What parts of the 273 commando engine are special relative to other small blocks? I know about the forged crank and light rods - looking at parting out a pair of commando engines and want to know what I should keep vs let go to the scrapper
273 special parts

Pistons are high compression. The cam is specific to the HP engines. Of course the dual point distributor, intake, carb, air cleaner, and valve covers. I will add the adjustable rockers and shafts.
1964-1967 were all solid lifter cam engines. In 68 they changed to hydraulic and stamped rockers. 1969 was the last year of the 273.
Didn't know they went through 69.....
The LA318 came out (for the most) in 68 so the 273 wasn't needed.
Thanks all for the responses - got the rockers and dual points distributor off. Don’t think I’ll have time to pull the cams. Are the heads worth saving?
Someone might need them but they aren't anything special. Same heads and any other 273 that year. Shipping kills that deal. Usually more than the heads are worth.
Fixed.
go-fish is trying to contact you but your inbox is full..... @go-fish
Always good to grab those when pulling the rockers and shafts. They are only good for solid lifter cams though. And not all lifters are the same inside dimensions.
Thought the LA teen came out in 67? I know I was surprised to see a 67 Belvedere with a 73 in it.....
Not all got the LA teens when it came out. They started with the big cars from what I have read. Canadian cars used the Poly an extra year as well.
I DM'd him.
Fixed it - thanks. Wouldn’t have figured that out
Thought you might but wanted to do what I did here so maybe go-fish would know how to contact someone....maybe he will also learn not to be 'too specific' in the regular forums lol
We talked about that also.
Interesting, some models had both the 273 and the 318 available. Others just had the 318. For instance, according to my Galen book, Barracuda's didn't get the 273 but got the 318. Probably because the 340 was available in that model in 68. I don't see 273's available in any Coronet's or Chargers but they were available in the Belvedere's and Satellites along with the 318's (including the wagon's but the 273 wasn't available in the sport models like the Sport Satellite unless it was a wagon. 67 was a transition year. Pretty crazy to keep track of. The rarest one listed with a 273 is a 68 Sport Satellite 9 passenger wagon. 393 produced. No transmission breakdown though. .

If factory, they are closed chamber heads and have value. They dont flow "much" but we're a good combo for the Commando motor. Yes there is value, condition dependent.

@Jeebis44 Be sure to look at the pistons to see if they are oversized. You can sell those to someone needing to bore their motor. Someone may want the 920 heads if you sell them cheap enough to make shipping worth it.
As far as availability of 273's in A body cars, we have a numbers matching 69 Dart GT conv that is a 273 car. I've got a set of Race Tech custom flat tops for it, and making plans to use Magnum heads and factory Magnum OBDII fuel injection on it when time comes to fix it. I wanted to make it a one of none 69 Dart Swinger conv....but my wife ain't havin it since it's her car...lol.
