Looking for more 408 pull at the big end?

so....our 410 in our 71 Dart has run a best of 10.38 @ 127 here in Vegas air....shifting a 6500 rpm and running it out the back door at 6900 rpm....

So you are saying we should shift no higher then 5800 rpm...and it will run faster?

in the desert we dont get to see cows....

dam....new converter cost me 1300 bucks....and it will flash to 5400....going to be some fast shifting...and probably need change dana 60 to 3.54 gears......the money i could have saved by running this thread.
