How to get rid of understeer in a 1970 340

Reasonable , under 1000.00 , preferably 3 or 4 hundred ?

Go add an adjustable rear sway bar from Hellwig. It will change that understeer real fast.

Do you have a stock front sway bar? Adding a 1 1/8 front will help the front grip by not rolling over so much.
