Part # 1022051 – Stage 5 Turbo Camshaft


This Camshaft must be installed with new rocker arms. LC Engineering will not warranty any camshaft that was not purchased together with Aluminum rocker arms. LC Engineering highly recommends using our Pro Camshaft Kit (Part# 1020000) or Double Spring & Retainer Kit (Part# 1023210) when running any cam with over .460" lift or in any application that requires a sustained RPM of 6,000 or higher.


The following figures taken @ .050 lift at valve with .000 valve lash.


Installation Notes:

  • Always check valve to piston clearance and Valve to valve clearance with this Camshaft! Failure to install this cam with matched valve train components can cause engine damage.

  • After installing a new camshaft, lash #1 intake valve to zero then screw intake valve in .080” (Valves not closing completely) with spark plugs removed turn engine over CAREFULLY BY HAND. Do intakes first, if OK then do exhaust. If engine cycles without binding, you are sure that you have minimum clearance (If binding occurs, piston clearance is required).

Camshaft Break-In Instructions

The first few minutes on camshaft and rockers are the most important wear period. In this period the cam and rockers become burnished together. When installing the camshaft, thoroughly coat the lobes with the special assembly lube provided. Cam should be installed per factory service manual procedures. Set valves at proper lash dimensions, and then readjust valves after break in period is completed. CHECK valve train for interference. CHECK valve to piston clearance, you must have .100" min. CHECK valve spring retainer to valve guide and seal for clearance. CHECK valve springs for coil binding, you must have .090" min. Of free travel before the springs become solid after the valve in fully open. 98% of all cam failure is excessive valve spring pressure.

Start engine quickly, excessive cranking of engine is not good for the camshaft. Bring rpm to 1500-1800 for 20-30 minutes (ABSOLUTELY NO IDLING & NO REVVING OVER 2000 RPM) during the break in period. Camshaft should now be burnished to the rockers. It is absolutely vital that once a cam lobe and rocker have been burnished together, they remain together. So if the camshaft and rockers are removed from the engine, be sure the rockers are numbered and reinstalled on the same lobe. Failure to do this is asking for disaster.

NOTE: Standard degreeing procedures should be followed for maximum performance. All cam specifications are checked at .050" lift.
