Magnum camshaft questions

what rumble and lelo said
are you running a carb and mech fuel pump?
I guess you are since you mention manual fuel pump
if so
there you go
do you have the right front cover for manual pump?
now if you are going to regrind the core you have you will need the adapter
new billets are not cheap and not necessary for a mild build
Cam is already a long snout. Wouldn't need adapter. Less there is something about regrinding I don't know. Never had it done.
