I gave you empirical evidence from actual observations from rod testing.And so did another guy after your reply.
Pontiac had dynos,scores of engineers to evaluate carb position on the OHC engine. And these same engineers doing dyno and road testing failed to uncover the premature camshaft wear on these engines that caused excessive warranty claims when they were new.Same GM guys dropped the ball on the Vega engine.
