I have a 1996 chevy blazer (s10) with the 4.3L and am having trouble finding the correct information on where to put the oil holes in the cam bearings in relation to the oil hole in the block.

I can someone please point me in the right direction on this?

 

The exact specs need be found somewhere else. Maybe a forum member has been on this track before.

IMHO

In general all small block engines from GM are bored from the crankshaft mains into the cam bearings.

The cam bearing bore may even have an annular channel.

Normally there is only one feeder hole so the bearing should be aligned with this bore.

Hope this helps.

 

Thank you
