Engine and Vin # Decode Help

I need a little help in deciphering this cars #s.
Vin # 164679C043566
Engine block # 3932388
Head #'s 3932441
Engine Suffix Code #T0904HV

After hours of research the only thing I can tell is that this is a 1969 Impala Convertible V8 with either a 302, 327, or 350.

The Year One website says that since the engine doesnt have a VIN # next to the Suffix #, the engine was not installed on a chassis on an assembly line.

The HV suffix said the block was for a 1965 327/350hp Vette?
Chevrolet Engine Suffix Codes

This is the info I have on the heads.
3932441 1969-70 350 intake 1.94 stroke1.5 cc76.26

And to throw me off even more, I have 327 side markers!!!

All help is greatly appreciated in telling me what I have sitting in my engine bay.

The 3932388 was a 1969 only casting used for 302s and 350s not 327s. It has 4 bolt mains, the only way it came. I suspect what you're reading as an HV suffix is really either HU or HY. HU is 255 horse 4 bbl used only in B bodies. HY is 300 horse 4 bbl used only in B bodies. The difference between them mostly is the cam timing. Given the big chamber 441 head which is year and application appropriate, I'd say you're looking at an upper power level but not high performance 350. The lack of the VIN being stamped on the engine might say this is a dealer installation, perhaps a warranty replacement or the engine has been rebuilt including a block decking that took the serial number off.

Your VIN says it's a 1969 Impala or Caprice, made in L.A.

And i almost forgot. The T= Tonawanda New York / 09= September 04= 4th day.
So that means it was from Tonawanda New York on September 4th.
The rest you need to re-check and make darn sure what the last two letters are. It's real easy to miss read the codes.JMO

I think I got the 327 info from a Camaro site. Here are #pics. If you tell me that isnt an HV I'm going straight to the eye doctor.

I got a PM telling me I may get better info over here than the Impala forum.

Thanks for that verification Cole. Now so what does the suffix code and engine block # tell me? I'm still lost.

Well here's what the block and heads above tell us.
And the suffix code T0904HV say's it's a 1965 corvette 350 HP 327. T= Tonawanda New York / 09= September 04= 4th day HV=1965 Corvette 350 HP 327.
That's what i get anyway. Sounds to me like you have a good one there.

So what would be the determining factor in telling what it actually is? I have never had a motor confuse me the way this one has...the only thing I am pretty sure on is that since the partial VIN isnt by the suffix, it is not the original motor.

That's what i am leaning to also. Maybe someone else will chime in and shead some light on this for you. I was also wondering if maybe the block was a left over like a replacement block that was just sitting there and they put it in your car but i really don't know. If you think about it mortec has the block as a 69 model block and the suffix is from a 65 vette. But i am sure someone on here will know.JMO
It's got to be one of the two IMHO. Wish i could be of more help.
