We ran a V6 Charger with exhaust on it in my buddy's GT2 Cammed SE (L36 car)...and we nosed it from a 30-100 and a 70-120...but the higher the speed the closer it got...I THINK he said we were around 130 and it started to inch away...but like stated...it was the 3.5...the 2.7 is a horrible engine choice.
