IIRC the drone engine is 750cc 4 valve per cyl design

Actually it is supposed to be a 2 valve per cylinder design, but with Hemi head/piston design. It was claimed to produce around 63hp as well.

Maybe "I" have less projects and more time than you do Chuck (how is that possible?)! I just don't have the money.

So feel free to head down to Birmingham, pick up the mill for me, and I'll take care of the rest!  ;D

Could take me awhile to figure things out though... I'd need a lot of parts to complete a project around that engine.

This same engine has been up for sale before, somebody here needs to rescue it.

I'm thinking more like putting it in this..



although a new 750 lump in the Lario would look good, too. Just the same, both would be projects, (the Lario not so much)  I'm going through the Strada this winter, and unfortunately.. w w w work is picking up. ;)

As said, the V75 Hi.e is a V75 with hemi heads, almost identical to those of the big block, is evident the advantage in the diameter of the valves.

The ad has been on CL for a few months, every time I do a search for Guzzi, it comes up.
A few years ago there was another one for sale out of Dothan, Al. I think. Ft. Rucker is just up the road.

If I recall Ed Milich had a funky cam from a drone engine and mentioned they ran in a reverse direction to the motorcycle engine, this could make a first ride interesting.....

Man, this hemi head design looks like it is begging for a V7 Stelvio.  That's the missing ingredient for a competitive 750cc machine.

If you double every dimension of a cylinder, the cross section of the valves increase 4 times, but the volume to fill increase 8 times.
In the original V35/V50 the cylinder was small enough than the dimension of the valves of the heron head was enough to fill it without problems, and the heron head, with the tecnology of the time, was way more economical (the tools had to work in only one direction). But, as the displacement increased, the heron heads were no more adequate, also because the 80X74 V75 is a long stroke (and so, small bore) engine compared to the 66X50.6 V35, so the valves are comparatively smaller. Bigger cross sections of the valves, and so the hemi heads, or the 4V heads, are needed to keep it competitive (infact, the V75 was born with the 4V heads).
Why it has heron heads in 2013, only the Gods know...

Totally unsuitable for a manned aircraft the way it's shown there. Those heads dont have dual plugs,dual ignition is a must for a manned aircraft.

Apart for the hemi heads, the pistons, a dedicated camshaft, and an extended sump, the engine is a standard V75. In the Ippogrifo it was coupled with the (will be) gearbox of the V11.

If somebody bought the engine in Alabama, they should disassemble it and get those individual parts scanned... that way they would have a 3D backup of each piece, could make replacement parts if necessary, and maybe they could share that information with other small block owners so they could make their own "hemi" small blocks!  ;-T

Thanks for the pix, Dogwalker. I'm having a tough time deciding if I want to deal with the issues of converting it to put in the Lario. Do you happen to know what compression ratio it is?

9.75/1. Is a bit low since, for military use, the engine was designed to function wit low grade fuel. With this spec, the engine is claimed to have +31.25% power and +10.6 torque over a standard  V75 2V.

Sounds good. I was afraid of it possibly having super high compression to run on 100 octane or even 130 (!) No computer with it. The guy is going to send me some pictures tonight.

Leave the Lario with its original motor. THEN, rig up the additional motor on the back with a pusher prop! Finally, hang on. ;D

I'll volunteer to be a pair of hands if you need any help disassembling, reverse-engineering, or staring at the Hemi aero engine once you've got it in your garage Chuck.

I'm not a great mechanic, but I can hold your beer and bring food, etc.  ;D

I'd be a part of Moto Guzzi history, as wouldn't you be the first person (besides maybe the factory for the prototype Ippo) to put the drone engine on a bike?
