hooker aerochamber's anyone?

Ummmm, the 400 could use a little attention to the state of tune. It's not to bad now, but I have not put a 02 sensor on it to find out exactly where it stands.
The 318 Duster has the 1850 Holley on top. I picked up a kit to swap out the metering plate to a 4150 style metering block. I jetted down the OOTB primary jets to a 66 I think, I forgot to honest.

I picked the carb up here and it ran very rich. So into my jet box to find a smaller jet. Didn't happen. So I ordered 3 smaller jets than the smallest I tried and had.

Weird how it seemed to blow alot of white smoke out back. No head gasket leaks or anything. It just sits alot.I put my hand in front of the exhaust and it coated my hand in water and rust. That car needs attention to it's tune. Spring time for that and floor boards.
