I wanted to buy a 'visible engine' model, but I was thoroughly confused by the many models available. To create some order in this chaos, I gathered all my information on this page. It appears that most visible engine models have been around for a long time, and they have been issued many times under different brands and in different boxes.

1/4 scale Studebaker 259/289 V8 (previously listed as Pontiac 371/389) | ||||
|
The model has moving pistons and connecting rods. The camshaft operates rocker arms and valves. Rubber fan-belt and vinyl ignition wires. Includes display stand. Ebay seller Stunnuts sells a CD on how to build this model properly.
Often thought to be a Chevy block, it was previously reported that it mostly resembles a 1958 or 1959 Pontiac 371 or 389 engine (matching exhaust manifolds, alternator is on the left) or the Packard V-8 (matching valve covers, but the Packard alternator is on the right). Monty Montgomery made a very thorough analysis of this model's 1:1 scale inspiration: The engine is a mashup of a couple different 1950s V8 engines - they all looked kind of similar. There's one big difference with the real engines: the Visible V8 has the right cylinders offset to the front of the left cylinders, which is the opposite of every American V8 I know of. I'm currently building a 'dressed' version of the engine with a bit more attention to sorting out what parts came from where and decided it was mostly a Studebaker, so that's how I'm building it. Going piece by piece, the engine is maybe 80% Studebaker 259/289. The unmistakable bits that had no real counterpart in another engine are the crank, geared cam, valve design/shape, and water pump. Several other bits match Studebaker, but also match a few other engines, like the straight/central oil filler, fuel pump on the left, balancer shape, plug placement, etc. The classic up-front Studebaker oil filter isn't there, but there was a dealer-installed full-flow option that did locate it on the right side where it is on the Visible V8. If you move the generator to the right side of the engine and paint the red parts to a Studebaker engine color (they changed often, but were never red), you have to look close to see anything but a stock Studebaker. That said... The fan detail closely matches a 1950s Chevy 389. This plus the engine originally being red is probably the only thing that's 'Chevy-ish', but I'm sure anyone who owns a Chevy notices that first :-) The transmission is a first version GM Hydramatic (I think at the time that would have been primarily on Cadillac). The carburetor is a Rochester 2GC, that also would have been from a GM engine. The starter motor shape and starter/generator position are classic Oldsmobile Rocket 303. The generator itself is just a generic Delco. Many parts don't really match anything. The intake manifold and headers are just sort of a blocky generic design. I don't see any resemblance anywhere in the engine to a Pontiac. The Pontiac engine designs of the time were kind of unusual in several ways, and all the signature things that made a Pontiac V8 a Pontiac aren't there. I also don't see any resemblance to a Packard engine except in a generic sort of way. Packard and Studebaker merged in the 1950s, but the engine lines were kept separate. Note that Revell also made a working store display of the Visible V8 engine. It was a flat box showing a cross section of the engine, with lighting to show the spark plugs operating. Catalog number is B-905, and it was issued in 1979. | ||||

| Issued late 1961 together with six Chrysler car models representing the whole 1962 line-up. Tooled from Chrysler blueprints, it had very realistic engraving and details, much better than the generic Visible V-8. Approximately 300 parts molded in four colors: black, red, silver and gray. Several parts can be removed to show the functions: the valve cover, the oil pan, the intake and exhaust manifolds, the left side of the cylinder head, and the left side of the cylinder block. The A903 three-speed manual transmission houses the electric motor that drives the crankshaft, pistons and valves. Light-up spark plugs timed through the distributor. The MoparMax site has an excellent article on this model's history. | ||||

| This is a German model from the fifties, that was to be assembled with the supplied screwdriver and wrench. The see-through engine block, sump, and head are made of plastic, all other parts are metal. By turning the handcrank the pistons, camshaft and valves are operated. The 3-volt battery powered spark plugs fire in sequence. The engine is fitted with a working three-speed gearbox with reverse, and even a clutch that is functional. Combined length is around 15 centimers / 6 inches. The engine is mounted on a steel base. There are two accounts of the inspiration of this model. The first one is that it is a Ford Model T engine, the second that it was patterned after a pre-war Opel engine. Philippe de Lespinay has a great webpage on this engine. | ||||

| Judging by the look and colors, this appears to be a 10A model as fitted in the Cosmo 110. The same engine was also fitted in the R100 and early RX-3 but with a blue air cleaner. Parts to engine include an air cleaner, fan, fan belt, generator, starter, stick shift, and transmission housing. Runs on two batteries. Includes wiring and vinyl tubing. Reported inaccuracies: "the rotors are wrong dimensions, the internal gears are fake, eccentric shaft is all wrong, all of which has to do with making it turn over via the electric motor. Not a bad kit and at least they got all the external stuff close to the 1:1 prototype." | ||||
