it does show you how adaptable these v8's are though.
the girdle is there because a cam with 700 thou of lift does pretty bad things to the valetrain.
there are hundreds of basic mods done to these engines in race applications,and my engine is pretty basic at 500hp.
you should see the trick stuff they put into pro stock engines.400 cubic inches and over 1000 hp at 11000rpm!not bad for a basic 50 year old design engine hey?not bad for a comprimised engine.
Everything in the quote above is absolutely true, although I wonder why a basic 500hp engine needs 700thou of valve lift. Two points come to mind.
1. The Chrysler V8 was already five years old when the Chevalay came into being & by the early 70's was being overwound in the traps with their huge stroker cranks to 10,000rpm which wasn't too shabby for a huge dinosour engine that was designed in the 40's.
Many of the mods that are required on the Chevrolet are simply not required on the Chrysler.
2. In all fairness, I am not comparing apples to apples here. Chryslers design brief was to design the very best engine that could be devised with the technology of the time & cost [& weight] was no object. The Chrysler New Yorker was never a cheap car for the masses & there were no bean counters looking over the design engineers shoulders.
The GM design team brief was to come up a small, light efficient & much more cost effective engine. To this end, they succeeded beyond their wildest dreams as this was truly an engine for the masses.
That both engines have carved out for themselves legendary status for different reasons is a testament to the engineers that toiled over their blueprints & the companies that had faith in their abilities.
But I'm a Mopar man & Chevies suck, Nar nar na nar-nar
