UPDATE

My 318 turned out to be in good shape to just do a cam swap. I ended up trading the milled out J heads for some Non milled J heads with bigger valves. I am hoping here in the next few days to finally fire this thing up. I just have a few questions to ask prior to firing. Full motor info......
78 318 with J heads that have larger valves, purple shaft 284/484 cam, Eddie carb(1406 number is on it, idk cfm), Torker II intake, Hooker headers(El cheapos), otherwise all stock from there.

1. I Installed a Holley Blue electric fuel pump. What should I set the fuel pressure to to start with? I installed 3/8" fuel line also.

2. Good base point for timing? Stock electronic ignition.
