Exactly..... the bonus of doing a top swap as apposed to a SS M90 kit, is that all series II/III supercharged 3800 mods are compatible with your engine, the only difference between the L67 and the L36 once it is top swapped is the pistons and rods, so all fuel rails, ported mainfolds and various other mods that cannot fit on the SS M90 kit can be used if you top swap.......
P.S. I spent less on the whole top of an L67 (heads up, including Supercharger, TB and sensors) than ZZP charges for their fuel rails
