First time down the track

Don’t view it as piling on at all. Appreciate all the help. I already have a spring and bushing kit to recurve my MSD pro billet dist cause even thought that’s not the whole issue it’s probably part of it. I have flowmaster 40s through 2.5” exhaust. I am running a 750 cfm Holley so that may be hurting too. And info is welcome and appreciated.
The carb is not hurting too much....my mid 10 second 410 stroker used a 750 dp...just sayn.
