maximize shift points

gearing ...converter flash ...tire diameter?

looking at your dyno sheet 12.0 to 1 compression..and Champion RC12YC plugs...need a colder plug...

generally you need to go thru a shift loop...trial and error is the only way to figure out where to shift at...

I run a Dana 60 with 4.10 gears. I run a 27" tire at the track and I have a 3000 rpm stall converter. I am running NGK plugs at this time, but at the dyno it was Champions. I'm not sure of the heat range on the plug right now, I'd have to pull one and look.
