1970 Dodge Dart 318 upgrades

all of the above cams take about the same number of degrees difference between .008 and .004 23-26 degrees
the gotcha is on the close side
The 440 cam takes 29 degrees to go from .004 to .050 (Crane's intensity) but takes 41 degrees to go from 50 to .004
The cams are asymetrical with the factory cams having long closing ramps- and really long closing ramps on the exhaust
hopes this helps on your dynamic compression efforts- which are appreciated and interesting
