Hi all. I've been thinking about keeping my standard intake manifold on my 5l VS. I don't want any defects other than being too loud or too low. The engine is getting some mods that I don't want anyone looking into. So I had a bright idea..... Use the standard intake so doing some searching (ive been over this years ago) I found the standard intake is poo and needs tremendous amounts of work to be even reasonable. So I went looking at extursion honing and found the guy in Sydney that used to do it no longer is there. Is there any place still around? If not I guess I'll cut the top and bottom off and hand port it.
