⏱️ Valve Timing Events @ .050" Lift

107° LSA (ICL 104°)

• Intake Opens: 12.5° BTDC

• Intake Closes: 34.5° ABDC

• Exhaust Opens: 45.5° BBDC

• Exhaust Closes: 1.5° ATDC

• Overlap: 14°

 

108° LSA (ICL 105°)

• Intake Opens: 11.5° BTDC

• Intake Closes: 35.5° ABDC

• Exhaust Opens: 44.5° BBDC

• Exhaust Closes: 2.5° ATDC

• Overlap: 13°

 

110° LSA (ICL 107°)

• Intake Opens: 10.5° BTDC

• Intake Closes: 36.5° ABDC

• Exhaust Opens: 43.5° BBDC

• Exhaust Closes: 3.5° ATDC

• Overlap: 14°

 

112° LSA (ICL 109°)

• Exhaust Opens: 41.5° BBDC

• Exhaust Closes: 5.5° ATDC

• Overlap: 10°

🧮 All events calculated at .050" tappet lift. Overlap represents the period near TDC where both valves are open, influencing scavenging, idle, and sound characteristics.

 

🚀 Performance Highlights

 

Standard 110° LSA: Delivers the perfect street/strip balance — strong torque, crisp throttle, and that signature mid-lope idle.

 

107° Option: Tightest separation, producing maximum chop, increased midrange torque, and the nastiest idle note.

 

108° Option: Slightly broader torque curve with still-aggressive idle and quicker throttle response.

 

112° Option: Smoothest vacuum and idle quality with excellent street manners for automatic applications.

 

Ideal for naturally aspirated or mild nitrous setups up to 150 HP shot.

 

Works best with ported LS6 heads, long-tube headers, and free-flowing intake/exhaust.

 

ECU tuning required to fully realize performance potential.

 

 

 

🛠 Recommended Valve Train & Torque Converter Upgrades

 

Valve Train Setup

Valve Springs: Dual or beehive hydraulic roller spring set rated for .600"+ lift

 

Seat Pressure: 150–160 lbs @ installed height

 

Open Pressure: 400–420 lbs @ .600" lift

 

Coil Bind Clearance: .060"–.080" minimum (target ~.090")

 

Retainers: Tool-steel or titanium

 

Pushrods: 5/16" or 3/8" Chromoly, one-piece (7.400-7.500”)

 

Lifters: LS7 or equivalent high-performance hydraulic roller

 

Rocker Arms: Factory 1.7:1 with trunnion upgrade kit recommended

 

Install Notes: Always verify piston-to-valve and retainer-to-seal clearance during degreeing

 

 

 

Torque Converter / Drivetrain Match

Automatic (street/strip): 2,600–3,400 RPM stall (tight for daily, higher for drag)

 

Automatic (107°–108° LSA): 3,200–3,600 RPM stall for more aggressive response

 

Manual Transmission: Lightweight flywheel and high-clamp clutch for sharp engagement

 

Recommended Gearing: 3.73+ for best acceleration and power delivery

 

ECU tuning required for idle, fueling, and spark optimization
