I have been looking for a 1965 Caprice for years that I can afford with the 409, very rare, and first year for the Caprice and my favorite body style. My neighbor had one in New Orleans, one of the few I have ever seen. Dave

There was an ad for a tri power setup, air cleaner, and heads for $1500
 
Engine choices included the inline six-cylinder as well as the famous Chevy small-block and big-block V8s. Automatic transmission buyers were given the option of the newly introduced three-range Turbo Hydra-Matic for the newly introduced Mark IV big-block engine, displacing 396 cubic inches. The old 409-cubic-inch (6.7 L) "W" engine was discontinued early in the 1965 model year, so early-production '65s got the 409, available only in four-barrel 340 and 400 horsepower options. The new 396 Turbo Jet V8 was the first General Motors engine to receive the Rochester Quadra-Jet four-barrel carburetor that would become a mainstay until the early 1980s. The new 396 was available as a 325-horsepower version with 10.25 to 1 compression ratio and hydraulic lifters or a high-performance version with 11 to 1 compression ratio, solid lifters and 425 horsepower.

You have to keep in mind that the new models were released in September of the previous year back in the day so the 1965 cars started coming out in the showrooms as early as September of 1964, that would give the old 409 a 6 month model run before being phased out for the new 396. Dave

The 396 cubic-inch engine was introduced in February, to replace the outdated 409 cubic-inch engine, which was only available in 340 and 400 horsepower versions this year — the Tri-Power was gone. By mid-year 1965, the W-series engine would be a thing of the past. During the final year of 409 cubic-inch engine availability, just 742 of the 400 horsepower versions were sold, and 2,086 of the 340 horsepower engines found their way into 1965 Impalas.
 
Dave already covered the bases on the availability in a '65, so I'll only add that I have seen one in person with the 409, along with complete documentation. Really different, and cool. Too rich for my blood, and a curiosity more than anything, but still neat.
 
That's just a BAD joke.

348's as posted in the other posts are about right for $$$ wise. I bought my '61 CANADIAN Pontiac 4 yrs ago. It had a stroked 348 4bbl motor in it. I purchased a 3X2bbl rebuilt car set-up for $2,200. I sold the motor and 3X2bbls running from my car for $8,800. I have since put in a '64 409 stroked to 474 with 425Hp "690" heads, ported and Edelbrock 2X4's. Motor is low compression (9.2-1) but make some good power. In a 3300lbs '61 Pontiac (not mine) it went 10.32 with 4500 converter T400 and 4.10 gear. So it's supposed to be just over 600Hp as a nothing special OEM style motor.

Honestly, if your piecing one together, look for deals. 333 truck heads were better then most OEM heads unless you got the better 690 heads, then the super rare and pricey Z11 stuff was even more.

I would say, start with a 348 block, BBc rods and either 3.75 or 4.00 stroke crank, THEN buy the pistons. A .030 over with 4.00 stroke is 433 inches. 333 is your best bang for the buck in heads. The 690 heads can be found, but guys want top $$$ for them. I was offered a set of nice, BARE 690's for $2,500. Best heads out are either BWR hi port or the Z12 head by Carl McQuillen. Edelbrock are ok, but these 2 are far superior. As for intake, Carl McQuillin has a nice 2X4 style intake for his heads. And Speedport 6/7000 cast single is good too. Again Edelbrock's are ok, but the other 2 again are far superior.

Prices for this nostalgia stuff is all over the place. I've seen stock stuff for $15K+ just fresh for 425Hp 409's. There is still a market for this stuff as manufacturers are getting more into it for now. But for how long? And to do these are not cheap and has some quirks. They don't rev and Hp per $$$ is not anywhere near that of a BBc. BUT It is cool to show up with an old car, open the hood and see the 2X4's on a 409 and a 4 gear.
 
Here is a nice 1965 SS vert Impala that was sold:

Lots of early 1965's Chevrolets had 409's but the Caprice wasn't introduced until the 396 became available.

I don't know about the Caprice specifically (which was just a trim package on the Impala in that year.) I looked to confirm/deny the 409/Caprice combo but only found the same brochure you posted. But I didn't catch the "Caprice" part of your & Dave's posts. :oops: If the Caprice was a mid-year introduction (I couldn't find a date), that would follow that it was 396 only.

The one I saw was a SS, which technically is its own model and not just a trim package. I'm not sure what in GM's mind constitutes a difference here, as SFAIK the frame and basic body (where there is a direct equivalent, i.e. 2-door coupe to 2-door coupe) are the same between an Impala and a SS.
 
Caprice was a late Feb. introduction, same month the 396 became available.

Trivia, 409 was available for all of 1965 here in Canada as we didnt get the 396 until 1966.

Obviously we didn't get the Caprice until 1966 as well.
