Any wideband kit will work with carbed cars as well as EFI. If you want one with built in logging there is DynoJet, Zeitronix, and Innovate(if you get RPM converter).
Innovate LM-2 has a built in converter for RPM but I heard it sucks. The LM1 works good though and alot of carbed guys that run those as well. I saw ALOT of the muscle cars running in the F.A.S.T class with LM1's.
