Just for the record....the motor torn down at the Indy Nationals was a 1969 375/396 in a 1969 Camaro(not a 1970 402). Everything was found to be legal except for the piston weight, which was 28 grams light. At the end of that season NHRA changed the rule to a piston/rod assembly weight, which would have made the aforementioned engine legal.
