Or so I’ve heard.

By 1970 the game had changed with Pontiac offering the 340 hp 400 4-barrel engines with the small-valve #16 heads in the Le Mans and I would suppose the Tempest as well no matter how many doors they had.

Yes, 1970 saw the XV code 330 hp 400 4-bbl (small valve #16 heads) replace the 1969 350 HO in all non-GTO A-body styles and the XX code 265 hp 400 2-bbl (small valve #11 heads) available along with the 350 2-bbl engine. I have a Tempest 2-dr coupe with the XV 330 hp 400 4-bbl and a Tempest 4-dr sedan with the XX code 400 2-bbl.
