Hello Mopar friends, I’m wondering what headers will fit on a 67 barracuda with a 318 with no modifications, I was told Doug headers would & are there different ones for 273,340&360? I’m still kinda new to all the differences and imagine different heads would probably use different headers, thanks for helping me learn this stuff in advance!
There is a benefit(s) to headers. Even on a stock 318 2bbl. Some disadvantages too. Some are personal preferences. Here is a list of some reasons someone might make this swap:
Much easier to run your own dual exhaust at home. They make a lot of header back kits that can be cheap. Also, very easy if you choose to dump before the rear end.
Performance - I did an ACTUAL TEST at the drag strip. I picked up 2.5 tenths and 2 mph in my van (stock 318 2bbl) in only the 1/8 mile.
Sound. Some like the deep throaty sound.
Looks. Many think they look cooler than stock manifolds.
I suggest buying a quality set (TTI or Dougs) and use a mini starter if you do make the swap.
