After telling him to go to the B-body site for correct answers you continue answering him 4 times in 4 posts. Why would you send a member elsewhere? As Trump would say. Your fired! LOL
The 2bbl and 4bbl pistons are the same.The 4 bbl commando had a hotter cam and 4bbl intake only. Except for the 66 super commando had high compression irregular domed pistons. All pistons are available at Egge's . Flat top with valve reliefs for 2bbl and commando 273, Or irregular domed for the super commando. The irregular domed pistons are cheaper. The Domed pistons really improve performance on these little engines . But headers and larger carburetor are recommended. advertised @ 275 HP verses the 235 HP out of the commando. Get that @ FBBO LOL
