Hey everyone, new member here.

I have a 62 2 dr sedan and am in the process of learning the ways of the Nova. I'm stuck on the engine codes. Trying to find out if the engine is original and or what it is. The casting # is 8921968. The # on the pad by the distributor is F09230K.

Couldn't find the info on novaresource.com, unless I'm just looking in the wrong place.

Thanks for the help.

I only see V8 numbers on that site. My engine is an Inline 6. That much I do know.

Thanks for the response though, I really appreciate it.

I cant believe I stumpted every one on my first post. :D

Casting number 8921968 does not exist but 3921968 does. It is for a 1964-76 230 or 250.

Application code (F09230K):
F = Engine assembly plant; Flint MI
0923 = Assembly date; September 23rd
OK = Application; 194 with 3-speed manual from a 1965-67 Nova

Interesting since the 2 codes conflict with each other. I know "OK" is for a 1965-67 Nova 194 but I'm not 100% sure about the casting number. I'd go back and check the numbers again.

I'm starting to think you might be right about the casting number being 3921968. It's hard to tell. I thought the 3 would look more like the 3 on the Application code. I've included some photos...

Thanks for your help.

I'm at a loss to tell you exactly what you have. The casting number does start with a 3 and that number (according to my sources) is for a 230 or a 250 (same bore, different crank). The casting date (I 3 8) decodes to September 3, 1968. To me, that would be an early production 1969 model year engine.

However, the "OK" in the engine application code was for a 1965-67 Nova 194. If the casting number and date are correct, it can't be a 194 because the 194 engine used a different block with a smaller bore than a 230/250 and there was no 194 engine used in 1969.

If I were to guess I'd say it's a 1969 230 or 250 that has and incorrect application code stamp. The only way to know for sure is to open it up and measure the bore and stroke.
