Im doing the same swap, I have a LT1 with elderbrock preformer heads and cam, I have not startd doing the sweap yet but i was wondering how hard was your wiring harness. did you run into probelms, and are you using teh ECM from the 87 or a ECM for a LT1? I have a ECM out of a 97 z28 and was gonna ust that....thansk for any info you can help me with, Im in San antonio.....

the swap is easy the only hard thing to do is drilling a new hole for the passanger motor mount. i got the wire harness from currentperformance.com they made me a closed loop system that connects the ecm to the motor and allows it to run with out any major wireing just connect 3 wires crank signal, 12 volt power on run and start and the fuel pump wire. it cost me $550 but they can make one for you if you have an old harness for about $375. as for the programming i found some software for sale called lt1 edit, and i am going to buy that. if the motor is a 97 than it will work but if it is not than you have to program that ecm
