Is it fair to say that the vast majority of the mods required in your swap from the LS3 to the LS9 were necessitated by the supercharger and its related components? It seems to me, a Pantera owner could install a dry sump LS7 for about half the cost of a Ford based equivalent. By "equivalent" I mean HP, TQ, weight, dry sump and EFI. In 2006, Hot Rod Magazine did an LS7 dyno test and found they could increase the engine's HP to 600 @ 6,800 RPM with only a cam and exhaust change.

In addition, if you wanted to mount the engine lower in the chassis, you guys now have that all figured out too. It seems pretty "bolt-in" without the complication of the supercharger.


For the most part. The fuel tank/fuel sump we did for better performance during track driving to ensure the engine doesn't get starved for fuel plus better weight distribution front to back. The only system that was done solely because of the supercharger was the intercooler system. Other than that, almost all changes would have been necessary for an LS7 swap as well (dry sump oil system, lowering the motor, moving the motor and trans back a couple of inches, airbox, etc.) because it is much better to leave the manifold in it's stock orientation and run the intake through the front.

The LS7 is a beast of a motor for sure. It was definitely a consideration when we were doing the original LS3 swap, but for this project, we wanted to go with the "cool" factor with the supercharger and get the biggest (in performance), & baddest motor. Wink
