need help on motor swap
 

i have a 98 chevy, with a good drivetrain, frame is shot. i found another frame its a 92 i would like to use the 92 cab, i am going to have to use the front clip off the 98 and put on the 92, i know that the motor in the 92 was a throttle body motor. and the 98 is a fuel injection. has anybody done anything like this before? if so any tips or tricks on the wiring?
