Anybody have some- preferabbly hot rodded in an early ch***is. Finally got one for my A and looking for mounting ideas. Thanks Jim Enough with the debate on "Iron Duke" and not "Iron Duke"- enough people know I'm talking about a 153ci Chevy 4-banger so let's get over it. Just like the Chevy vs. Ford "Shoebox" debate- both are right depending on who you know.
Couple few months ago, somebody posted a pic of their 153 with a wild 4bbl intake that placed the carb above (!!!) the rocker cover, then the runners ran down to the intake ports in a loping semicircle. And IIRC, it was turbocharged too. I wish now that I'd saved that pic. Maybe somebody else has it saved. d
Jim, Ch***is Enginering has a kit designed for buick v6's that bolts on to the mercruiser motor ,it worked for me .
There was an article in a late 1970s Rod & Custom (I think it was a quarterly at that time). At the peak of the gas crunch, 1979 (maybe 1978?) they were bragging up the fuel economy benefits "new" Pontiac motor based on the old Chevy II motor. I remember, because I bought one for a '38 Dodge Bros. pickup that I never finished (the choice was finishing the hot rod or finishing engineering school). The model I bought was out of a 1980 Monza, and by then Pontiac had re-engineered it with a cross-flow head and a 4" bore by 3" stroke. Interesting little motor with screw-in rocker studs and push-rod guide plates. I'm not sure of the heads interchange or even if you'd want to do that. Same cl***ic Chevy barn bellhousing pattern. Anyway, back to your question... That article may have had some mounting pics. Another place to look would be installations of inline chevy sixes, since the iron duke was based on that motor.

The 153 (Chevy II) and 151 (Iron Duke - Pontiac) were two different engines. The only thing the two shared were lifters, the bellhousing bolt pattern, the OHV setup and the inline-four configuration. But yes, the 153 was essentially 2/3 of a Chevy 230 six cylinder, so it shared everything with that engine save for the rocker cover, block, cam and crank. d
JimA, if you will do a search on "fourbanger", I posted the pictures of the 181 c.i. four cylinder that was turbo charged. This motor came out of an OMC inboard and when we finished, it was 201c.i. We used the side mount bolt holes and took a piece of 3" X 3" angle iron and trimmed it down and mounted it to a donut motor mount. It seems to work just fine.
it is quite common for the old Chevy 4 bangers to be called "Iron Dukes". i don't know when or how they started to be known by that name but i know quite a few guys that have been building rods and using the little Chevy 4s for more years than i've been alive, and they all refer to them as the "Chevy Iron Duke". we even got one from a friend for my little bros modified. it's all Mercruiser marine stuff in a Chevy II block. point is. it may not have been givin that name by the factory but it has become known by that name over the years and it is perfectly exceptable to call the Chevys "Iron Dukes". by in large most folks (car folks that is) will know exactly what your refering to when you say "Chevy Iron Duke". now lets see those pics...
Lots a talk- where's the pics? I've heard Chevy II 4-bangers called "Iron Dukes" since before Pontiac even made that engine.
Improved version of the Pontiac Superduty-4 block manufactured by Kansas Racing Products in Chapman, Kansas. Displacement ranges from 140 cubic inch to 213 cubic inch or a maximum of 4.125 inch bore by 4.0 inch stroke. A KRP block can be finish-machined to accept most small block V-8 cylinder heads...GM, Ford or Mopar and the old Pontiac Superduty-4 cylinder heads. NHRA racers using a naturally aspirated 181 cubic inch engine produce over 400 h.p.
Cosworth made a dual overhead cam conversion for the Pontiac Superduty-4. It was mostly used in road-racing with IMSA and the Camel-Light Series.
I had a '62 Chevy II that had the 153" 4 cyl. The factory mounts were VERY soft rubber that let the engine shake it's little heart out! They were specific to the 4 cyl and were nothing like the 6 cyl mounts. I think the donut mounts mentioned would be the best bet. I would recommend mounting them as wide apart as possible to handle the "shakes". The stock 3 speed ****** mount was different for the 4. It used a different crossmember that mounted farther forward and hooked to the trans at the point where the tailhousing bolted to the trans case. It used two soft rubber pads also.
Here's my 153. Got a mer cruiser head and the marine intake thats been modified. The header is a tri-Y done by me.
