TSP Cathedral 3/4 Race Camshaft – LS 5.7L / 6.0L w/ Cathedral Heads

The TSP Cathedral 3/4 Race Cam is a modern throwback to the old-school small block 3/4 race cams — reimagined for cathedral-port LS engines. Built for 5.7L and 6.0L combinations, this cam delivers hard-hitting mid-range power, a deep choppy idle, and +75 HP gains over stock in real-world dyno testing.

Camshaft Specifications:

  • Duration @ .050” (Intake/Exhaust): 232° / 240°
  • Lift (Intake/Exhaust): .629" / .615"
  • LSA: 110°
  • ICL: 109° (110+1)
  • Powerband: Aggressive mid-range and top-end
  • Estimated Gain: Around +75 HP over stock

Required Components:

  • Valve Springs: .650"+ rated dual valve springs required
  • Pushrods: 5/16" hardened pushrods required
  • Stall Converter: 3200+ stall torque converter required for automatics

Dyno Proven:

Tested on a 10:1 compression 370 CID LQ4 using stock 317 cathedral heads and a TBSS/NNBS intake manifold, this cam picked up an impressive +75 HP over stock. Expect strong gains with a wide powerband and that signature lopey idle.

Sound & Drivability:

  • Idle: Aggressive, choppy, classic race cam feel
  • Drivability: Streetable with proper tuning and converter
  • Ideal Use: Weekend warriors, street/strip builds, retro-inspired power

If you're running cathedral heads and want an LS cam that hits like an old-school small block, the TSP Cathedral 3/4 Race Cam is your go-to for chop, torque, and tire-frying performance.
