Hard Starting Hot Big Block

Just to update this thread as people are engaged (thank you all for ideas and thoughts). I'm going through and adding the ford starter relay as mentioned early and noticed the riv-nut I used as my ground in the trunk was loose! So while I was grounding up front by the motor I'm sure the "chassis" ground I had in the back was subpar. I have a new riv-nut tool since the time I installed that one and was able to get it nice and tight. Going to wrap up the ford starter relay now.
