well,seeing as a l18 or l20b fills the engine bay, so with an l28,you'd have to mount the radiator on the front of the grille.you could make it fit if you were prepared to cut the firewall & refabricate the firewall & transmission tunnel.by the time you'd got a transmission on the back,you'd have to get the rear passenger to change gears for you.the point of all this frivolity is,no it won't fit without cutting the car.
