From the start running this in a heavy vehicle (durango dex210F) the motor was incredibly powerful. I was shocked how much speed I could get from the motor out of the box using recommended timing (50 degrees). Motor performed well enough that another fast driver picked up the motor and enjoyed it as much as I do.
I typically gear this thing around 3.6 FDR and 58 timing on the can for onroad Stock Touring. Motor runs very cool and comes off around 140 degrees at these settings. Amazing motor for sure!
