Ram horn manifold
If anyone was wondering what size bolts to get for the OEM 350 exhaust manifold, the thread size is 3/16 24 and the middle size is 2 3/4. I found this through trial and error and I only found ONE bolt this size between Lowes, O'reilly, Napa, and Advance auto parts. I have lots of 3", so I'm going to have to cut them down. Apparently no one wants to run the original manifold anymore.
