Big blower, Merlin, Griffon? Application would be high altitude fighter or bomber, horsepower would be >1800 from the looks of it.

Nope. Great guesses! :yes:

(Update: Henning got it, its a Rolls Royce design, licensed to be built in the US by Pacard called a Merlin)

It would make a hell of a go kart engine. :eek:
 
V-12 something..;)...


I want one to stuff in my Zenith 801..........:yes::yes::D
 
If it isn't a Griffon, it's some sort of knock off. Klimov maybe?
 
My bad!

Henning got it right. I thought it was a Rolls Royce. It is a Rolls Royce engine, built by Pacard called a "Merlin".

Good guess Henning! :happydance:

Yep!

We sent this engine to a shop to have it broken down. Good parts will be salvaged and the core will be built into a coffee table for a friends hangar apartment.

Yeah, Packard made the Merlin under license during WWII. I'd hate to see that particular one turn into a table, that is a very high horsepower version, with that blower at sea level, that engine could propel a butt load of fun, especially on alcohol.
 
Obviously a Rolls Royce product, an Allison has different looking valve covers and distinctive looking induction tubes on top, the Daimler is an inverted V-12 and really different than the first two.
 
You should keep that Merlin intact and find an Allison to destroy.

The Allison is much more beautiful inside, with better quality machining.
 
Do you know which plane it came out of? The blower with inter cooler on it is interesting, I hadn't seen one with that one before, it's a honker. I'm thinking a Pacific Theater P-51 for B-29 escort. The only bombers I recall using them were Lancasters, and I don't know if any of them got Packards, but they may have.

It is off a P-51 Mustang. :yes:

The engine is going to a rebuilding shop and they are going though it. The valve train, mags, reduction gear assembly (front, out of view) have all been salvaged. From what I was told the crank is the only salvagable part they are looking for. Trust me, these guys know these engines and what to salvage. We are going to be working on the display table in a couple of months.

Did you see the intercooler? Upper left. These are amazingly complex engines.

Is it a Merlin or the Allison version? It could be an old PT boat engine if it's an Allison. I think they had twin Alison's. What horsepower is it? They got much more powerful as the war went on. The bomber engine had heavier cases I think. They are prized today as rebuilds.

Read the posts above, it's a Packard Merlin.

All of the US Navy PT boats built during WWII had three Packard 4M-2500 marine engines.

PT and ASR (Air Sea Rescue to pick up downed airmen, same hull, different weapons lay out) boats had both Packards and Allisons. They used 4 engines on three shafts with the center shaft having a twin drive box with two engines on the shaft.

I bet they moved!
 
And after the war, almost all of the surviving ones in the pacific were rafted up and burned..... :-(

Heck, there are still lots of them operating today in the US sport fishing fleet. They mostly run 2-3 much lower power diesels in them.
