🧰 Installation Notes: Use new hydraulic flat tappet lifters (sold separately or available as a cam/lifter kit) Requires ZDDP-rich break-in oil for proper cam and lifter protection Stock or mild performance valve springs are typically sufficient Degreeing the cam during install is strongly recommended for max performance
📦 Product Details: Brand: Redline Cams Grind: Redline 268 Street Performer Cam Type: Hydraulic Flat Tappet
Fitment: Small Block Chevy 262–400 CID
Included: Camshaft only (lifters not included unless specified)
Condition: 100% Brand New Made in the USA
🔧 Lobe Separation Angle (LSA) Options
The standard grind is 107° LSA, but we also offer 106°, 108°, 110°, 112°, and 114° to fine-tune power delivery and drivability.
LSA Characteristics Best For 106° (Standard) Very aggressive, choppy idle, strongest low-end torque and midrange hit. Narrower powerband but very responsive. Street/strip builds, hot rods, and performance-focused small blocks. 107° Slightly smoother than 106° while retaining a lopey idle and strong torque curve. Offers a balance between rowdy street sound and broader drivability. Street performance builds that want attitude without sacrificing too much smoothness. 108° Good balance of torque and top-end power. Idle is still lopey but slightly more manageable than 106/107. Daily-driven street machines with performance in mind. 110° Wider powerband, smoother idle, better vacuum signal for brakes. Sacrifices a little low-end hit for improved mid-to-top range. Street cars with power brakes, highway cruisers. 112° Very smooth idle, excellent street manners, strong top-end. Loses some rowdy idle character. EFI builds, daily drivers, towing setups. 114° Clean idle, broadest RPM range, maximum drivability and computer compatibility. Lowest overlap. Fuel-injected engines, OBD-II friendly, long-distance street cars.
💡 Why Choose the Redline 268?The Redline 268 is a perfect match for the builder who wants real-world performance without going overboard. It’s a mild street cam with excellent throttle response, a noticeable idle, and broad torque you can feel. Drop it in, tune it up, and enjoy a more responsive, cammed-out small block every time you hit the gas.

🔧 INSTALLATION GUIDE
Small Block Chevy V8 – H.F.T. 268 Street Performer Camshaft
⚠️ Before You Begin
-
This camshaft is a Hydraulic Flat Tappet — proper break-in is critical.
-
Always use new lifters with a new camshaft. Never reuse old flat tappet lifters.
-
Use a high-zinc (ZDDP) break-in oil and proper assembly lube.
-
Verify your valvetrain geometry, valve spring pressure, and coil bind clearance before installation.
-
Recommended supporting mods: upgraded valve springs, double roller timing chain, performance intake, headers, and a 2000+ stall converter.
📦 Tools & Supplies Needed
-
Torque wrench
-
Camshaft installation tool (or long bolts in front of cam)
-
Cam degree kit (optional but recommended)
-
Timing cover gasket set
-
Assembly lube & break-in oil
-
New lifters (required)
-
Double roller timing chain set
-
RTV silicone sealant
🛠️ Step-By-Step Installation
1. Preparation
-
Disconnect the battery.
-
Drain coolant and remove radiator for clearance.
-
Remove intake manifold, distributor, water pump, timing cover, and old camshaft/timing set.
-
Carefully remove lifters and keep pushrods organized if reusing.
2. Camshaft Installation
-
Coat cam lobes and journals with assembly lube.
-
Gently slide the new camshaft into the block, supporting its weight to avoid journal/bearing damage.
-
Install new timing set (verify dot-to-dot alignment at TDC).
-
Torque cam sprocket bolts to 20–25 ft-lbs with thread locker.
3. Lifter & Pushrod Installation
-
Coat new lifter bottoms with moly paste assembly lube.
-
Insert lifters into lifter bores.
-
Reinstall pushrods and rocker arms.
4. Valve Adjustment (Hydraulic Flat Tappet)
-
Rotate engine so each cylinder is at TDC compression stroke.
-
For each cylinder, tighten rocker nut until pushrod has zero lash (no vertical movement but still spins).
-
Turn nut an additional 1/2 to 3/4 turn to preload the lifter.
5. Reassembly
-
Reinstall timing cover, water pump, and oil pan (if removed).
-
Install intake manifold with new gaskets and RTV at end rails.
-
Reinstall distributor (initial timing set to ~12–16° BTDC).
-
Refill cooling system and check all connections.
🔥 Camshaft Break-In Procedure
-
Use break-in oil with ZDDP and a primed oiling system and use Zinc oil for the life of the engine.
-
Start engine and immediately raise RPM to 2,000–2,500.
-
Run engine at varying RPM between 2,000–3,000 for 20–30 minutes.
-
Do NOT let engine idle during break-in.
-
After break-in, change oil & filter.
✅ Final Notes
-
Recheck valve lash after break-in.
-
Retorque intake manifold and header bolts after first heat cycle.
-
Recheck ignition timing; fine-tune advance curve for performance.
