building an Xy fairmont streeet and strip car on gas(NOS) 409Strokerclevo... C4 auto full manual 4000 stally we expect to have around 550hp at the treads with no gas im thinking of droping one leaf out the rear end and install some caltracks dont have the money for a 4 link any thoughts or ideas on the subject would be good thanx

that and shocks if your strapped for cash ( you will need some traction device ) the c4 will give you trouble maybe and i hope theres not much bog in car as it will come out and crack after the car twists with that much torque
