Early Engine, more pic's

[Jim Parker Toronto]

In the interest of "Preserving History", and not wanting to misrepresent anything, I took some more pictures today to show and get some opinions on. There is NO paint on the block, so that the green/gray debate is still on! There appears to be blue sealant on the rear main bolts and brown primer under the nicely painted black oil pan, so I would summarize that the pan was off and the mains/rods were checked for clearance. Is there anything someone wants to add or need more pictures of? Jim

Interesting; 3X plug cores are Not made in Canada, & are 30-31 style with later bases...Complete 2nd type dist assy. & so much for the condenser plug.. Early head with stop boss..The intake looks ODD with a weld line around lower half ??.

Is it my imagination or did they cast the block in three places? The pic. of the front part of the block shoes the seam off to the right then the curved portion over the timing gear and third line that is angled between the two.

I will have a closer look at my car over the weekend, its about a 1100 earlier than that one also a CA.

I have Firestone plugs as well as some Champions. What was fitted from the factory.

Thank you so much Jim for the photos. How long is the pad for the engine number?

It is remarkable how good of shape that engine is in.

The head is not early, the plugs are interesting. From the previous photos posted,
I thought I could see " blue sealant " on the rear main bolts, the new photos show
it clearly. I think the crank has been out, VERY clean, cotter pin missing from the
fly wheel housing. Still a super find with great parts.

Very interesting way the lock wire is routed in pix #6

Fred, I checked a couple "humpy" intake manifolds. They all have a line from the forging.

 

[d.j. moordigian]

Dean,
My " humpy " doesn't have the line, BUT, has the taper at the block side. Are yours
straight at the block?

* I think the parts all work for an April of 1928 engine *

 

[Jim Mason]

the plugs (at least the bases) are repop

 

[Gary Karr]

Also, notice that the intake manifold, although an early '28 style, does not have the threadded and plugged hole, nor the early oil return tube, as indicated by the JS&RG, revision 3.

The engine pad measures 2 1/8" x 15/16".

Gary, I did notice the return tube, along as stated, the oil pan ?? Wonder Why ?.. Also notice the carb does have the later lower leg.. Wonder if its a double V.. I guess I blew it on the head !!

 

[Jim Parker Toronto]

Can maybe we get a third opinion here about the Head? FRED says it is, and d. j. moordigian says that it is not. I think it is...........

Looks like you have your 3rd opinion

Hopefully this photo isn't too big. In a matter of weeks I have forgotten how to insert photos.

This is a head on Plind's A2820. As you can see it has the pronounced boss for the distributor set screw.

 

[dean from bozeman]

D.J. I looked at the two humpy manifolds here at the house. One is tapered at the block side and the other isn't. I had never noticed that before. Now I must go down to the garage by the barn and check a couple others.

 

[Fred]

YUP, as I said, I blew it !! New It When I did it !!..

 

[dean from bozeman]

John, in regards to the spark plugs the knurling doesn't go down to the base. When I first saw this I had my doubts but am waiting for someone with definitive knowledge to speak up.

Gary, I think that this engine wouldn't have the earliest oil return tube. I've only seen them associated with 3 digit cars.

As far as the threaded hole on the intake manifold, Steve Ciccalone had talked about this very thing the day before he died. We talked about a possible correlation between early gas tanks that had the hole in the firewall for a vacuum line and that hole. Other early gas tanks don't have the hole in the firewall. Some of these early A's belong with Alice in Wonderland because they make me curioser and curioser.

Overall, this engine is quite a time capsule. Yes, it does have a few parts that we would not expect on it. Now did it come like that or where they changed through the 80 years since its "birth"? Only the shadow knows...

My understanding is that the early heads are missing the peanut shaped hole in the middle.
