6.0 & 2wd 4l80e into OBS: Header Questions
 

I am almost done doing everything I can before I actually try to fit it all in.

I was going to order the Schoenfield Conversion Headers....
But then I read b/c I am going 2wd instead of 4wd...I can use NBS headers...

My truck was orignally 4wd but I ditched the transfer case and front drive shaft.

What is the best Long tube header out there for a decent price?

Do you have the torison bars still in there?

yes, I still have the torsion bars in there.

I test fit a set of 99-06 headers on my 89 with the 5.3 in it. Wouldnt work. They hit the frame before they would even sit flat on the head.

You might be able to use a 4th gen F body header.

shoenfelds are the only ones i have found

Thanks ordered the schoenfelds and sending them off to get coated thanks!

Check out this thread

Their work is top notch! Just can't justify spending 1k in headers. They make non-conversion headers for the OBS, work of art and out of my price range. Thanks for the link.

Well today is Friday aka pay day and I can't find the *uckers!

I only came across there 2wd models! YELP!

any have access to a wiring diagram for the ls swap to 411 PCM?

They only make 2wd ones. If you take the front diff out you should be ok.
