Looks like a great build...
My car is almost idenical to yours for the exception of the motor... I have a CSX block.
A few obsevations and advice that you can ignor if you want LOL.
1) The mechanical Smith speedo I have had issues with the plastic gear wearing out. I would do the electronic version of the smiths speedo as the Tremmic tranny has an output for this.
2) I strongly recomend using an ARP
oil shaft, its a weak link in an FE
3) I have had issues with te carter mech fuel pump and have had great results with the edelbrock.
4) I have had a Tilton superstarter for 14 years with zero issues, its a nicer unit that the Powermaster, more money though.
5) do the heater!!!!!! easy to install now but a majot PITA later and its only $250
