Well that woudl be nice! I guess I can find a BBD base gasket and compare.

the rochester used on the chevy 2.8 is a vac progressive.

This sounds familiar... I think I looked at these before. The thing with the
webers is tunability. I doubt there's a jet set and books and lore on the
Rochester.

The mechanical progressive weber is a very very nice carb. Had one on the
hornet. Took a while to tune up (I posted about it then) but that was very
straightforward. The adapter was 'clean' inside, a good match to the BBD
base.

If 195.6 2bbl == BBD, that pretty much clinches it.
