David,
It’s clear,that without Studebaker,Pierce-Arrow wouldn’t have had
the money to develope/produce the straight eight.Development must
have been collaborative as the end products had interchangeable
components(some)and yet were not the same.The P-A block was poured
in a South Bend foundary of harder material and the rest of the
manufacturing was in Buffalo to the highest of standards.
Studebaker went on to break scores of records with their straight
eight.Ab Jenkins drove to set some of the score of records
Studebaker set in 1929.
Hydraullic lifters first came out Nov. ’32 on 1933 models.I own
a 1934 P-A 836A with non-hydraullic lifters.This was done as a
cost-cutting maneuver to compete in a lower price bracket.You
could buy a Pierce for about the same price as a Chrysler
Airflow Custom Imperial(their mid sized offering)or a Buick
98C convertible phaeton(top of the line).Very good condition
price today is $70K for the Buick,$136K for the Chrysler(they
made 106 of them)and $66K for the Pierce(500 ’34s,300 ’35s
est.).
I don’t know about the drilled crankshaft,but my 1912 Marmon
32 has one.Also attempts at hydrallic lifters go back to the
earliest times of the twentieth century. Tony Costa
