Rebuild 5.7 or buy something else?

thanks for the input fellers.
Photorep, drive by wire is the electronic gas pedal for the new 3g hemi. They dont' have a throttle cable anymore, its all electric.
Wireharness is the wiring hardness for the new hemi to hook it up. It has to be "hacked" to work outside a factory car, has to be hacked to run on the ECM or have a custom ECM.
the $2000 is the cost from the place that does it, that has a good reputation and its a "plug and play" setup, not much for me to have to do....im lacking in then electronics department sadly.

the new 3g hemis, EFI and computer controlled....no more distributer, carb, or coil boys.
