Answer:
I’m having trouble deciphering what the punched out holes mean on my NHRA chassis tag. The car that I purchased is a 1969 Nova that has a roll cage like you see in the NHRA Rulebook and it also has a funny car cage installed. The blue/silver NHRA chassis tag is punched out 8.50 & Slower and at the bottom N/A. Along the left side punched out 16 and along the top 7. What does it all mean?
Answer:
The punched out dates along the left side and the top show that your car passed NHRA Chassis inspection in the 7th month (July) of 2016 and would expire in three years on July 31, 2019. The punch out of 8.50 & Slower and the N/A shows that it meets the NHRA full-bodied spec that you see in the NHRA Rulebook. The funny car cage by it self does not let your car run under 8.50 in the 1/4-mile. The SFI 25.4 or 25.5 spec for E.T. of 8.49 down to 7.50 does require a funny car cage and numerous other chassis items before you can upgrade to either of those SFI specs.
