I'm having a hard time picking a header for mw ls1, right now its stock but more mods later. I'm seeing primary tube length should be at 32 inches plus or minus 1 inch. Also different headers for different engines 346, 382,422. Wow I'm confused. Then add to it all the manufactures. SLP, FLP, MAC, hooker,ASM,dynatech, TTS. I don't have to worry about emmisions because my ls1 is in an early model car, do I still need to run o2 sensors and if so I want the headers to have provisions for this. Can any body give some input.

 

What type of other mods do you have now, what do you plan to do with the car as far as mods? Do you have a 346, are you going to build a 382, do you spray a lot of nitrous or have a supercharger? Manual or auto tranny?

 

Its a stock ls1 in a 66 nova. 4l60e trans, not really any plans for nitrous,want to do a good heads and cam package as soon as it gets broke in probably only has 25 miles on it.Havent done anything else yet no pulleys,no hpp3 etc.

 

i absolutely LOVE my Dynatech headers! they sound great and look even better

 

Sounds like you'd probably be best to custom fab them to fit your car and clear the steering shaft then. There might be an Fbody or Corvette header that would fit though, but who knows...
