Well, I guess if the old road tests don't hold much weight, I would place the validity of the Pure Stocks races FAR lower when looking at how these cars originally stacked up to each other. The mega-buck, professionally built, flyweight rotating assembly cars we see today, with scienced-out suspensions and hundreds of hours of dyno time, are a far cry from how these cars ran in their day.
The differences between the 70 RAIII and 70 455 are marginal at best. Minor head differences (same flow, different cc's, similar compression), 068 cam (on M/T 455), same intake, etc. For my money, I'll go with the 55 extra cubes and more torque of the 455.
For pure power at the Pure Stocks, I'd go with a Studebaker.
