Wheel Hop

I have a new problem of wheel hop. I searched the forum but didn't really find what I wanted. Just finished the car with new wheels and tires. The car: 69 Dart Swinger 340, 4 speed. Everything is new with Mancini extra heavy duty leafs and stock shocks with extra length for the leafs. Wheel hop is bad. Gears are 3:23, làunch at 3500, cam power band is 3500 to 7000. I know I need more gear but I'm in the country and every where is 15 to 25 miles. The wheels are 17x8 with a summer tire 245x45x17. It is factory diameter at
25.7". This car never wheel hopped until I made this change. Before I was running 255x60x15 at 27.2" tall drag radials. I searched and searched for a softer shock with some added length for the heavy duty leafs. I have a set of new Competition Engineering shocks I could run. I run the car on the street and when launching at 3500 is smokes the tires and does the wheel hop. Any launch lower and it's bog because of the cam and gear ratio. Any help appreciated. Thanks FABO
