I need help with this engine numbers I posted it in another web site and all I got was sarcasm please help me I need help decoding it.
Let me start  with that it was installed in a 1963 impala SS 4 spd car back in 1974 by the original owner  and it was given to his son in 1982 and last registered in 1984.. His son then left it in PA in a storage garage and was sold to the guy I bought it from
He told me he didn't do anything to the car and that the engine was original so I took the numbers down and I tried to decode them but it makes no sense bcuz this engine has been in the car to my knowledge since 1974 and if I'm correct in those years they weren't stamping engines so if u guys can help me please decode this engine for me please thanxxx
These are the deck numbers
19N556777
V1203MO
Casting is
3932386
Date casting is
K198
I took the oil pan off and verified it is a four bolt main so that puts it into either 350 or 302 but I thought the 350 didn't have them in four bolt main but I might be wrong please help me with this ill be waiting for your replies thanxx

3932388    1969    302    290            4           Z-28 Camaro Rare?-NO! See FAQ on site

suffix (MO)
Code     Year    CID    HP    BBL    Appl
MO    1968    302    290    4    m/t,4 spd
MO    1967    302    290    4    Spec. High Perf. 4-speed


but i gonna tell you the same thing most will, post pics of stamp pad, and casting numbers off the block and crank, you already have the oil pan off, so it shouldn't be a problem.  the  K198 i would think is to late for a 68 302 since the DZ was already available.

The partial VIN you have listed is for a '69 Camaro, the casting number of the block was only used in '69, and the casting date of the block is K198, which is Nov. 18, 1968, so we know this engine is for a '69 model year car. Remember that the model years started production in August rather than Jan 1st, so there were a lot of '69 cars actually built in '68. The MO assembly code was used for the '67 and '68 302, but was never used for a  '69. Post some pictures so we can have a look at what you've got.

 Your post in Team Camaro was honestly answered with the same information you just got here. There was no sarcasm in the replies, unless you took something wrong. This site and Team Camaro work closely together and have many members that use both sites. We strive for accurate information and when strange stories surface, folks tend to dive deep into them to figure out the truth about a car. The numbers AND PHOTOS of the numbers, as requested several times in Team Camaro and here, will bring out the 'facts' about your engine. Be patient, reply with what folks request and the truth will be known.

The cast date of the block aligns with the sequence number for a late November early December build. But unless it's a 427, I don't see how it could have an MO suffix. Mistakes happened, but it seems very unlikely that late into production that that suffix would be stamped on a small block.

I'm glad u can help but is this motor worth keeping?? I was going to put it in a 1968 camaro SS clone I have but if I can find the real car it belongs to I will give it up for a LS motor just to keep the original car with its motor as long as there's proof that the car is suppose to have this motor I am willing to give it to any hardcore Chevy man like me that strives on making sure these cars survive the next generation!!
I'm a 45 year old hardcore Chevy man that's had many collector cars including N all original JL8 car that I made a big mistake selling but I didn't know anything about it so it went
That being said I didn't want to make the same mistake with this rare engine and give it to some kid for his 76 Monte Carlo ..
Help me get this engine to the right owner like I said all I want is to make sure its the real deal b4 I give it up thanxx

Also remember that this engine was in this car since 1974  so the numbers are real and I didn't make a mistake writing them but I am cleaning the engine and taking detail pics of it and if u guys find the car it belongs to or someone that's missing a 302 I'm willing to give it up no questions
I've seen in my years that GM has made big mistakes in castings so this might be the case!!
I wish I knew more about these cars before I made the mistake I made 6 years ago when I found a 1969 COPO and traded it for a fully restored 1969 SS .i didn't know why he wanted my car soo bad he told me it was bcuz he wanted a factory drk green camaro  and didn't want to paint his light blue SS so me like a dummy went for it
I went to his shop and he has the body siting on a huge shelf talking about very high numbers and that I would never get it back

Casting is 3932386

It can't be a 427 with a 3932386 casting number.

Hey Saints, if you want to find anything out you gotta give dude. No one want's to know more about the engine you have than we do, but you keep dodging the requests. On the Team Camaro website you say you want answers without the sarcasm, but you keep setting your self up for it. Help us help you and we all can go on with our business. Just my 2 cents worth.

Hey Cheli, what makes you so sure there was an 'MO' in 69? Curiosity is getting the best of me here. What about you guys?
