I see you are Dot to Dot on your timing gear line up at 6:00 o'clock on the cam gear and 12:00 o" clock on the crank gear.
You are going to want to roll it over until your cam gear is at 12:00 o'clock and your crank gear is at 12:00 o'clock so when you drop in your distributor it will fire at top dead center on compression stroke on #1. You line up the 2 dots with a 12" ruler straight edge.
Right now at dot to dot, 6 cam to 12 crank . . You are 180° off for dropping in the distributor, it will be firing TDC on cylinder #6.
That is just the way it works on the mopar small blocks.
