Buick 300 bellhousing, clutch assembly

Mike, those look like 1967 valve covers, I have '67 340 covers on my '66 Special with 300. Painted my 300 red to match the car.
I also added the aluminum '64 4bbl intake manifold. I found the intake at a swap meet for $35 15+ years ago. The cast iron 300 4 bbl intakes are hard to find and might be $200-300!

Both Offenhauser an O'Brian Truckers make finned aluminum valve covers that'll fit. They're listed for the Buick 215:

Late model Rover V8 valve covers will fit too. 'LowFlyLark' on V8Buick used them in his build..... there's a pic somewhere in his 13 page build thread:

Here's a pic of the 300 in my '66 Special. I'm happy with it's performance, especially with a 5 speed behind it.

I have an extra 65 300 if you just want to build it to your specs. It ran good when I pulled it. The last one we did had an aluminum aftermarket intake , but I do not remember the manufacturer. That extra 300 is complete,it still has the engine harness on it. They are a pretty light engine.

I have no problem with the performance of a 300 I just want to dress up the engine with aluminum intake, 4 bbl, headers and maybe some different valve covers. So what I need to do is find the letters that determine the year. If it is a '67 are there aluminum intakes for that engine?

You may be able to narrow it down by crossing the charted casting numbers on the intake, heads and exhaust manifolds with the numbers on yours.   Buick only made a 4 bbl manifold for the 300 in 64 and 65.  These were on the only high compression 300s made. The 64 was aluminum and matched the aluminum one year only heads.  The 65 manifold was iron and matched the iron heads used from 65-67.  The runners are smaller on the aluminum manifold and are a restriction to the iron heads. 

The 340 came out in 66 and was available in 67.  These were available as a high compression engine in those years. This left the 300 as a base model 2 bbl low compression engine in those years.

The 300 motor will have the last eight digits of the vin number of the vehicle they came out of, on the front of the motor just below the drivers side head. The first digit is the year.

Thanks I will look again but I didn't see any numbers there. I will clean it again and see if something shows up this weekend

Thanks again

7H114739 on the front of the block so it is a '67 300 ?

^ Correct.  7=1967, H=Flint MI assembly plant, XXX,XXX=car serial number
