I have a neighbor selling a 1966 dune buggy with 1700 miles.
It has a 1966 911 2.0 engine he describes as P74474.
Anybody have an idea what this designation means?
The carbs were just rebuilt.
What is this engine worth?
How difficult to transfer into a 76 914?
Any other insight from the group?
Thanks.

Not to be too bold...but what's he asking for the Dune Buggy? I'm just curious...as this could be an easier decision if he's really cheap on the price.

If the numbers check out, that engine is going to be more valuable to the restorer of a '66 911 than any other application. You could probably sell the engine and make enough to do a proper -6 conversion on your 914.

Since you say '66 2.0 I'm assuming it's a /6. If it has a aluminum case it could be worth grabbing if the price is right.

Really it will not be any performance increase over a 2.0 /4 engine and it's all the "other stuff" (tank, lines, mount, tins, etc.) that makes a /6 install pricey.

If the engine is a 1966 911 engine, it would be a sand cast case and worth cash. The serial number will tell if it is actually that early an engine.
Engine alone could be worth enough to buy a running 3.0 or 3.2 engine if it still retains most of it's early parts. Depends on how modified it is.
Engine number should start with a 901 or 902 number.
More research needed to tell for sure.

Pictures of engine would help a lot.

Just as en example, I posted questions about the 2.2s engine that came in my 914 on the early911sforum to get more info. I had offers in the $7k range sight unseen.

A Sand Cast Aluminum Engine is easy to identify - there are Cooling Fins in the bottom of the Motor & the color of the case is different. These are worth some $$

Buy it, sell the vintage 6cyl. Engine on Early911registry, sell the roller dune buggy on Samba.
Then take your cash and have a 3.2 motronic put into your 914 !
You should come out very well "Moneywise".

Last I checked, those engines are going for $15-20K.

Sell it and buy a rebuilt motor (2.4 - 3.0) and use the rest of the money to finish your six conversion. You'll need tin, motor mounts, a tank, etc.

That's NOT a valid engine number for any 911 engine. The engine number is stamped on the right side fan housing support and will have 6 digits. The type number will be stamped on a horizontal surface within 3 inches of the engine number, just forward and to the right (901/xx). I suggest you go look at it, verify the numbers, and look at the bottom for the characteristic longitudinal fins.

I doubt the dune buggy has an oil tank. Probably a 4 cylinder engine.

You're right. 1959 1600N. Zenith carbs, 60HP. Done right, $10-12K for a complete engine, which is about what it will cost to go through and completely equip one that's been in a dune buggy. Been there, seen that.

We have a winner.
After looking at it, it appears to be a 1.6 from a 912, not a 2.0 from a 911.

If it is a real 356/912 engine, it is still worth money.

Yep, Still worth a lot of money to a 365 guy. They unbolt the piece with the engine number and bolt on a reproduction piece with the correct # for their car. They will pay dearly I guess.
