What i have for sale is a pair of Venturi Cluster booster insert's.The Rochester 2-jet carb has super restrictive inserts in the venturi cluster boosters for street driving.When you race with the 2-jet you need to replace this with a new pair. These inserts have the center bored out to 1/4" witch is the max alloud by IMCA for thr Hobby Stocks.You cant just get out a drill and turn the 1/16" hole into a 1/4" hole,it just dont work.those of you that have tried it know what i mean.Take it from those of us who  have done it,JUST BUY these and install them.It is best to use a epoxy like jb weld to install the inserts. If you are asked why they are shiny, just say that happened when you debured them after you drilled them out.The cluster in the Photo does not go with auction.will improve performance on all rochester 2bbl,2 bbl,2g,2gv,2gc carbs for all kinds of hi-po uses IMCA,nascar,drag racing, street racing(not recomended),boats with merc i/o on them.These are a cheap horse power gain.
