yes you are right my friend's camaro does have a roller cam and Lifters in it...

and i agree on the oil... in my hotrod engines with flat tappet cams.. i used to run rotella T 15w-40 but even rotella T as of late has reduced the ZDDP in their oils...

so i run Valvoline VR-1 20w-50 and also the ZDDPlus additive to it..

my only point about my friend's camaro is that all the engine bearings have survived using 5w-30 oil because that engine is factory built with no doubt tighter clearances than most racing shops will do.. as it is built for the street.. it has a redline of 5200 RPM as opposed to the 7000 RPM that race motors typically carry...

the shop that built PG's engine may have built this engine using looser racing clearances rather than OE clearances..
