The mounting holes won't have to move, there's generally enough slop in them for offset dowels.

Mmmm....... 0 dial at 3:00 oclock and .025 at 9 oclock. AND 0 at 6 oclock and almost 025 at 12. I did it twice and came up the same. I dont have the flywheel on but will put it on this weekend and run the numbers again but i imagine they will be the same.

edit: The right side mounting holes are VERY close to the radius of the bellhousing that the bolt heads interfere before bottoming.

Well, a couple of things....

1. Make sure every bolt that's used to bolt the bellhousing to the block is in and tight.

2. Make sure there are no burrs, paint, powdercoat, etc., in the rim where the dial indicator rides.

3. You don't have to move as much as you think. If you're at 3:00 and zeroed, if you move the bellhousing .025" to the right to make the 9:00 measurement go away, then your your 3:00 measurement would essentially be -.025" and your 9:00 measurement would then be 0. You need to split the difference.

Use hex cap screws or small head bolts to avoid or cure this problem where the larger 5/8" hex tends to push the bellhousing aside just as it fully tightens, some careful use of a small die grinding burr on the housing at the point of interference will help make clearance if reqd also.

Thanks, I think I will do that even though the head will probably still contact. No worries, time to chuck some stainless in the lathe and make some tapered washers. pitiful, so much money spent on a product that does not fit correctly. Damn shame.

edit: wait a sec....die grind the housing at the contact point...hmmmmm, I shoulda thought of that!
