I feel I have to jump in here and defend GM's flagship division, IMO the
Cad 500 has a lot to offer, especially the port fuel injected version
available as a option in '75 and '76. the aforementioned is rated at 210
hp. and 400 ft lb @ 2000 RPM.
I have researched the 500 Cad, talked to parts suppliers and GMC owners
with the Cad installed and I am more convinced than ever that this is
the route I will go. The 455/ 403 are fine engines it is just that
attempts to increase power ( for climbing long hills etc.) generally
just increase the power band in the higher RPM range. The Cadillac's 45
extra cubic inches translates to more torque at a lower RPM and by all
reports better gas mileage.
