as far as i know, there are no true long tube headers for a 4.3 the long tube increase torque and hp, and the shorties increase hp at the expense of torque. or maybe i have that backwards....

You want more low end go with short headers, more top end with longer headers...

its a trick used by nascar, short headers on the short tracks, for more low end, and longer on the superspeedways, more top end, can be a difference of about 15-20 hp depending on how many inches difference in the length

I'm not to sure about torque....I'm more concerned with my get up and go rather than my pulling power, I have a duramax if I need to pull stuff....but i would assume that headers either way will give you an increase over regular exhaust manifolds

If you end up wanting the Hedmans, I've got a brand new set of long tubes, part# 69400, sitting in the shop that have never been installed. PM me if you're interested.

Shorties - Less weight, better low end torque and some mid with a lil high end.
Long Tubes - SOTP through the WHOLE range. BUT, about twice the weight...hah, maybe not that much, but quite a bit more. Also, LT's usually have less ground clearance. Hope it helps! Sketchy |
