Here’s my take on “needing” to use .904 lobe designs in Mopars.
Most of the Mopar faithful believe their pride and joy is superior to the Ford and a Chevy offerings.
Is the only thing that makes them better the use of a .904 lifter??
Cuz....... there sure are a **** ton of good running Chevies out there that seem to be getting it done with cams that function just fine with .842 lifters.
I figure...... if they work good in a Chevy, Pontiac, Buick, Ford....... no reason they wouldn’t work at least as good in a Mopar.
Are there instances where using a lobe design for .904 lifters will really pay off? Sure.
But that’s not every single build.
