A camshaft essay.
The cams install retarded because they are ground on a retarded ICL...This is how they are ordered by Inertia, PWR and Mod Muscle etc...
The cam blanks are actually designed to go in a on an earlier ICL..(eg 106- 108 etc)....but the re-sellers know this will cause P-V clash.
It has nothing to do with the factory timing set or how you degree it - they are simply ground retarded.
Redfish - As stated - this is the ONLY way they can supply a cam with more duration and not cause piston to valve clash with stock pistons.
Like I say..no one is criticising them..they are working between a rock and a hard place...but don't kid yourselves these sticks are generating optimum output....they are not.
