Hard Starting Hot Big Block

Ring end gap to tight?
Tight thrust bearing ?
Tight starter to flywheel alignment?

Loosen the starter and move it away from the flywheel . Sometimes those starters have a large hole on one end


Defective starter?

Runs great once fired up, temps get to 210 and fall to 190-210 seeming regardless of the situation I've put it in so far. Have about 100-150 miles on the motor

First starter was a generic mini for a 93 Dakota then moved to the MSD DynaForce. No changes to how it cranked hot or cold.
