1964 Pontiac Parisienne 283 Frankenstein Motor? Decode help.


Hello everyone,

I recently bought a 283 and Powerglide out of a 1964 Pontiac Parisienne 4-door sedan. I took the motor out of the car this past weekend.  Now that it is out, I have been able to find some numbers and now I am trying to figure out exactly what I have.

The block code on the right front of the motor is 9V184299.  

The block casting number is 3756519.  I could not find a date code on the block.  There is a very faint impression where one would normally find a date code.

The heads are camel hump heads, casting number 3782461 and date codes of A43 and A73.  One of the casting numbers has "11" over top of the numbers "24".

LH exhaust manifold 3846559, and a date code that appears to be 310 or 810 ???

RH exhaust manifold 3747038, and a date code of just a lonely number 6 ?

Intake manifold 3840905, and a date code of 28 ?

Distributor number 1110165 and a date code of 5A29.

Carb is an Autoline rebuild and does not have an original tag on it.

So, it looks like I have a 1958-1962 283 block, but I can't find the date code.   

Heads appear to be matched to each other with same casting numbers, 1964-1966 327 camel humps, but date codes of January 4 and January 7, 1963 ???

LH exhaust manifold 1964-1971 Vette 327-350, date ???.

RH exhaust manifold 1962-1968 full size 283-327 date ???

Intake 1964-1965 passenger car 283 2 barrel, date ???.

Distributor 1965 195 hp and 220 hp 283 full size and Chevelle, dated January 29, 1965. 

Information was sourced from the internet, but as usual, it is basically USA information.

Please advise if there is anything above that I may not have correct, as our Canadian Pontiacs may of course be different than USA cars.

Here are my basic questions.

1. Any place else where one can find the date code besides on the back of the block in the bell housing area, as it is not there? 

2. What does the prefix code 9V stand for and is it year specific?

Any help greatly appreciated.

Regards,

Chris

PS I couldn't get some of the images below rotated correctly.

The Camel hump heads are not original to a '64 Canadian 283 as you probably know, but your '63 head's date codes could originally make it onto a '64 327.

I own a bastardized 283 in a 1964 Custom Sport also ... they are out there.biggrin : https://canadianponcho.activeboard.com/t65190927/mystery-engine/

From past posts I remember that we were able to determine when GM went from the crank case vent tube ( road draft ) to the fitting which vented this to a PCV valve. I just can't remember when it was ( pre 65 ). That is what is shown in one of your pics. This is all per PCV in the valve covers.

The 9v number is one assigned at the GM Canada plant when it was installed in a car, if you go to GM Canada Historic and get their package, that number would be included if this were an original block. You would also get a build sheet on a 64.

Maybe someone thought it would go faster with the bigger heads and are those 2.5 inch exhaust manifolds?

The 9 V may mean a powerglide? The rest of the numbers I think are just sequential numbers stamped in order as each motor is installed in a car, nothing to decode.

That pcv at the back of the block is the same as on my Cdn 62 283, in 62 that was optional instead of the road draft tube , the pcv to the carb base, nothing to valve covers, became stock in 63.

 Yes, those valve covers are '63, '64. The aircleaner is '64.

Back in the 70s I had a summer job working in a garage. On of my jobs was installing a rebuilt 283 into a 65 Impala. The car had a 327, but the owner opted for the 283 short block because it was $20 cheaper than a 327. On went the heads intake and valve covers onto the 283. You may think that the car owner was a cheapskate, but $20 was a good amount of money back in 74. I remember that the door labour rate was $6:50 an hour. I am sure that a lot of stuff like this happened when the economy wasnt going well. Another one that I remember doing was putting a Ford 255 V-8 in an Econoline one ton van. The 255 no one wanted and the auto wreckers had a hard time selling them, they could be bought for half the price of a 302.

Hi all,

To answer a question from above, the exhaust manifolds are regular manifolds; 2" I believe, and not 2.5".

Yes, after 55 years, anything is possible with parts on a motor.

Still wanting to find answers to my 2 questions:

1. Any place else where one can find the date code besides on the back of the block in the bell housing area?

2. What does the prefix code 9V stand for and is it year specific?
