SA/FB front end aerodynamics. Chin spoiler/Splitter?
 

Converted my 79 SA to a 1/4 mile drag car. The nose is lifting around 160mph and the steering becomes a little sketchy and "light" towards the end fo the 1/4 mile.

I looked around briefly and found several bumper/body kits that appear to be for "looks only". I was looking for a cheap/easy solution for some type of functional air dam up front. (I know cheap and easy don't usually go together). Just wondering if anyone has a made or found some sort of aftermarket "chin spoiler" that fits the SA bumper decently and has helped with "nose lift".

Similar to this maybe...

It appears you may have too much lift on your front suspension. You could lower your front end if you have adjustable coil overs or put some limiting straps on them .
