Exhaust manifolds for Turbo A Body - 03/16/23 02:11 PM
Is there any exhaust manifolds that can be turned backwards in an A body with a 6.4L? If I understand right the bolt pattern will need to be re-drilled but I am OK with that.
Ideally I want to move forward and work on a turbo 5.7 or 6.4(preferably) combo for my 68 Barracuda over the next year or more.
Thank you for any information.

if not mistaken i think it is one or two holes per side not that crazy to do. my son investigated a few years ago.

Some people have use the jeep srt exhaust manifolds. You will need to redrill the heads and I used the Lisle exhaust manifold bolt fixture drilling them as it helped align all the holes and get proper depth of them. Was simple and easy to do and I am running the hooker log manifolds flipped forwards. Holley makes some of their blackheart headers that would work well for turbos too.

truck manifolds exit almost straight out and would be an option if you drill the 2 holes you need, especially if doing twins. I explored that but for a single turbo in my coronet and then the downpipe down low under the manifold with a oil filter relocation kit and a truck style accessory drive. 4" downpipe was tough though. If you didn't mind wrapping twin downpipes under the K member it'd be easy.

A Guy on Facebook used a set of truck manifolds flipped forward. All he did was weld flanges on the end. But yes I think you have to redrill the center exhaust mount holes. Here is a picture of the turbo/ exhaust mounted in his 71/72 Dodge Dart

What about swapping the heads from side to side? Is that even possible on those motors and heads

they are specific side to side but I'm not sure of all the reasons why
