235? 216? none of the numbers seem to make sense

the numbers on the block behind the oil stick/dist dont make sense. seems to be some kind of wierd G(?) or unconnected 0. the rest is this:
G(?)ON 1 12255. what is it

 

not sure but you have two posts going..........

 

The number behind the distributor on the machined surface is the engine number. The leters give you some info about where it was made. The numbers you want are cast into the block. A picture of the right (pass) side of the engine would help. Casting no. for 235 could be hard to find down low on the front of the block, right side. 216 numbers bigger, back near the starter.

1955 motor manual has g as first letter in engine no. denoting 1949 216 engine. hope this helps

 

Ok, found some more numbers. What do these mean? 3837004 CM5T

 

If you don't get an answer here go ask on chevytalk.org - those guys helped me with my motor info. ~ good guys.

 

It may be GM 5 T

 

It is GM 5 T. what tranny is stock to that motor

 

That's a 55-57 235 engine block.

 

What he said. Here's a decoder:

Ok, thank you. I'm confused about the transmission that came on it. What was the stock transmission? The reason that I am asking is for an automatic swap. None of the linkage is on it and I cant seem to find anywhere to figure it out.

 

When you post numbers, tell us if they're cast numbers (raised) or stamped into the metal with a punch.

The short casting numbers like CON 1 and GM 5 are used for the casting foundry, and don't identify the engine.

THe long casting number like 3837004 tells us what kind of block it is.

There should be a short casting number sequence with a letter and two to four numbers that will tell you when the block was cast, such as B 15 8 the last digit is the last digit of the year it was cast.

The stamped number near the base of the distributor will tell us what kind of engine it is, for example displacement, manual or auto trans, car or truck, etc.

 

ok, thanks. Lets try this....
on back near starter and tranny bellhousing : CON 1 12255 cast

to left of base of distributor: OI37672T56X stamped

to the left of fuel pump: 3837004 GM 5 T

 

56 is the year, X is the suffix, which is for a standard truck 235.

So I'd say it's from a 56 truck. The number L or I 22 55 would be the casting date, perhaps? that would make it late 55 which would be right for a 56 model year engine.

 

so when ordering parts what year and displacement should I use

 

1956 chevy truck 235.

 

does any of that tell what kind of transmission i have

 

Yes, the X suffix is for standard shift. Trucks were available with hydramatic but that would have the XG suffix, not just X. No powerglide available in trucks back then.

 

so to hijack my own thread...can I attach an automatic transmission to this engine without an adapter? If so, which one would be best. Thans so much Jim

 

You can attach a cast iron powerglide from a 6 cylinder car to it. Or you can attach a 4 speed iron case Hydramatic from a truck to it. That's about all that will bolt up without an adapter. Those are 1950s transmissions, and are kind of hard to find parts for and people willing to work on them.

 

The only automatics that will bolt up to the back of a 235 without an adapter are the '50-62 car 235 Powerglide (V8 powerglide will not work), or if you can find one, a Hydromatic from a '54-62 truck, or a '51?-59 GMC with an L6. Make sure you get everything with it, not just the transmission itself.

What are you putting this engine into? open or enclosed driveshaft setup?

 

i'm going to put in an open driveshaft setup. That's what I get for being excited about listening to other "people". "They" said that a turbo 400 would "bolt right up to the back of a 1955 and later 235".

 

As is so often the case, "they" are full of shit. The pattern on the rear of the block is the same for all 1937-62 216, 235, and 261 sixes. You'll have to buy or make an adapter kit to bolt any modern automatic to it.

 

"they" don't have tools, don't read books and have no practical experience. "They" sit around the cracker barrels and think because a buddy owned a car, "they" have some intimate knowledge of automotive paraphernalia and ancillary information. "They" are known as dorks, dimwits, TITheads, ne'er-do-wells, drugstore cowboys, and dickweeds. The HAMB is your answer, put no false experts before it.

when i bought the engine, the tranny was attached and there was no linkage attached at the side on the 2 rods that stick out. Is there a kit to mount to the top of the tranny to use in conjunction with the clutch?

 

I was looking on nationalchevyassociation and they have a floor 3 speed shifter for 1953. Does anyone know who makes one for the 1956 235?

 

I'm looking on old car manual but I can't find anything about the transmission and the likage set up. Any help?

 

That's the three speed that came in '56 Chevy cars and trucks, manufactured by Muncie.

 

I just found the numbers on the tranny...D6 56 GM 7 8307195 T
what information does this give, being as I cant decipher all that stuff on the net.
