I was hoping this would be the final chapter in my heat riser project. Now I am not so sure.
The Ford spacer/blank from eBay arrived yesterday. The bolt holes were oh-so-close. I could get 1 thread in (on the second bolt) before it would bind down at an angle. I put a 1/2 drill bit through both holes and now it works fine. I just wish my problems ended there.
As you can see below the original riser is 7/8 thick. The Ford spacer is nearly double that at 1.5". I could probably live with that as well as I doubt the extra would hurt anything but there is more.
The inside diameter of the spacer is smaller then the pipes. I should have seen that from the eBay pic I posted last week but I was concentrating on the bolt holes. Of course this could cause a build up of carbon where the spacer and manifold meet. Also the cross over pipe has about an 1/2 inch extension beyond the flange that is inserted into the original riser (seen in post #494). It won't fit in the spacer so I would have to cut the extension off and I'm just not sure that I want to do that to a $500 exhaust system. Before someone asks, I do not have a lathe or mill to fix this myself.
I'm only $30 in the hole at the moment. I am sure there is a spacer out there that is perfect but there are no measurements for what I am finding online and brand new ones cost from $60 to $90. I'm starting to think that $125 for a new riser isn't so bad anymore.
What do you guys think?
