OK, I currently have a 305 q-jet TA sitting outside. I just picked up a TPI setup off of an 87 TA and going to do a conversion with the motor build to TPI. My question is this. If I buy a Painless wiring harness (or other brand) that is for a speed density setup, get the SD ecm, and get the correct knock sensor, what else would I need to run everything. Would the rest of the factory sensors work the same? I'd have a SD harness and ECM, and sensors off of an 87'.
