"High Torque" 415 HP
(Stage 3)
This Chevy 383 stroker has the best of both worlds. A balance of great low end power with enough top end HP to really get things moving.
Our most street friendly stroker package. Works excellent in cars with automatic transmissions, 4x4s and heavier vehicles.
Crisp exhaust note with a nice lope to the idle, while still maintaining good manifold vacuum for power brakes and accessories.
This engine is our highest selling performance package, and for good reason.
