I have a couple of original issue 97's; these have '67' cast into them which tells they are original issue on 36 commercial vehicles. These original carbs are also stamped with the main jet size. One has .045, the other .046. So, these are how they came from the factory, jetted to suit 221's. You may want to jet up a bit I think?

Yes Brian. My 39 coupe is running a Stromberg 97 jetted at 46.
Its a 221 plus 80 thou. This was checked on a dyno and needed to go from 45 to 46 as little lean at top end.
So with the single 97 at the 258 cu maybe around a 48 but to stick with 65 pv.
Just getting this engine fine tunned. Running NGK 6L and these are looking good at present set up. ie 97 carb jetted 46.
