Early 911 motors - I just picked up #490

[RSwannabe]

I just picked up a very early 911 motor - type 901/01, #900490. It has the solex mechanical fuel pump and freeze plugs in the holes in the cam covers for the center feed oil lines. I know this has the sand cast aluminum case, but what else was different about these early motors?

Anyone looking for this one for their early '65 911?

Can anyone tell me what the "390" under th type code means?

390 is the production number. For the very early cars it is 100
less than the engine number.

Brooke,

the "internal number" is explained in this thread:

http://www.early911sregistry.org/for...ighlight=davep


It is the sequence number for when the engine was made.

It was installed into a car in about the 1st or 2nd week of February 1965, around car number 300 400 or there abouts.

Example:
Car 300 401 had engine 900 445.
Car 300 402 had engine 900 492.
Car 300 366 had engine 900 494.


**** Be sure to add this with the parting numbers and casting date to DaveP spectacular engine study****

Hope this helps.

Bob and Andy,

Thanks for the info and the link to the other thread on these early motors. Pretty cool stuff. I've posted the motor info to the other thread, except I cant find the case casting date. Bob, do you know where on the case that should be located?

The case half numbers for this motor are #553.

[RSwannabe]

Hmmmm, well I checked the correct location for the date stamp, and no stamp. Here are a couple of pics of the area.

[RSwannabe]

I did confirm the heads are date stamped November 1964. that combined with the fact it is still wearing its solex mechanical fuel pump leads be to beleive the motor is pretty much an unmolested early motor.

So, as I have learned more about how early and complete this motor is, I am thinking it is not a good candidate for a hot rod motor project. I have had a few people ask me whether I would sell it to them. I think I am inclined to sell it to someone who needs an early motor for their early car.

The motor does turn over by hand (not particularly smoothly though). It has the original heads and I am assuming all the original internals. It does have the solex mechaical fuel pump, but it is missing the carbs and manifolds. It is essentially a complete longblock.

I am not inclined to have an auction for the motor, but I also am not quite sure what this is worth. Do people have opinions on what a fair price would be?

Thanks,

If you don't put up a premium for it being very early but just an early sandcast engine I would think it's worth $2250-$3000. You have the case, the crank (which I hope is good) and the rest of the internals. In general 2.0L heads (small ports) are not worth much, but the rest of the sandcast engine parts are worth something.

I agree with what Richard wrote, that was for the whole long block. If you take it apart, you can determine if the crank is good; you may want to sell it parted out. It would be nice to sell it to someone that has a chassis that's engine is close to yours. I agree too, it is probably too early to use, to "waste" for a hotrod engine. All IMHO.
