If the cam has a lot of duration it might need a lighter piston spring. what you can do is remove the pri. rods and spring and put in 5 steps leaner pri. jets 67's?, then put just the piston back in.See if that don't clean it up. If it does either nip a coil,or get a lighter PP spring. Most S/SS cars run this way,(without rods).I wouldn't drive it on the street with no rods though.You can also check if the bottom well plugs aren't leaking. gsa612
