Hi Pauly,

 

Have a look at www.ztherapy.com they overhaul carbs in the US and have pictures outlining the differences.

Not sure if all the changes appeared in Oz, but it should give you an idea what you're looking at.

thanks for that i also forgot to mention would a single 2barrel carby be better then the double su's

IMO Su's are the go for a standerd, or mildly modded L series motor, don't bother with the single 2barrel, 280zx injection is better than that....

260 carbs were flat topped, while 240's came with round top carbs. the 260's have square mouths, while the 240's had round

thanks for that also wondering will the single 2 barrel affect fuel econemy in a good or bad way

240Z carb's will give better fuel economy and overall performance. Theoretically the 2-barrel can be made to give good economy esp if it's a webber, but the manifold design is pretty crap and economy suffers. If you have a holley the situation will be worse as they are very crude carb's.
