Other then the Wieand tunnel ram, is there a Holley 2x4v manifold that anyone is making for a 9.2 Cleveland?

I still have never seen the Ford "experimental" one. The 3x2v Ford, yes I've seen, but not a 2x4v.

Any info on one?

Some 351w 2x4v have been made so I suppose there is always hope but seems the Aussies are the only ones still interested in this engine at all?
Nothing in production except for the tunnel ram that I'm aware of (BTW, I have one of those of for sale). I've seen pictures of the SK part Ford 2x4 barrel intake and have a magazine article where it was tested. It made 40 HP more than the tunnel ram tested. The engine need stiffer valve springs and floated at 6600 RPM and may have made better power at higher RPM.

Offy used to make a "Power Port" Tunnel ram for the 4V C. Dunno if it is still available.

Here's a pic of Ak Miller working with it. It was purported to be an open plenum single plane and was a dog according to some limited testing by Ak. However, I suspect that intake would have required a bunch more cam than Ak was testing with. I have the article if you are interested. A pair of IR Inlines are also tested and mentioned.

I know of two 351W 2x4s. Eldelbrock and Price Motorsport, the latter requires the carbs to be run in reverse supposedly for distributor clearance but not sure I understand that. There's a chance with some work that one of these could be adapted to a 2V C, but ports and runners are too small to really suit a 4V. If you really want a 2x4 on a C that runs properly, best bet is to buy one of the Shelby or HM 2x4 Boss 302 intakes and a set of adapter plates. -Bring a pile of dough with you. They would have an unused waterneck but would be a dual plane 2x4 with proper ports and runners for a 4V C and would also have distributor clearance. -Still dont think you could run it on your Pantera with out notching your hood.

Best,

I would like to see a copy of that article and the picture of the manifold if you wouldn't mind positing it or emailing to me.

I never saw either.

Wow! Great picture! It wasn't a low riser either? Look at the height of those plenums and the angles of the ports?

Looks a lot like the 427 Tunnel wedge?

I think I'm in love...but as usual...all reved up with no where to go? LOL! Big Grin

Thanks

There was a Shelby scriprt 2x4v Holley made for the Boss 302. In all these years I have only seen one and it sold for $3,000, "back then".

It was very, very similar to the 302 Tunnelport and the 289 Trans Am manifold, with the obvious Boss 302 port differences.

I am running the Hi-rise 2x4 on my 68 Shelby with a 347. Holley 600s. This thing kicks serious booty. I would think that that 351c 2x4 would run similarly with a bigger cube Cleveland with smaller port heads?

There are Ak Miller fans and anti-fans. His tastes in induction are a little to weird for me. He probably didn't like any of the Cleveland stuff because it wouldn't adapt to a turbo charged propane engine easily if I understand his way of thinking, but that's just me? I hate everybody. LOL

That picture is all I have. Dont think more than a handful of those intakes ever saw the light of day. Here's the article. It's not the most enlightening.

Best,

thanks Kelly. I have never seen this article. I have never met anyone who as actually seen this manifold in person. They "heard" that Ford made one but never saw it. Wink

As far as the Edelbrock that takes his carbs. Those are the continuation of the Carter AFB design with his improvements and name on them. The advantage to them is that they are shorter then the Holleys.

I can tell you that the original Ford design of the 2x4 manifold had the carbs mounted backwards. They first appeared on the FE's. I think the 427 in 63was the first to get them.

By mounting them backwards there are two advantages. 1) the front carb becomes the primary carb and the primaries it are very close to being centered into the manifold 2) the set up uses the 1860 series Holley with the metering plate in the secondary. That reduces the overall length of the carb by about 1/2" and enables the carb to be centered in the manifold and have a little breathing room against the distributor cap.

The 2x4's that were built for the Carter carb design do not have that issue.

My 302 (347) has it's carbs mounted this way, i.e., backwards. Even so, the secondary carb is right up against the firewall and overhangs the back of the engine.

Since there is excellent, and some claim the best, carb linkage for this setup from the 427 Ford, the car runs around town on only the primary 2v barrels of the primary carb. The primaries in the secondaries start to open around 3500 and at a faster rate then the primary/primaries so that at full throttle they both are wide open.

You would think that the engine was drastically over carbed with this set up but I can tell you that in both cases of both my Shelbys, 68 GT350 and 67 GT500, they are not.

I have Webers on my Pantera and I have the ability to compare these things all side by side and can tell you that the small block with 2x4's is the best set up of them all.

Of course I always wanted to try the Doug Nash with the two Autolite inlines on the Pantera but couldn't put all the parts together at the same time and gave up and went back to the Webers.

You wouldn't possibly know who might have one of those set ups now would you Kelly...Kelly? Big Grin
