for efi system i would really look into the new Holley HP efi. kit #550-605 if your proficient at wiring that kit has an unterminated harness that you will have to put ends on etc. yourself.

Fuel system go as big as you can. however, remember that all big electric pumps have huge electric draw. I have had good luck with the magnafuel efi series pumps and also if you don't mind it cranking a revolution or two more the aeromotive belt drive pump is also a great alternative.
