Slant Six Exhaust Mannyfold
Here is a great comparison for you RRR
1972 Duster Slant 6 on left, small pipe.
1976 D100 Slant 6 on the right, 2" flange opening with 1 7/8" OD pipe.
Thinking the later 6 manifolds are going to have a better bigger exit.
ebay has used later model ones for 100.00. Think the trucks are going to be best.
Side note: 1976 Dodge D100/D150 225 /6 had the best factory cam for performance of all the slant 6s made. So you would think that manifold would breath better too.
Manifolds can easily be turned upside down, use an end milling machine and open up the exit to the full 2 inches.
Good Going on the Slant 6 Build.
