Mopar Cam- how many more degrees @.006 to equal at .200?
reversion lots of things, the ones you mention
backcut on the valves, reverse flow, header suck, rod length/ ratio, overlap
my pet peve is that most cams are designed for the short rod sbc where the piston timing at TDC is short
vs the MOPARs where it is relatively longer
sbc starts to pull the piston down quicker so you have to get started on the intake opening earlier
doing the same Thing with a MOPAR allows more time for reversion
same on the ex close
on the other end SBC is rreal slow around BDC so it is not nearly so important whenyou open the ex or close the intake
The post 67 MOPAR cams are VERY aymetrical but for different reasons than modern performance cams-- warranty and wear and smog
