Treblig's doughnut?

R3dplanet said

Hey, I've ditched my headers and installed some 1971-1972 exhaust manifolds on my '65 Barracuda with a 360.

The passenger side is casting number 3618623 and fits fine. The center dumps looks reasonably straight forward to access in order to make a head pipe. The driver side casting is 3614368-2 and also fits fine, barely missing the steering column, but it's in there. The dump points slightly forward so it needs a head pipe or adapter with a pretty sharp 180 bend.

Thanks,

I have TTI headers on my 65 Barracuda now, but ran 340 manifolds for many years - first a pair of 72 manifolds, then later a pair of 68-70 hi-po manifolds.

On the passenger side with a 71-later center dump A body 340 manifold, a factory Duster 340 exhaust pipe will fit as is except you'll need to add an inch or so to the pipe after the first bend to the rear before it drops down.

On the driver's side, I have a 4 speed so there was no pipe clearance between the torsion bar and the motor. Instead, I ran the exhaust almost straight down and ran it between the torsion bar and the driver's side frame rail. There's one spot there where there's room for a 2 1/4 inch pipe to go through without rattling. From there, just run it back to the muffler. Sounds funky, but I never had a problem with it.
