Default Torque converter installation question and problem

I have SBC with a TH350 transmission. We changed the torque converter out. When I installed it, it rotated over easy and seemed to be in the transmission correctly.

After installing the engine and bolting up the transmission, I notice the torque converter will turn (not bolted to flex plate yet), but it is very hard to turn. In the past when I put in a converter, I could turn them by hand to line up the bolt holes. Now, I have to put a little force behind it. Both the converter and crank are new.

It appears the "nub" in the front of the converter that fits in the end of crankshaft is really tight. It is not hitting or rubbing anywhere else. With no bolts in the converter, the bolting flanges are about a small finger width from the flexplate which I think is about normal.

Is this a problem?

Thanks for any help.
