88dangerdan Posted May 17, 2014 Share Posted May 17, 2014 I've recently ( 4 months ago ) purchased a early 260z ( 12/73 ) and it has round top SU CARBS. My question is are these what came with the car when manufactured. reason I'm asking is because I just purchased another 260z ( 6/74 ), not that I needed it but I couldn't pass up on the deal, and it has dual Webbers. So I was wondering which one is correct. Thanks Daniel in Stockton Ca. Quote Link to comment Share on other sites More sharing options...
rags Posted May 17, 2014 Share Posted May 17, 2014 (edited) Neither car has the carbs that came on the car when it was delivered. The original carbs can be identified by having a bell design but the top of the bell is flat as opposed to round like the carbs on your first 260Z. Also, the bowl is incorporated into the body of the carb on the originals as being off to the side of the round tops. Although there are many more differences, those 2 are the most obvious.

88dangerdan Posted May 17, 2014 Author Share Posted May 17, 2014 So what I've read the round tops seem to more desirable over the flat tops. but if I decide to get it back in its original state, I would need to get flat tops. thanks again Daniel in Stockton Ca.
