Shoe is probably right, but....

If you did lose a press-in plug, you should have also noticed a significant drop in oil pressure, which you didn't mention. If you did have a drop in pressure, and you use hydraulic lifters, one could have collapsed and the pushrod could bend with the excessive lash or even pop out of the rocker and bend. Still, the last main bearing cap can be a little devil what with all the silicone and rubber sticks and nails, etc. And very difficult to change in the car. Are you sure you got it done right? Did the machine shop refinish the crank where the seal goes? Maybe the diameter is too small now. Or maybe there is rust on it that destroys the sealing edge of the seal (which should pint to the front of the engine). On the small blocks, there was sometimes a metal pin to help hold the old fashioned rope seal. This had to be removed when changing to a rubber seal. Something to look for. Oh, and the only time I ever bent a pushrod, it was my own fault during disassembly...don't even ask. Could your engine builder have done this? Let us know what you find out.
This thread, so far...
