What RPM going through the traps with a 408?

Mmmmmm…I trap ~6800 with mine (4.10 gear w/ 28” tire) in the ¼, but I run 1/8 mile most of the time. You have a little bigger cam than me and a bigger carb (the rest is about the same), but you’re a little slower…Have you spent much time tuning the carb? If not, there is probably a tenth or 2 right there.

Good luck with the 10 second hunt. I got mine to run 6.93 this spring in the cool air, but in the heat it runs 7.08 most of the time.
