camshaft for mild 340

the 214-224 is 50 years old and the Cam Dynamics> Crane Summit- if that is what they use is almost that old
Obsolete as in you can do much better today
power difference may be small but torque is much better
I've used lots of the 204-214 and 214-224 back in the day but not now
yep key word is MILD
I can run 10 degrees shorter with a MOPAR cam with the same pull
