leaf springs work great, if you you use a good slapper bar or calvert traction bar. I run in the 10s with a SBC in my 67 nova and never had a problem (I use 14 inch slicks) Am switching to John Calverts traction bars and his two piece mono leaf springs (He will make them custom length for you and custom spring rate to raise or lower the back of your car. Only real disadvantage of leaf springs is that they weigh a good bit more than a coil spring rear suspension, bu that extra weight helps traction in alot of cars that need the weight over the tires. Attn Sir shredalot; Alotr of guys make the rear chassis out of 1 5/8 round tubing ( a good quality steel) and it works just fine and the real good news is that you can bend it in a bender, very easily and custom fit it by trying the fit and bending until it fits. Global west suspensions in california (
WWW.globalwest.net) makes alot of their subframe connectors with the 15/8 tubing. check them out, they are a real good company for suspension parts Chevy Art
