I must say i have never had a problem with
a stock starter on a Ford except when they were worn out
Never had a FE Mustang though and there is not often hot around here
Reason i bought a power master was i had no good stock late FE one
But i have had problem with brand new Chevy ministarters on customers cars
they thought they must have a ministarter and bought the cheapest one they
could find because......Hey its so much cheaper to build a Chevy
yeaa its
even cheaper if you ride a bicycle .......
