i am sure there is a painless wireing kit among tons of other fuel injection kits its a 350 they make everything for them, or just take the computer system and harness out of the donor vehicle if it was a fuel injected 350 already but it is way easier to have it carburated and as far as the tranny it will bolt up, the 4.3 tranny will bolt to a 350 considering the 4.3 is the same block minus 2 pistons.
