The carb I bought refurbered but I have no idea on the jets/springs or any of it. I plan on getting a secondary spring kit and have a jet kit sitting here waiting for some testing. If the jets are stock I understand I should go a little smaller on them no?

I have a 2400 stall in there now, I know down the road I need to go larger. I am running an 8" rear. I'm not planning on blasting down the dragstrip too often, I just want to be able to hit the gas hard and not bog.
