Love the power my 410 smallblock makes, but the idle is pretty choppy and I'd prefer it be as smooth as possible (kind of a sleeper car). Assuming the carb is set properly, and I believe mechanic has it spot on, are there ways to smooth it out? Adding a vacuum canister (I don't know the proper terminology but I have seen them) that holds vacuum help? The power brakes are fine. The pedal does get a little hard after back to back use, but I can live with that. This engine is in my '89 Diplomat Police car so choppy idle isn't exactly "appropriate". Now if it were a Duster or Demon, etc......

It is a brand new engine so I don't want to change out the cam. Just wondering if there is a simpler solution that might lessen the choppiness. Thanks.
