<VV> engine knock

[Dennis Dorogi]

A guy from a nearby town brought over a 63 Spyder convertible with a 95 hp engine in it.  It has an engine knock unlike anything I have ever heard.  It is a very pulsating knock and you can feel it when you touch the engine or while driving it.  Pulled plug wires and there was no difference in the sound.  It recently had the rod bearings replaced and almost sounds like a bent rod.  What would happen if a rod was rotated or the numbers not up as they should be.  Would this result in a knock?  It is the only thing I can think of.  It doesn't sound like a main bearing but I guess it could be.
      The engine seems to run and idle OK but it also has no oil pressure showing on the guage but I think that is a wiring, sender, or guage problem as he drove it over 40 miles to get here and it is still going.  This is not much to go on but I think it has something to do with the rod bearings being worked on.  They were replaced with standard inserts but  the originals didn't look that bad to me.    Any ideas?   Dennis Dorogi
