Have you thought about going with an overdriver transmission? The swap isnt prohibitively expensive and the benifits make it one of the best modifications you can make to your car. I run 3.73s and a 2600rpm converter and I can cruise at 70mph at 2000rpm all day
Hahahaha... "the rear end man" hahaha... But in all actuality, yes, he is the man to speak to concerning your rear...hahaha I crack me up....
