yes I misread your post sorry. but I'll stand by this "The 09 challenger will run very low 13s bone stock" It will not ... maybe the SRT-8. Stock 5.7 Challengers run 13.80's at best. Hey I like my 5.7 in my Magnum R/T AWD. It's a great motor and I almost have the 4700lb sled in the 13's but not a chance I'd try that swap.
