Chevy 350 Break-In & First Start Checklist

Break-in isn’t one-size-fits-all — it depends on the cam and components used. This guide covers the universal “don’t skip” steps and keeps you aligned with GOAT’s notes: prime the oiling system, verify fuel/timing, and follow the included instructions for your specific combo.

Before first start First start After start FAQ

Before first start

  • Fill with the correct oil (use break-in oil if recommended for your cam/valvetrain).
  • Prime the oiling system before firing the engine.
  • Confirm fuel delivery and check all fittings for leaks.
  • Static/base timing set so it starts immediately (avoid extended cranking).
  • Cooling system bled, fans working, thermostat/hoses verified.

First start

  • Start and immediately verify oil pressure.
  • Watch temps closely and check for fuel/coolant/oil leaks.
  • Follow the cam/component break-in instructions provided with your engine for RPM/time guidance.
  • Do not “free-rev” a cold fresh engine; bring it to operating temp steadily.

After the first heat cycle

  • Re-check for leaks, clamp tightness, and hose routing.
  • Verify timing and carb tune (final setup matters).
  • Follow your recommended oil/filter change interval after initial run-in.
  • Drive gently at first — vary RPM, avoid sustained high load until fully sorted.
Warranty tip: Keep your paperwork (including your balance sheet) and follow proper installation/startup procedures.

Break-in FAQ

Do I have to prime the oil system?
Yes — always prime the oiling system before first start.
Is there one universal break-in procedure?
No — break-in needs vary by cam/components. Follow the instructions included with your engine and use the correct oil for initial startup.
What else matters most on day one?
Fuel delivery, timing, leak checks, and cooling capacity. Final setup (timing/carb tuning) should be verified during install.
Is this engine “ready to run” without checks?
It’s designed to be drop-in friendly, but you must install it properly, add fluids, verify settings, and confirm vehicle-specific compatibility.
Can overheating/detonation damage a fresh engine?
Yes — improper installation, overheating, detonation, or abuse can cause failures that are not warranty-related. Monitor temps and tune safely.
