Small Block Windage Trays Exist in Different Profiles?

were 340 and 360 main caps the same height/bolt width? I asked the fella that I bought the tray from and he told me it was for a 360 as the part number was different than a 340. Don't know the diff as I never had 2 side by side for comparison. Rumble, you got 5 minutes to eyeball both models to see if there is any diff besides the bolt hole shape? Im thinking the depth of the bolt hole from the OD of the tray would be the only difference I could imagine (360 being a deeper stamping) if it were in fact a stroke issue. Or the part number changed to signify the oblong bolt holes...Interesting. IIRC the counterweight dimension is most likely the same. if that were true then the rod journal would be farther out from CL and the rod caps/nuts/threads would be farther out too.
