Hello,
Just getting finished up on 383 break-in on 67 Dart.
Did two 2000-2500 rpm pulls bringing water temp up to 150 then cool.
Thing is probably only have about 15 min runtime so far.This time drained water and oil while hot. Surprised at what the oil looks like already.

Hello,
I would like to thank everyone's input on this subject.
I agree with the consensus the isky's are the best choice.
And am grateful that John offered them to me for sale.
Am the proud owner of a set.
Now my next dilemma will be my first break-in on a solid tappet cam?
Any suggestions...
I agree with the confusion about mild rv cam (typically a hydraulic set up) and solid lifter cam.
I, being a rookie in this game purchased stamped rockers/shafts/hold downs before I discovered
the solid lifters and cupped push rods in the valley pan, Duhh!
Now I have valvetrain for my next one...
