I would hate to go back to the HEAVY cast iron stock manifold. ...and I've said it before and I'll say it again. The factory iron dual quad manifold has the SAME single plane design as the Weiand (I have put them side by side) and no one has said that one has a velocity problem. In fact Ma Mopar must have thought is was good since they put it on their cars. It looks to me like Weiand just turned the factory dual quad into an aluminum single 4 barrel. I know my 318 really starts to pull when the RPMs come up, but I think that is also a function of the cam. Does anyone have any hard data on the manifolds?

I just don't think that Polys have the velocity for a single plane. Earl, have you tried a 4 hole spacer on the Weiand? This often picks up a little low end by making the runners a bit longer and improves signal to the carb. The taller the better. Just a thought....Joe [AD removed for archives] ------------------------------------------------------------------- Are you serious about buying a NEW car or truck soon?
