Irv, are you saying NHRA allowed you to race a car with an engine that did not have clearly defined specifications in the blueprint guide?

How did they expect to properly inspect an engine at tear down if there was no published specification, or even an accepted part number?

The blame for that lays solely at the feet of NHRA.
