Engine numbers

[Conrad W Peden]

I'm a 4cyl guy so this may a stupid question but I looked around and couldn't find any what I was looking for.

Just received an engine with #'s 6190446 at the front and *6400653* near the back.
What does that tell me about this engine?

6=911
1=911T
9= 1969
0446= sequential number

[strictly]

the back one you meen is about 5 oclock on the cooling fan, near the oil temperature sender right?

Ive never ever seen the front one! Post a picture!

Thanks, I guess that would have been a 2.0L then?

front one is below Alt stand, the Back one is "between the oval hole and the round hole"?

This^^.

We need to see where these two numbers are located on your engine

edit: I believe the 640xxxx number is from a 914 engine case. Those numbers are found on the top of the case, by the oil breather. You may have an engine made from two different cases--one from a 911, the other from a 914. If so, you will have no real clue as to what is on the inside.

I'm confused i take it it not a 911 engine? or its a 914/6 which has numbers in a different place, ive only ever seen the *XXXXX" number which is near the oil temperaure sender/right cam line, the other one ive never heard off, besides the 3 or 4 digit case numbers stamped on each side of the case (to indicate matching cases).

yes please to pictures of both!

I believe they are both on the same case half

IIRC, the site for the 914 number and the site for the 911 number are on the same side of the case, so you would not have two separate halves. Most likely the 911 number was stamped on a blank area because it would not have any markings there if it was a 914 engine.

Further looking makes me think the front number is fake. The digits look too large and there are no stars before and after the number.

Agree - no stars - not factory stamping

Hmm, the plot thickens....I'll throw this by all my 914 mates on the World site and see what they think.
