i am looking at a 92 pickup with a 302 and c4 transmission swap. as the attached picture shows a very unique header set up,he said that no other type headers are available for this 2wd swap. surely they make something better than this setup.any suggestion on headers.?They are like upswept then they bend down in front of the engine and under to the exhaust.

 

Because of funds I just used stock manifolds off a 68 mustang. Lol very restrictive but I got them for free and they fit perfect.

 

Try a set of 5.0 stock headers you might have to do some fitting but they flow better than cast manifolds.
Also look at Norrthwest offroad for engine swap parts.

 

No pic.

I know the Ford vans have some ultra tight headers/manifolds.

Honestly, the restrictions of a manfold is not going to make much difference. Unless you like to sit on a dyno all the time.
