Therefore, neither will have to lean on their combo, which is the same in both cars, to secure that all important round win! So they just race each other in bracket mode and continue on with the same factor. Allen, is that a good explanation???

And yet, when it's convenient for them, the manufacturers "manipulate" the weights and NHRA goes right along with them! Case-in-point,

2019 Challenger 1320 #3399 8.23 a nice natural A car that can make AA/A/B

2017 Challenger Hellcat #4500 7.50 natural AA car that can make A

Same car, #1100 difference between the two? It couldn't just be that Mopar was picking-and-choosing classes could it?

Larry, maybe you could ask your Mopar buddys about this (and your hood) and I'll find out about that .525 FFFFord cam.

The Hellcat is one of those combinations that I will be shocked if anyone actually builds one!!

Billy the .525 cam is the 427/425 the .527/.527 is the mystery cam not listed in AMA sheets for the 428/360/335 engine.
