I have a local rebuilder who does starters and alternators for me. On the
smaller frame alternators, he upgrades them from 66 amps to 80 amps,
replaces the bearings, and thread inserts on the aluminum case where the
tensioning brackets bolt in. On the starters, all American made solenoid
parts, field windings, new bushings and brushes. I usually do 6 starters at
a time, 3 standard and 3 high torque.
IF YOUR ENGINE IS STOCK, THERE IS NO NEED FOR A HIGH TORQUE STARTER,
but, if you have a high compression, long cam timed engine, you might. Most
of the time, it is batteries and cables that cause slow cranking when hot.
