For the stock Carbs on a 1971 240z?

Those may not be exactly what I would get, but I am just looking around. Any ideas are welcome. I dont care if I dont get any extra power out of it, but do you think that I might and possibly how much?

Whenever I get a triple carb kit, I will still use these for that and just buy one more of these and stick them on.

For the first thing you ask, well, I've seen a lot of people run those on the stock carbs. Some say you gain power, others say they don't notice any difference so I really couldn't say not having much experience with carbs. To answer the second question: That would be okay if you plan to run triple S.U.'s. But to go from twin S.U.'s to triple Webers/Mikunis etc., you have to buy three new air cleaners.

The stock air cleaner has tuned air horns installed in them . You will loose performance with the aftermarket air filters . They do look cool and sound good.:surprised
