does the 3.9 wake up any with long tube headers? also for those running true duel exsaust how/were did you mount 02 censors? thanks for any help

 

Grammar and spelling is a lost art.

 

long tubes for 3.9 don't exist. Only shorties. Mids and Longs are made for the 5.2 and 5.9.

 

my thought is take a set for 5.2 and cut off the tube not needed and cap it off..

 

A whole lot of money for no gain. Spintech Mids are $700+, I can't imagine what a set of longs cost.

I put a touch over 100 HP to the rollers with my 3.9 through an unlocked converter and 4.10 gears. Considering it was rated 140ish at the flywheel I think, I'm considering that not bad. And that's with clutch fan delete, 1.7 roller rockers, and a tune.

 

so not worth the the time then lol.. so far only mods i have is an exsaust from lmc a fan cluch fan delete ...o and it does have a throttle body spacer (previous owner installed) that i been to lazy to find shorter bolts and remove it lol
