I'm running a set of modified tbi long tubes, so is @Dropped88this gets discussed every so often. Summit has headers listed for TBI trucks (88-94) but you would need to add a bung for o2 sensors. Currently no one is here running a set of those that we know.
There are also some mid length JBA's available.
Long tubes, for a Vortec 7.4 - 4WD - gmt400?They exist. I have a set from Patriot.
Good luck finding any for a reasonable price...
I rejected your assumption....Long tubes, for a Vortec 7.4 - 4WD - gmt400?
