Here is a great package for all you horsepower freaks out there. Yet another variation of the monster AIR ATTACK LS7 is now available, the AIR ATTACK LS7 D1SC. We use a D1-SC Procharger to fit under the hood constraints of a Corvette.

We don't install this package here due to emissions constraints. Choose your favorite local tuner, pull the engine and send to Katech, then we send your complete package back to your tuner for installation and tuning.

The package consists of:
Air Attack LS7 engine build

-DLC coated pins
-Callies H-beam rods

You may ask why the dip at 5400rpm. It is tuning related. Since we are not providing a calibration to the customer (it is the responsibility of the tuner) we did not do a comprehensive tune on the engine dyno. The engine dyno test was simply for break-in and power validation.
