transammatt99-which event if huge are you reffering to ?
If it's the camaro/mustang challenge,in 2008 there was slightly over 250 cars,weather was hot(90s') and sunny,in 2009,because of morning heavy rain,only 103 cars showed up.You never can tell how the event is gonna end up because of weather and people having other committments.
different topic: a 4.10 that was previously 3.42 has an increase of torque of 20% to the rear axles due to torque multiplication. A 3.42 with a 350 ft.lb engine,when 4.10 is used that 350 ft.lb. engine would feel like a 420 ft.lb. engine. depending upon how much boost that LT1 was at,low mph and mid mph they could be very similar but then the higher horse of a boosted LT1 would come into play at high mph.
