R H 59,thanks for the reply!You are steering me in the right direction.I'm going to go with your suggestion of a R.V.type cam kit for now.With the iron 68 manifold all I need is a 67 q-jet.I'll look for one at the next swap meet.The rams head style exhaust manifold on the 283 is 3747038 '64-'68 283/327.Do you think I could use the stock exhaust for now until I can afford a matched dual exhaust kit?or should I look stock manifolds with better flow.I'm leaning toward keeping the original look all around and making some more power.The car is 100% original maybe I'm nuts but it feels wrong to change it.
