I have a stock L24 72 240z datsun. What carbs would be on it? I can take a picture if there is any question. What would be good for me. I want a little better performance, but I really want to stay on the cheap side of things for this car. What should I be looking into?

sounds like you should already have what you want. send a pic if you want, but just go to www.ztherapy.com to learn about "roundtop" SU carbs. The video is worth every penny. Learn to tune what you have, they're plenty till you really change your block/cam etc (even then, they are quite good, IMO)

good luck, Jeremiah
