I have heard them called that before but I'm not sure about it. I think the early S10 4 cyl. were also called that and they are different.
You are correct about the boat thing. I wanted to make sure it has a pre-emission date on the block.
the iron duke was in the 1976 chevette and yes boats i/o drives i have an iron duke in my 1982 z/28 now and am looking for a nother motor to slip in while i freshen the original motor so we both are looking and yes the early ones are better then the later as the head got changed around so i will keep shopping for us both maybe a deal will work if we can find a pair thanks guys

The 153-cubic-inch (2.5 L) 153 was an inline-four engine which was designed for use in the entry-level Chevy II/Nova. It is a four-cylinder version of the Chevrolet 230 inline-six. Usage of the 153 lasted through 1970 because of low demand (the motor was used as standard equipment with the Kaiser Jeep DJ-5A which was used by the United States Postal Service until 1971 where the 153 was replaced with the AMC inline six after Kaiser Jeep was purchased by American Motors), after which the inline-six was made the base powerplant with the Chevy II/Nova. Currently, descendants of the 153 are used with industrial (forklifts or generators) or marine applications.
The 153 has a bore of 3.875 inches (98.4 mm) and a stroke of 3.25 inches (82.6 mm). The firing order is 1-3-4-2. A later variant of the 153, the 181, used a larger 4-inch (101.6 mm) bore and a longer 3.6-inch (91.4 mm) stroke. The 181 (branded by GM as the Vortec 3000 for marine or industrial usage) was never installed in passenger cars (later variants of the Vortec 3000 had modified cylinder heads where machined bosses were drilled for use with multipoint fuel injection). The 153 engine is entirely different from the later Pontiac 151-cubic-inch (2.5 L) Iron Duke, but the two are often confused today. In South Africa, smaller displacement versions of this engine were also built. The larger one has a displacement of 2,319 cc (2.3 L; 141.5 cu in), and a stroke of 3 in (76.2 mm) with the same bore.[1] There was also a narrow-bore 1,960 cc (2.0 L; 119.6 cu in) engine which has a bore of 3 9⁄16 in (90.5 mm).[2] This is also the bore used for Chevrolet's closely related "194" six-cylinder engine.
TMJ i am from chatham and do alot of scouting in the usa for part for others along with myself i do know were there is a rebuilt iron duke that is done read to install but i am not ready to part with that much for just a temp motor till i face lift the duke in the z/28 thanks bob

yes there is one advertised He actually has 3 of them. He won't split them up yet. I have told him I'm in for the re builder if he sells them separately.
I don't want a couple of grand in a 4 cyl. on a stand.
TMJ i found three last night in the usa 2 were good prices and one is a new rebuild and if our dollar was better it would be a buy but not now the other are good price but aways away to get i did find a new rebuilt head for mine in Chicago for under 200 dollars and mite go get it as mine in the z/28 is fine but has a broken boos at one of the exhaust bolts and is letting the exhaust seep out and dam i hate that noise lol
thanks bob
I believe the "Iron Duke" is different than the 4 cyl Nova 153 engine. I went to look at a Nova 4 cyl that has high compression pistons and weber carbs on it but the guy wasn't home at the time. He's asking $1200 but motor not ran for a number of years so you would want to go thru it before you install it.

that's the one I was talking about that has 3 but he won't sell the rebuild-able one separately yet.
