injector size for 500+ HP 347?

I was wondering what size injectors to use for an edelbroc vic jr. headed 347 that will make a touch over 500 horse at the flywheel. This motor will probably have a 125-200 shot of juice thrown in also. It is my first build dealing with fuel injection and any suggestions would be greatly appreciated. Also what size throttle body would I need to support this kind of power? The motor is going in a 86 mercury capri.

wet shot or dry shot. wet shot i would use a 42 pund injector dry shot i would use something a little bigger. do you have this stuff already? im selling my 347 600 hp all motor pump gas and streetable. interested? it uses vic jr. heads and i will part it out.

I would use 42lb injectors and a wet kit.
