I have looked all day for what kind of headers they used for a ls swap. so here is my question I have a 94 3/4 ton that I have dropped a 5.3 into with the original 3 speed manual with granny and od (yea a 5 speed) so I have painfully figured out (I have back surgery 5 months ago) that I cant use the manifolds that where on it. So I am wanting to know what is the best headers that any one was able to use that the only required labor to put them on was to bolt them on. thanks

 

schoenfeld ls swap headers may work. Contact them and ask.

 

well they say that there is one that will work i guess I shall find out....

 

I have hear people have used the sanderson headers as well.
schoenfeld seems to have a good rep too!

Have you looked at any of the threads in this section??? Classic Trucks - PerformanceTrucks.net Forums

Some of the build Threads have lots of info. Dirty Dingo seems to be popular for motor mount kits and AC swap stuff when doing conversions on the older trucks.

 

Im installing a dirty dingo R4 a/c kit this weekend and im running Josh Powers adapter plates with 350 clam shell mounts with schoenfeld headers
