Will a '69 thru'72 4bbl intake work on a '74 360?
Or better yet, what 4bbl intake would work on a '74?
2bbl with a motorcraft carb. is on it now.Would like to put a 4 bbl on it.
I can get a factory cast iron intake for 100 bucks.Then I will have to find a carb for it.Thanks for the help.

 

The year doesn't matter. Any year will bolt up to your 74. It's possible to have a port mismatch depending on the head/intake combo though. What is the casting number on the intake in question? Does it have a large "S" or "T" after the casting number? Either of those would work fine. 100 bucks is kind of steep for a run of the mill cast iron 4bbl.

 

search local craigslist ,i picked up a used edelbrock performer for $80
also recently bought two holleys off craigslist
a 750 center float and a 600 side float
$50.00 for the pair ! already rebuilt the 750 and installed on my 390

 

I was thinking the same thing. I see them on CL for $25 regularly.
About the only fitment problem would be if you got into the high riser/tunnel port manifolds. I doubt you'll run into either of those but if you do, for a $100 grab it.

 

There is no such thing as a 1971/72 FE 4V intake manifold.

After 1970, the only Passenger Cars available with an FE were 1971 Ford Galaxie/LTD's. Only the 390 2V was available. No FE's after 1971.

All 1965/73 FE F100/350's came with 2V's. 1974/76, Ford offered a 390 4V as an option.

Most peeps swap 1965/68 FE manifolds from the cars, as they are plentiful and usually cheap.

 

$100 is rather steep for a cast iron intake, unless they are selling it by the pound.....

I scored a like new Performer and new in box headers for $120, so deals can be found. CL and a bit of patience can really pay off.

On the other hand, $100 for a factory aluminum intake would be a decent deal....

 

LOL RW, yeah if you find a PI, medium riser, tripower, etc. for $100 by all means scoop it up! That would be a great deal!

Most of the standard cast iron pieces can be had for free to maybe $75 tops and most of the ones worth that are only because they are the right date code for a restorer.

 

I have a 4v intake setting in my garage right now with a date code of D3. I mention it on another thread on here and a guy told me there was a M-code 4v 390 up until 76. I thought that was weird but it wasn't too important to me at the time so I did pry for any more info

I was under the impression that what you had stated, Number, was true. All evidence I've seen and literature I've ever read said that the last car FE was a 71 2v model and the truck never got a 4v. I took that for true but, as plain as day, I do have this 4v intake and it is a 73 model. I'm thinking maybe an industrial or commercial application? What do you think?

To the OP, the OEM cast manifolds are a dime a dozen. Hell, I have 3 of them setting on a shelf myself. I think the only ones out there with any value are the 390GT or the CJs and they only get a few bucks more and only from collectors that are restoring a car. They don't perform any better or worse than any other iron intake. You should be able to find something easy and cheap. I think the earlier heads had higher ports than the later models. I know the made a change to the exhaust ports around 66-67 and I think they made a change to the intakes ports too. Someone correct me if I'm wrong. If that's the case just find a later manifold. There're plenty out there so be picky.

Oh yeah if you find a PI, medium riser, tripower, etc. for $100 pick them up and let me know. I'll trade you one of my cast irom intakes for it

 

Actually the CJ intake performs virtually identically to the PI. Not too shabby. Definitely better than the rest of the iron heap. .

 

VIN engine code M = 1974/76 F100/350 390 4V.

D3 is a partial casting number prefix (foundry mark). After the manifold is cast, it is placed outside to season, then is shipped to an engine assembly plant to be finished, then installed on an engine.

Then the complete engine is shipped to an assembly plant where it is "banked" until required.

How long does all this this jazz take? Could be two months, could be much longer when you take into account the first Arab Oil Embargo that occurred late 1973. early 1974.

Did'ja ever had to wait in looong gas lines, just to be able to buy a few measily gallons of gasoline?

For the first time since WWII, peeps were concerned about MPG, so econoboxes sold like hot cakes, while gas hogs sat on dealers new vehicle storage lots.

And, snce new vehicle introduction time historically begins in September of the previous year, new vehicle production begins in August...in this case, August 1973.

So, it's very possible to have previous year date codes on parts that were not installed until the next new vehicle model run.

 

$100 does seem a little steep for an iron maiden. But sometimes it is false economy to get a manifold for cheap that is cracked or doesn't fit or has to get the pipe threads repaired. This usually happens on aluminum intakes. In any event I would bring a straight edge and a few pipe thread nipples to see what you're getting.

How about this one? 3 Two Barrel Carb for 390 or 406 Ford It's been for sale for some time. Pretty pricey. Maybe that is an indication of the rarity, or an overly optimistic seller.

Had one and used it on both 390's and a 428CJ's. Marvelous all around performer. Rated at 860 CFM on a 390 and 940 CFM on the 406 and on the street and strip. Yes, it will bolt to any 390. Oh with it on the 428CJ in my street car you could actually bounce the front tire off the ground by punching the throttle on then off and on again and that was with street tires. In the modded 428CJ in the race car it would carry the front tires better than a car length with the fender well fitting slicks.

However the craigslist one seems to be missing a bunch of throttle linkage parts.

 

Pardon my ignorance, but are you saying that the engine size will change the CFM rating on a carb setup?

 

I'm saying that's what Ford says. Those numbers are what Ford claims, right out of their "Muscle Parts Book". But if you think about it a bigger engine will suck more air than a smaller engine at the same RPM. The CFM ratings are just a standardization for comparisons. Oh and the 3 X 2 setup for both engines are identical, intake and carbs.
