So you should be in between.
FWIW the 455 on the street even on sticky DOT tires if you hit it in a turn it will break them loose real easy and you can get sideways!

I'm expecting 550-560 Hp. I never hit anything while going through a turn after my friend did and totaled his beautiful '68 Vette 4 speed.
