I put an engine in my CA that I heard may have come out of a combine.It has bigger manifolds and carb.Numbers on the block are 149-12007m behind air cleaner,H88 under the mag,AM4339-5 in front of oil filter.Anybody know what I have? Thanks.
 
Might be a 149 cu in d-10/12, or 14 motor. Rub a little higher, on the serial # spot, if it was a tractor motor, originally, your serial # might start with D10, 12, or 14.
 
I looked again and didn"t see any other #"s.Block is very clean and painted.It bolted right in my CA, with the exception of those bigger manifolds and the oil filler tube in the valve cover.I just wanted to know what this motor is so I was running the right plugs and points.Also wondering if its the same HP as a stock CA.
 
You have a 149 cubic inch engine from a D-10 D12 D14 or D15 If it came with a flywheel it wouldn't have fit unless you removed it and installed the CA flywheel. Bob
 
HP is a little higher. If I recall right, that motor started out, in the early B's, with 125 cubes, then increased the set Rpms, to 1650, with the first CA(22.5 HP). The first D-10's had 138.7 Cubes(28.5 HP), the series 2 D-10's had 149 cubes, Final HP 33.4 HP
 
Thanks for the info. on the 149 cu. in. motor.Now is there anyway to exactly know what it came from so I know what points and plugs belong in it?Also interested in its HP rating.The rumor was when I bought it was, it came from a combine.I googled gleaner combines and it showed they had 149 cu. in. motors in some of them,but I could"nt find anyother specs. on it.Thanks.
 
Post a picture of the right side of the engine making sure you get the all of it front to rear.

Starting with the CA thru the D 10/D 15 the four bolt holes where the front end bolts to the block were 5/8" rather than 1/2". To bolt the front onto the block the studs would be stepped studs from 5/8" that screws into the block down to 1/2" to go thru the front casting. Before the CA the studs were 1/2" course thread on one end and 1/2" fine thread on the other.
The D 10/ D 15 block is different below where the distributor bolts to the block.
 
Hope this picture helps.

That is an engine block from the D 10/D 15 group. When it jumps to the larger engines the block bolt holes do not line up with your CA torque tube. The CA engine block does not have the plate under the magneto like your picture.
 
You can choose the D 15 charts and will be good to go for plugs and such. With out looking I would guess it would be the same as the CA also.
Been a while since I had a D-15 here.
 
You might want to find a d-series distributor, and replace that mag, for ease of service. Then you can convert to pertronix system, and never have to worry with points, again.
 
You might want to stay with the CA distributor if you decide to switch. The D series distributor housing will have the open end for the tac cable. Other than that they are the same.
