273 exhaust?

Headers may be a bit much for a stock 273. I put 1971 360 exhaust manifolds on my 1970 Dodge Dart with a 318. The engine also has a stock 68 340 intake manifold, also got 2 1/4 inch dual exhaust, heddman x-pipe and flowmaster style mufflers. This added quite a boost in power and sounds awesome! 360 manifolds are cheaper and easier to find than 68-70 340 manifolds. Just make sure the driver side manifold is from an a-body, the passenger side manifold should all be the same. Good luck!! :thumbup:
