I have some early conrod bearings which are factory ford, they DO have the oil hole in them.
I contacted Repco who assure me that ACL brand 351W conrod bearings DO NOT have an oil hole built into them, so that leaves me wondering whether some years ago Ford decided the oil spit hole was a bad idea for whatever reason, (loss of oil pressure, too much oil spraying on the cylinders causing premature oil usage, don't know), and the idea was abandoned by using solid conrod bearings.
Thanks anyway, just thought there might be a Windsor person from way back who could pin an answer on this problem.
Bugger it, I think I'll tip towards getting the bearings drilled to match the conrod, I'd rather have oil spraying around inside the crankcase than dry bores and gudgeon pins.
