Hello,
I am getting my 292 rebuilt and took a the intake, oil pan, valley cover, fan, and a bunch of misc brackets to be powdercoated.  I also took the bellhousing in to be done.  The surface where the manual transmission mounts and the surface that mates to the block were powdercoated- am I asking for trouble if I mount everything up as is, or will the (potentially uneven) thickness of the powdercoat cause alignment issues?  I'd rather not break out the wire wheel but if the consensus is that it will lead to problems, I will.  Thanks!

Powder coat isn't much thicker than paint. I see no reason that it would hurt anything. Only possibility would be a ground problem but I don't think that would affect anything. Chuck

Moon Shadow may be right, but I never paint these surfaces as I want everything to mate up as original.  Same goes with the block where the bell attaches.

I painted mine. No problems at all.

Bolt up the bellhousing, put a dial indicator on the crank to make sure everything is aligned and then also check the flat area where the trans bolts and see how far it's out I'll bet not it not over .001"

I would remove it. It may not cause a problem but I am anal retentive about a lot of details.

Any paint or powder coating needs to be removed from both the block and bellhousing mating surfaces.  It only takes a slight mismatch at those surfaces to have the bellhousing off ever so slightly which in turn makes the transmission not exactly in line or parallel with the crankshaft.  In that instance and using a standard transmission, there can be some transmission shifting issues or a vibration.  All engines leave this shop with the blocks’ bellhousing flange thoroughly cleaned of any paint or residuals.

Just tell the Powder Coater to not powder coat those areas.
They have a product of sorts that will stop the PC from sticking.
I don't know what it's called

Thanks all for the your input.  I think the consensus is that it probably won't cause issues but there is always the chance it may.  I have all winter to work on the little details like this before it goes back on the road, so really no excuse aside from laziness not to.
