That doesn't answer my question. Lots of guys in here have gone to the small GM starter or an aftermarket high torque starter and they have never had to shorten the wires going to the starter, if fact no one ever mentioned the wire.
Okay. The answer is the wires are much longer than needed. At least 6-8 inches. I ran the wires through split loom from the bulkhead connector down towards the starter. The loom stops about 2" past a factory loom clamp thats attached to a transmission bolt. I tried to stuff the excess wire up into the loom and it was a pain in the *ss. It kept popping the split loom open. Of course I could zip tie it tight or wrap it with tape but not the way I would do things. Its just as easy to cut it at the bulkhead, pull it back where I want it and crimp on a new terminal. I have a stock of Packard 56 and 59 terminals. I also have the crimper used to make factory crimps.
