I assume your going for an all stock restoration, right? Have you checked the wrecking yards for a replacement manifold? I know the 390 is few and rare but, the 360ci. has the dog leg exhaust manifolds I think are the same as the 390 and are still around. they can be found in 70's AMC's and jeeps made before mopar bought them out. If not a stock resto, I can recommend Doug thorley (I think the spelling is right) long tube/tuned hedders. They are based in LA Cal. I built and raced a 71 Javelin for 2 yrs. and the biggest bang for the buck improvement was the headers I put on. I could really feel the gain in the "seat of the pants" over every other performance part I put on the engine. Any other info you need on the engine just e-mail me and I'll be happy to help! SQZBOX
