06 Daytona and 09 Challenger R/T's. No lifter tick.

AmsOil 0-20 in the Charger due to MDS shutdown and 0-30 in the Challenger tracpac. The Challenger had a tick in it until the tires were properly smoldered and the rev limiter bumped a few times.

No mods except shock-tower brace. Drain and top off the trans with a good synthetic if you don't have the service history. 5.7's are sweet throttle and 24.5 highway.
