I'm looking for some info and possibly pictures of work done inside of crossrams. I may try playing with the insides of mine some more to get out this bucking / kicking / surging that I get in gear below 1700rpm or so. I may try to reduce the overall plenum volume but still have a crossover inside.

Looking for ideas. Maybe even make an adjustible volume via a slide or something, that I can quickly adjust by removing one carb, adjust, re-install carb.




how is your distributor set up? the advance curve has to be right on for large plenum multi carb apps.
