Yeah, I need 3mm more diameter. I measured it (twice in two directions on different days) at 67mm. I guess I did have a really nice manifold when I got the car. Everything I measured on mine is pointing to Dual Honed, but I have an early 1999 SVT. I wonder why? Maybe they screwed up and ran it twice when they were honing it. I suppose I am lucky because that means the the inside where I can't get to is probably pretty good.
? Will the stock intake rubber tube(accordion) fit onto the 70mm TB, or even the 65mm?
Switching gears: Has anyone had any luck with that "spacer" to cure the area where the air deadheads into the manifold? I haven't seen much more talk about it and I wanted to know whether I should be developing something for it.
