A friend of mine is doing a ls swap on a 68 2 wheel drive , any pros and cons on headers for this swap ?

LSx Swap forum

General consensus on no fuss manifolds is Trailblazer SS.

Headers you can make fit, but top of the heap and made for our application are the

Doug Thorley swap headers. Also the schoenfelds seem to be gaining traction.

Here

Only cons that I can fathom the expense of the big boys or modification of some close enough models. Otherwise these motors love a free flowing exhaust.

I used stock trailblaxer ss manifolds cleared everything

I used 2010 Camaro manifolds. I like that the exit straight down instead of angled backward.

I tried to use stock '98 F body manifolds that are sometimes recommended... no go for me. I used a set of block huggers. They fit great and I didnt have to deal with an EGR block off. I'd probably go Pacesetter TBSS headers if I replace them

There was a forum piece on this website, that had a group buy on the Doug Thorley headers. I have a set in my basement, but have not installed any yet.

How about a little more info on what motor mounts/stands/frame position were used.

I see a lot of header threads but limited info on the setup which could make or break a certain combo......

I used Pacesetter Coated Long tube LS1 header and I am pleased.

The engine was installed with the tubular CCP motor mounts, but the POL mounts would also work. The Doug Thorley headers were designed for just this truck frame and the LS engine combination

I ended up with the ece/dirty dingo mounts and headmen husler mid length headers.
1 3/4. with 3' collectors, no frame mods needed.
