I run multileaf springs on my 69 SS 396. and they work well. I would check your shocks, and if they are "soft" replace them. I have had good luck with the shocks made by Edelbrock, especially on the heavy front end of my car. At one point I considered installing traction bars on my car, but the spring shop that I go to advised me against it saying that they put adverse stress on the springs. I don't know if that is true, but I left them off and I have no wheel hop and my car sets level.
