Hi All,

I have a 1953 3600, but it does not have the original 216ci engine. Rather, the engine is a 235ci. The most I've been able to determine is that the engine is a standard 235 model and was made on Feb. 6th, between 1957 and 1962. Apparently, from 1957 on forward, chevy 235ci engines stopped using serial numbers.

So, how do I determine the actual year of production for this engine? I have the following information from the engine block: Casting # = 3769716, Engine ID = F0206A, and two other strange things cast into the block and located below the Engine ID boss --> They are CON 4 and B52.

Can anybody shine some light on my confusion?

Thank you

There is a machined pad just behind the distributor with a stamped number on it. The letter prefix at the beginning of the stamped number should identify the year of manufacture, and other details about that specific engine. There are several websites available with engine number decoding information, just google "Chevrolet engine numbers".

Better re-check that casting number- - - -you might have a 261 engine instead of a 235. If so, that's a real find! The casting number you list differs one digit from either a 235 or a 261 number.
Jerry

Found it! The Inliners' site lists your casting number as a 60/61 truck 235.

You're right about the serial no.s after '57, they just don't help much in ID'ing your engine. But, I think the B52 marking tells us the story, cast date of Feb 5, 1962.

If that's wrong, someone else will surely set the record straight.

I think that the 3769716 block casting code (235 ci block) was used from 1958-63.

As waldo53 posted, the date casting code is the clincher (1962).

The A code in the serial number denotes it's a Passenger application.

Thanks to all for your help and information!

Looks like the engine block was cast in Flint, Michigan on February 5th, 1960/61/62 (conflicting websites abound) and that its intended role was "Standard" (as designated by the 'A' serial number suffix).

So this little truck rolled along for almost a decade and then had its original 216 replaced by a plain jane 235.

Excellent nostalgia!

Brott,

Where was the casting number 3886848 found? The block casting number reference that I use do not have that number. However, 3836848 is the cylinder head number for most 1956 and later 235 engines. Look at this serial number reference for the FO408J decoding. The engine casting number is on the lower forward passenger's side of the block. The casting date code on the block by the starter is also useful. Look at Tim's great site for more useful information.

Hey all, I'm totally perplexed by this one. A guy is selling what he thinks is a 1952 Chevy 235. The numbers on it are:

N375583DAL
3701887
GM3

I can't find either "3701887" or "375583" on the list of casting numbers at http://www.inliners.org/becks/BCN2.html or http://clubs.hemmings.com/clubsites/chevytalk/GMhistory/cast.html

Any ideas on what these numbers should be telling me? What the heck is this motor?

Best,
Nick
