Cleveland engine trivia quiz

George PGeorge PAdmin.
Below is a picture of two different 4 barrel carburetor Cleveland intake manifolds.

One is cast in aluminum, and is designed for the spread bore Autolite 4300D carburetor.

The other is cast in iron, and is designed for the "square bore" Autolite 4300A or Holley carburetors.

The second picture reveals the size of the runners of each manifold. The aluminum manifold has the expected large, 4V size runners. But, the iron manifold has the smaller 2V size runners.

Here's the two part trivia question:

1. Which specific motor or Ford automobile was the aluminum manifold installed in.

2. Where was the iron manifold cast?

Bill,

there was a Holley "square bore" version of the aluminum intake as well, the part number cast into the runner for cylinder #1 should read D1ZX-9424-DA. That number is from memory, so forgive if I'm off a digit or two, but I'm fairly certain about the -DA suffix. I've installed several of them over the years. The casting number of the intake in the picture is D1ZX-9424-CA.

A previous owner must have installed the aluminum intake, as the oem intake for your motor was cast of iron.

Your aluminum intake is a good intake by the way, worth $300 or more. There's one business notorious for being high priced that lists them for $500 (Perogie Enterprises).

Okay, back to the quiz, doesn't anyone find it unusual that a 4 barrel intake manifold has the small 2V size ports?

The only that I find unusual, is how you remember a part # for an intake. OK how about...The cast Iron is designed for use with 2 bbl heads..but why?

lol....I know, I'm a complete Ford nerd! I'm an amateur though, some Ford guys have hundreds of those numbers memorized.

Yes, the intake is designed for 2 bbl heads, why indeed!!!! Provocative question Bill. The cast iron intake IS a Ford intake. It was installed as oem equipment in Ford vehicles. DeTom may not have been correct about it being cast in Cleveland. Even though the motor is called a Cleveland.

Thanks AJ, what a kind thing to write. I have to laugh, because I would like to know what I've forgotten as well! Smiler

I took a deep interest in the Cleveland engine back in the '70s because it was the power plant in my dream car. It was quite an exciting engine back in the '70s, as it made more bhp per cubic inch than any other American OHV V8. It would have dominated many forms of racing except the racing associations kept penalizing cars with Cleveland engines, with higher weight limits and/or restrictor plates. It has an amazing set of cylinder heads on it. It WAS the right engine for the Pantera, don't let anyone ever tell you differently.

Actually, the art of building performance engines continues to improve, change and develop. There are new things to learn constantly. I'm still learning. which is why I also hang out on the Cleveland Forum. I also read technical papers on a constant basis. There is just too much to know and keep track of. Technology is advancing at a very rapid pace.

Okay guys, I don't want to give this away too early. Which motor or car was the aluminum intake installed on; AND where was the iron intake cast?

George, Tha cast intake is 2V with a Holley 4V for a boat.

The Aluminum 4v with a small primary and large secondary's is from a 71 Torino ??

Wrong on both counts Ron. I'm not asking for the application of the iron intake, just where it was cast.

Heyyyyyyy! Look at those Webers in your avatar! Cool.

DeTom was correct about the aluminum manifold, it is a 1971 Boss 351 Mustang manifold. Bill, I had one number in error, the correct part number of the manifold is D1ZX-9425-CA. This manifold is rather rare as only about 1800 Boss 351s were manufactured.

The iron manifold was cast a very long distance from Cleveland Ohio, it was cast in Geelong Australia. CLEVELAND engines were manufactured in Geelong Australia by Ford from 1972 to 1982, for use in the Australian musclecar, the Falcon!

Falcons were equipped with Cleveland motors from 1970s XW model through 1982s XE model. The entire model range is XW '69 - '70, XY '70 - '72, XA '72 - '73, XB '73 - '76, XC '76 - '79, XD '79 - '82 & XE '82 - '84. The XW & XY were sedans closely related to the American Falcon. The XA represented a fresh design, as the American Falcon was last manufactured in 1970. The XA, XB & XC were available as coupes, Mad Max drove an XB coupe. The muscle car era lasted much longer in Australia than it did in the US.

Cleveland engines manufactured in the US were exported to Australia during the entire US production period, i.e. from 1970 to 1974. Clevelands installed in 1970 and 1971 Falcons were sourced solely from the US. Australian production began in 1972, so the Cleveland engines found in Aussie Falcons from 1972 to 1974 are a mix of both American and Australian manufactured motors. After 1974 the Cleveland motors found in Australian Fords were sourced solely from Australia. The 4 barrel carbureted motors with the large port "4V" heads were only manufactured in the US, therefore after 1974 there were no big port Clevelands installed in the Aussie Falcon.

Clevelands were produced in 2 displacements in Australia, the 351 cubic inch you are familiar with, and 302 cubic inches as well, that's right, a 302C. This engine is the source for the closed chamber 2V Aussie cylinder heads you have possibly read about.

Australia began producing Cleveland motors with 4 barrel carburetors in 1973, the Aussie 4 barrel engines utilized the small port, 2V heads, hence the existance of the manifold in my picture. The 4 barrel motors produced from 1973 to 1975 utilized the "square bore" Motorcraft 4300A carburetor, Cleveland 4 barrel motors manufactured from 1976 to 1982 utilized a "spread bore" Carter Thermoquad carburetor for emissions. This latter manifold is more common, easier to find, and less expensive to purchase. Most, if not all, of the spread bore variety of manifold has provision for exhaust gas recirc, and is not desireable as a performance manifold. The "square bore" manifold in my picture is getting harder and harder to find, a is worth much more money. It is considered a better design than the Edelbrock Performer. Its runner design resembles a shrunken version of the Blue Thunder intake manifold. But, as it is cast in iron, it is a heavy SOB.

A little Cleveland history lesson for you.

Now, for being good sports and playing along, your reward. The full size picture of Nora!
