a 3x2 adapter like the first one you show.

 

If you have experience setting up multiple carbs, then the second picture is what I would choose. For the truck you are building, I wouldn't even DREAM of using the first picture item.

Multiple carbs on a fifties or sixties hot rod have great visual appeal and if you know what you're doing with them, you can make it run great.

 

DiagMan...back in the day (SO-over-used-term) I helped a buddy

straighten out a 440 six-pac set-up on a Roadrunner...

IF ya kept yer foot out of it for "regular" type drivin' things were

great...but when it came time to rock-n-roll...be affraid...be very affraid ...

Oh...That first set-up...is an adapter plate to fit 351-W heads...thought I

might get a little added performance out of 'em...but yer right...looks like

something my dog left in the yard...don't think I could find an air-cleaner BIG

enough ta hide that...

 

My 6bbl 440 that was in my 69 RoadRunner was a beast. I jetted the carbs once and drove it for years without touching them again.
It got 14mpg driving normal with a 4-speed and 3.91 gears.
Open all 3 and it ran like a scalded dog and got about 4mpg.
I had mechanical secondaries on mine. The outboards had 50cc accelerator pumps.
350cfm center carb and a pair of 500cfm carbs on either end.
I traded with a friend of mine who had an original 71 440 6bbl RoadRunner who wanted the original style carbs on his.

If you have good carbs, you will only need to set them up one time.
So if you want multiple carbs, I like 3x3's myself

The most important ingredient in setting up multiple carbs, even more important than carb savvy, is PATIENCE. If you are not patient and willing to spend the time to get it all right, you will never get there.

There are so many good car innovations that get a bad reputation because of technician ignorance. I could make a LOOOOOoooooonnngg list of examples, but here's a short one:

57 Chevy Rochester FI. Dealer techs didn't understand them so they recommended a four barrel.

Multiple carburetor systems on all makes and models. Many people don't have the patience or the carb theory knowledge so they take em off and put on a four barrel.

Here's one that is MUCH more simple with a few wires, a switch and a coil, but the technicians found one wire, one switch and one coil to be too complicated, so they condemned it as no good. This was the Doug Nash 4+3 overdrive in the late eighties Vettes. I have one and have repaired it several times and it's as simple as a light switch and a bulb, but the techs couldn't deal with it.

In the first ten years of EFI, the same thing was happening in the shops. The same thing still happens with hobbyists. EFI IMHO is probably the greatest improvement to the internal combustion engine EVER! It amazes me how many people I see on discussion forums of all brands that rip it off and put an antiquated carburetor in it's place. For all out racing, this makes horsepower sense in some cases, but it is usually due to lack of knowledge or resistance to change.

So Rockher-man put on those three deuces, make it run right and thumb your nose at the naysayers.

 

...now thats what I call a vote of confidence...I NOT against EFI by any

means...I think the new plug-n-play systems are the catz-a$$...but a little

pricey...adapting one to work is a viable option also...it's just that right

now...as things sit...I got 2 302's in the garage!!!

There is the '70(or '71) 2-bbl truck motor & C-4 already INSTALLED in the '56

F100 that we drove it home with...and in the corner of the garage on a stand is a

4-bbl 302-HO (dressed-minus pan) from a 1983 Mustang-GT 4-Speed car

that is long-gone...and I HATE Holley carb's...

I even have a '66 Autolite 4100 on the bench as a back-up "just in case...

 

Yes the old Ford carbs were indeed very good, but the Holley's are good as well. If you don't like Holleys though, then you might not like the three two's you are looking at. I don't know what you would use for Carbs on that setup other than Holley's.

 

NO holleys here...3 of THESE ponies would be THE hook-up...


Autolite 2100

A Ford in a Ford...

 

The 4180 Holley on the 83 HO is best turned into recycled aluminum. They were a good emissions carb, but not the best for performance. My ex girlfriend years ago had a 85 GT. I finally put a 4160 600cfm on it and it ran much better and trouble free.

 

Yea...that "extra" motor was left behind when my girls ex was booted...so it

just sits in the corner doing nothin'...every once in a while I go out in the

garage & throw somethin' at it...
