I would research and add up all your power needs. Keep in mind, you wont be running everything all the time. Elect fans and EFI would be your continuous draw items, along with lighting concidering you may be driving at night. Not sure what your stereo needs might be.

Elect fan and EFI will be the biggest draws. Using LEDs everywhere helps with lessening the power draw there.

I plan on a 6 speaker setup with a hidden audio setup. Basically its just a 4 channel amp box that plugs into a phone or mp3 player as the head unit. Dual 3.5s with bass blockers in the center dash opening, 4x6 in the kick panels and 6x9s in the rear deck. No amp. Car is a radio delete, so i want to keep it looking that way. Going to run flowmaster 40s to quiet it down. Should sound ok. So i can hear my tunes.

I am going carbureted, and mechanical clutch fan so my amp draw needs are less than yours. An 18" mechanically driven clutch fan with a proper shroud cools just as good as proper sized elect fans along with not having to run additional wiring, relays etc.

However I do recommend running a relay setup for your headlamps. This takes the strain off the stock wiring, and will allow you to run halogen sealed beams and have them burn brighter instead of going with more expensive HIDs.

I got a nice relay box setup i plan on using made by littlefuse. Its a sealed box, uses micro relays. And GM weatherpak terminals. Picked it up off evilbay. Its just taped in place. Car is in the mock up stage. I will be wiring it up, then pulling everything out for paint. I think it looks like it belongs right where i have it mounted.
