The basic problem is trying to make electrons go all over the place and through a bunch of connections before they are needed for work at the starter motor. The system works much better if you can create a short, direct path from battery, through relay, to starter. I wrote a plan for the smallblock. Your wiring design is likely very similar. YMMV.
