Well the final numbers are in for my flat tappet 10:1 451” stock appearing engine. It will be retired following a run of 11.63 @ 119.09. Traction wasn’t the best and it 60’d at 1.77 and the DA was over 1200. I am more than happy with what I was able to get from a very mellow build. It nearly matched the numbers of the fastest “383” builds ever.
I’m just a few weeks I’ll be pulling the 451 and replacing it with the 499” 13.7:1 roller cammed build. My original goal was to go 11.4-11.3 at 120 but with all I learned from racing the little engine I may have to revise my expectations.

I’ll keep all posted

Bill
