......Your cam and lifters should be "parkerised". This is a lubericating coating which will protect these parts during break in....If they are not "parkerised" rest assured the manufacturer took a short cut on quality....AFTER...you inspect your cam and lifters, send them off to a quality camgrinder to get them "parkerised". Disassembly of hydrolic lifters is necessary before shipping. A prime source of premature failure is a LACK of valve retainer/ to Valve guide CLEARANCE, inadequate valve springs and tension.(causing the lifter to "bounce"on the cam). Micropolish the outer radus of the lifter, ensuring an absolutely smooth radus from the face of the lifter to well past the "edge". No burrs, no nicks, no dings...just baby ass Smooth edges.
Parkerizing (also called phosphating and phosphatizing) is a method of protecting a steel surface from corrosion and increasing its resistance to wear through the application of an electrochemical phosphate conversion coatingThis is one of the processes that are carried out on our lifters.. Applying this process to camshafts proved not as effective as the process being used on lifters and the break in was much quicker.
I tried parkerizing both the camshaft and lifters and that didn't work at all.
No matter which processes are carried out, good oil is mandatory, especially during the work hardening processes that continue for the first couple thousand miles for most engines.
I'll be sharing some UOA from our oil development program at the end of this week on my forums.. Wait till you see how much of a reduction in wear metals can come from a proper "switch" of lubricants in a back to back test.. Then see the differences between a roller cam engine and a standard flat tappet engine.
But none of this is helping the OP, he probably already knew it.. The 163/86B is a good cam for a 2270 when ground on a 1.065 B/C but it does require dual springs and should be applied with ported heads making a minimum of 190 CFM/ intake with no less than a 70% I/E flow margin. I use that Web grind as a bade for many of our custom cams..
