I finally got my '88 vert out of storage. I'm going to repull the engine. I don't think I did the swap right the first time I tried (too little experience, too much frustration, too little patience.) I know I have stuff wired wrong, because when I have it key on engine off, the oil pressure is halfway up the gauge and the coolant temp bottoms out?? So I'm going to retrace all the wires and double check that I've actually got the ECU repinned correctly. In the meantime I'm going to rebuild the extra engine I've got laying around and paint it up nice and pretty.
