I am wondering what engines I have recently acquired. They were in the back of an old shed for years. The tag on one says: 429 69 4
9-D K815-U.
and the other says: 429 70 6
9-K K815-A.
Any help would be greatly appreciated!

 

Are there any numbers by the starter? If so, post those.

 

There are numbers on the back of the block that read: 9Z604674.

 

Numbers on the side by the starter are the ones I'm talking about.

 

Engine ID tags: K 815 U & KK 815 A = 1973 429 4V

 

The numbers by the starter are C9VE-B.

 

C -1960s
9 - 1969
V - Lincoln
E - Engine.

A 1969 Lincoln casting revision, with the B maybe being another revision. No surprise in a 1973 motor.

Deck height would be a question, as it appears there were several revisions, this possibly being the last for C9.. blocks. See the notes on deck height etc here:

Kelly hotrod - Ford Engines Page 2

Probably just a run of the mill pillow barge smog motor. Perfect for a minor rebuild into a 700 horse mountain motor. Get to work!

 

Actually some numbers aren't adding up. A C9VE block would be a huge surprise on a 73 motor. It should have a D1VE block.

And you can't use casting revision numbers to determine where it came from. Just because it has the V for Lincoln does NOT mean it was ever in a Lincoln but rather that the ORIGINAL use of that engine group was for a Lincoln

BUT the ACTUAL decoding on that engine tag indicates it's a 69 429-4V.

 

From the above tag decode:

Engine ID tags: K 815 U & KK 815 A = 1973 429 4V


OP needs to tear them down and inspect if he's going to use them anyway. He'll figure it out.

 

The motor I am referring to is a 1969 Ford 429. Not a 1973. At least that's what the tag attached to it says. I was told it could have been out of a T Bird but that may not be true.

429. 69 4
9-D K815-U.

429 70 6
9-K K815-A"

OK, if I read this correctly, you have a '69 made in April of '69 and a '70 made in October of '69.

AFAIK those would have been 11:1 compression engines, T bird, Galaxie or Mercury land yachts.
Does it have a 4bbl intake and the words "Thunder Jet" on it anywhere?

The Lincoln connection would be that the 429 and 460 blocks are the same, with Lincoln using the 460 at that time.

As I said earlier, since they have been sitting and since you don't know the condition, a tear down would be a good idea. Also, they probably do not have hardened valve seats unless someone did that later, and with 11:1 compression, they will be hard to please gas wise.

 

It has a 2 barrel manifold on it. No thunderjet anywhere.

 

There were Mercury 2bbl 429s, not sure if they found their way into Fords. The Marquis had one as the standard engine. Supposedly the same specs and a "Premium Fuel" engine with the same compression as the 4bbl.

The insurance man would relax if you had a 2bbl, but panic with a 4bbl.

Also, I see 11.3:1 compression referenced for the "Thunder Jet" motor, a figure I recall hearing years ago when these motors were new.
