Need help identifying 1965 Riviera engine thanks

Recommended Posts

Could use help  figuring out which engine my 1965 Riviera has (just purchased)

 

Am sure it's a 401or 425 as the numbers on drivers side of block match VIN plate

 

The heads casting numbers are 119614  also indicating 401 or 425

 

Not sure what to make of the numbers on the passenger side of block, per pics it's L followed by a gap then X117

 

Thanks!

Mark

Mark,

 

 Hopefully you have two carbs sitting on top. The LX indicates a 1965 425 cubic inch engine with 2 4 barrel carbs. You probably have a Gran Sport or one of the rare non GS cars with this engine.  Pictures of the car please!

Congratulations, you have the most desirable combo for a 1965 Buick; a numbers-matching dual quad 425!

They only made 454 non-GS Rivs with the dual quad set up in 1965 unless you have an actual GS.

Thanks for the feedback as am definitely not an expert on this, some more pics enclosed

 

Took picture of transmission tag which has a BT code

 

If engine had dual fours etc they are long gone

Nice looking Riviera!

 

For what it's worth, my '65 LX, non GS, has the BT trans too.

 

The BT trans was what was used in the '65s ordered with the 425, whether a LW or LX, unless it was a GS of course.

So, it’s one of 454 non-Gran Sport dual-quad equipped cars. An early production, I would guess around 12A, first week of December

If it is one of the 454 non-GS cars equipped with the LX engine, what happened to the dual four barrel carbs and finned aluminum covers.  Is the stamped number on the tag around the distributor shaft legible?

Next time am over at the storage place will look for this tag ( have a feeling several good bits sold long ago, the only thing the last owners knew is "thought it was maybe a buick engine, didn't think it was a chev engine" )

Thanks

Judging by the posters on the wall, the egg crate grille sniffed its way back to familiar surroundings!

Hi Mark,

 

Congratulations on your new '65 Riviera! 

 

Your car came from the factory with the Super Wildcat 425 cu.in. dual-four barrel engine.  This was a $182 factory option, code A-8.

 

Although your car is not a Gran Sport, it is even rarer, because while 3,354 Gran Sports were built, only 454 came with option A-8 installed.

 

Any chance you could post a photo of the Body Plate on the firewall? 

 

What more do you know about the history of your Riviera?

 

Welcome to the group!

Thanks for your note, will take data plate pic when can get back over to storage place in couple weeks 

No history except bought it from a local couple who were very nice but had no clue about Rivieras except they saw one in the movie Roadhouse and liked it. They bought it at local collector car auction without really understanding much about collector cars

You are a very lucky man..........you should be playing the Powerball lotto. Odds of buying a numbers matching LX 425 65 Riviera when the seller

doesn't know what he has is about one in 300 million!

So Tom, in this case was it made on the 177th day of the ‘65 production cycle?

Hi Mark,

 

In case you're interested, here's a decode of your Riviera's body plate:

 

Date built: First week of December 1964

BODY - assembly sequence number = 48,752nd Buick built for the 1965 model year

ST - Style 1965 Riviera 2dr coupe

FB - Flint manufacturing plant

TR - Trim code 601 - Blue vinyl standard interior

PAINT - DD - Astro Blue (note the meaning of the STAR after the paint code remains a mystery!)

Options: 

E - Tinted glass, all windows

X - Power windows

T - 4 way power driver's seat

S - Remote trunk release

2R - Rear seat speaker

3T - Rear center arm rest

4F - Remote control mirror (driver's side)

5K - Door guard mouldings

5G - Rear seat belts

 

Note that not all options installed on your Riviera are coded on the firewall body plate.  Fischer Body only coded those options that were installed in the body back of the firewall (inside the car) prior to the body being mated to the engine/chassis on the assembly line. This means options like Cruise control, Guide-Matic, 4-note horns, etc. could have been factory installed on your car, but these won't appear coded on the body plate.

 

Probably the rarest option in your Riviera are the rear seat belts.  Very few were so equipped.  I don't have the percentage here, but it's well under 5%. Any chance you could take a photo of the rear seat belts?  I don't think I've ever seen a factory installed set on a '63-'65 Riviera!

Wow thanks for all the info, very interesting!

Can send seatbelt pics tomorrow, noticed previously they look a slightly different color than the front belts(?), can't remember seeing a rear center arm rest, will take pic of area also

Seems like the outside color still very similar to the original which is nice and am happy the engine matches the car
