70 dart 470 ci drag car build.

So, what’s loss from peak power to 6800?
And, that 6800 is about 1000rpm past peak?

Nonetheless, if you’re still making decent power at the rpm point you’ll be seeing at the finish line…..it should run good in the car.
We're making some sonoco 110 tests.
I'll run one out to 6800 for you real quick and post what it says. So far the sonoco is slightly down on power vs av gas.
