Ihra question

What class would a 1969 Camaro run with a 454 crate motor?

Same rules as usual. Shipping weight of the car divided by the IHRA rating of the engine used = natural class, and can then go up or down one class. I don't have the numbers in front of me to tell you exact numbers/classes.

Also, the crate motor must be on the IHRA approved list.

There's an approved 454 crate motor that's rated at 425 HP, similar to an A/Stocker.
At 8.00 lbs per HP, the car without driver would weigh 3400, and 3570 with driver, and it will fall in D/CM.
