FAQs
Why does the STG4 require flycutting?
The aggressive timing events and limited piston clearance on the L86 platform mean the STG4 must have piston flycutting to ensure safe operation.
Can I run this cam with a stock torque converter?
No. The Stage 4 cam requires a 4000+ RPM stall converter to keep the engine in its optimal powerband.
