Nother dumb question
I have now got two 3.9 inlet assemblies , one has the trumpet base bolts onto the lower manifold , the other they are cast as one assembly , from a performance point of view is one any better than the other.? It takes about a week reasonably solid work to polish up one intake assy , and I dont want to do the wrong one
Thanks

Are you sure?? I've never seen one that is just one piece.

Yeah , your right , some willy hunt has welded it right round the outside and bead blasted it . I havnt seen what the bolt holes are like as I havnt removed the plenum . Huh

Weird!, why bother?!?! Sounds like a lot of effort for no gain!

Chris.

Might the coating just be covering the join? There's no gasket used, so no gap.
