  • 🔧 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.
