The 252 TORKER H.F.T. is engineered for explosive low-end torque, snappy throttle response, and street-friendly drivability in your Small Block Chevy 262–400 cid. As a Stage 1 torque-focused camshaft, it’s perfect for mild performance builds, daily drivers, and hot rods that want to feel strong acceleration off the line without sacrificing vacuum or idle quality.
This cam thrives in the 1,200–5,000 RPM range, making it ideal for street performance applications where usable torque and throttle punch matter most.

📊 LSA Options – How They Affect Performance
| LSA | Powerband Behavior | Idle Quality | Vacuum / EFI Compatibility |
|---|---|---|---|
| 106° (Standard) | Hard-hitting torque, fastest throttle response, most aggressive lope | Very rough/lopey | Lowest vacuum – carb builds preferred |
| 107° | Similar to 106 but slightly smoother idle, still torque-biased | Rough | Low vacuum – mild street/strip use |
| 108° | Balanced torque & mid-range, strong street power | Noticeable lope | Usable vacuum – works with power brakes |
| 110° | Broader torque curve, improved drivability | Moderate lope | Better vacuum – street friendly |
| 112° | Softer low-end hit, more mid-range/top-end | Smooth | Good vacuum |
✅ Recommended Upgrades
For best performance with the 252 TORKER H.F.T., we suggest:
New lifters (mandatory with flat tappet cams)
High-zinc (ZDDP) break-in oil & moly cam lube
Performance valve springs & timing set
Long-tube headers & free-flowing dual exhaust
3.08–3.55 gears (street torque curve sweet spot)
High-flow intake manifold & carb/EFI
📌 Installation Notes
Use new lifters – never reuse old ones.
Apply moly assembly lube to cam lobes & lifter bases.
Run 20–30 minutes at 2,000–3,000 RPM for cam break-in.
Use high-zinc break-in oil (mandatory for HFT longevity).
Set ignition timing to 12–16° BTDC as a baseline.
