Its probably too lean. See if your tuner cant go to the track with you and log a pass or two. No tellin what the issue is without some data.

You need a wide band. If I were you I would buy a cheep computer and a wideband and log. For 400.00 you can find out what your car is doing. I love terms like loading up. You have no idea if it is lean or rich.

I agree on the wideband. With that type of setup it would be worth the money. BTW - I bet it's till one bad *** machine... my buddy is looking for a 70-72 Z to build up with a SBC 350, something simple as a daily driver.
