Long mani for mid range vs free flowing for top end. Just can't fathom all those bends not killing everything

Interestingly they used to make sidedraught adapters for the downdraught manifolds. On my white RS they had two race setups - 48 DCOE's on the "S" bend manifold for the shorter, twistier tracks and 48 IDF's on the downdraught manifold for the longer, more open tracks.[/quote]

Yes you would think so. But then again, the other limitations were that you ran a standard head (with 44/38 valves but NO porting) and 10:1 compression, so they all used to hit a wall at around 170hp. That being the case the manifold was probably not the lowest common denominator in terms of limiting performance.
