ok here we go ! I am looking for a 650 cfm holley double pumper or vaccum secondary carb for my, being rebuilt 340/.040 over engine. I'm told the existing 3353-5 780 cfm is overfueling , or will be on the new engine. it will work but is too big ! So anyone got one to sell or want to swap ?
I have a 650 CFM Holley double pumper spread bore carb. It worked very well when it was on my 340. I have not used the carb in 30 plus years, so it will require a new gasket and rebuild kit. I will sell it for $50 if you are interested.
