engine identification

[Paul Payne]

Does anyone recognize this engine? Been in my parts stash for years, got it in a parts box and always thought it was an Allison, but maybe not? I also have no idea what the big transmission is from.

[deuces wild]

It does look like an Allison...

 

[Classicgas]

I agree,  Allison.  The transmission looks like a big rig one, perhaps a Spicer.

Definitely not an Allison. And not 1/25 either.

This is the AMT 1/25 Allison. Sorta similar, but actually entirely different.

 

 

Judging by the sump and the angled cylinder head tops (relative to the exhaust ports), your engine appears to be a Rolls Royce Merlin, in perhaps 1/32 scale.

Maybe one of Revell's 1/32 aircraft models? The Typhoon has a Napier Sabre.

Wow- thought it was big in 1/25th scale, in 1/32nd scale it would be huge!

The V-12 aircraft engines from WW II were indeed huge.

The Merlin was 1650 cu.in, the Allison 1710. So roughly 3 to 4 times the swept volume of a typical big-block automotive V8. Add the superchargers, speed-reduction gearbox for the prop, and the accessory drives...huge.

There have been several 1/32 models of the P-51 and Spitfire (which both used the Merlin) that included engines. I'm not familiar with all of them so can't tell you which one this might be. 

[Foghorn Leghorn]

This is a WW2 Merlin V-12. I would die to have this thing in my garage.

what's he doing with the piping running into the shorty exhaust pipes? burning blowby?

A friend of my son's has this Merlin in his garage: 

Here's my kid and his buddy:

It’s good to have friends with lots of cool toys. ?

Now that we know what it is, does anyone want it? It IS missing a lot of parts.............................

[Classicgas]

Actually 1/32 is smaller than 1/25.

Yup.
And It for sure is a Rolls Royce / Packard Merlin.
Airfix had Merlins in 1:24th scale in the P51 Mustang and Spitfire.

It looks like a 1/32 Merlin/RollsRoyce engine, I cant identify the large bell shape housing in the rear. the round part lying behind the engine is wheel hub from a WW2 plane.

The tranny is a truck kit tranny.

AMT's Allison, MPC/Airfix spitfire merlin and Hawker engines in front of Bandi P51

The bell shaped husing is a part of the two stage supercharger the Merlins had.
