I think tat would be advertised.  Old school numbers :)
Generally IIRC, about 280-285 is where the idle gets ugly and low end starts

"For a 4-cylinder engine, once you start getting close to 300 degrees
duration, it becomes marginally streetable. The stock SU cam is 256 degrees;
the Solex cam is 280 degrees.

Hey Gordon, is that at .050" lift?  1mm?

(BMW does it at .5mm, I think, and it gives numbers that make
the hotrodders (.050") cringe...)
