Again, I don't want to ruffle feathers--actually IDGAF because that's what's wrong with the world these days is people "biting their tongues other wise known as being PC" --Be careful looking at flow numbers--there is something wrong with his bench and I have mentioned it to him in the past. His numbers @ low lifts do not JIVE whatsoever. Also to get back to the topic in this thread--porting manifolds. Porting a manifold is FAR more difficult and time consuming. To do it right the manifold really needs to be cut up and welded back together. The good news here is that most manifolds and applications do NOT warrant actual porting. In fact if the manifold is selected and applied properly--hold on to your hats for this---Porting will often produce less power and result in slower acceleration ie.- slower ET's at the track. IMO porting a manifold is warranted when the manifold is grossly undersized (wrong) or it is on a Nth level build looking for that last few HP. J.Rob
