Computer Question

i recently talked in person with hot wire,,they do not supply S&P wiring any longer,,different topic,,,

they told me if runing a non computer trans,the 5.7 comuter will have to be re configured to run the engine with out seeing the trans,,


if the computer has security key,(, not a alarm),,they have not been able to crack that code or convert it yet,,but they are working on it,

seems the more i read on this topic,,the more confusing it gets,,no one seems to know or tell all,,, i want to do a 5.7 completely stock motor swap in to my street rod,,but seems the simpelest way is using a complete donor vehicle,,but those truck trannys ive heard are giant in size,
