Anyone using a P4452782AE on 340/360?

smaller at .050 but ,much longer seat to seat duration which is what counts
.050 is only useful as a rough gauge and setting the cam timing
engine does not start to make compression till the intake is fully closed which is what counts
many aftermarket camgrinders list the mopar specs but others use SAE and publish .050
others advertised "blueprinted" etc and then you see teh same profile for both big block and small block!
does look like a stock 340
BVVC of some hot rod cam grinders that advertise "our version of"
no idea what they are
