GM claimed the "Squirt Holes" in the Small
Journal rod was put there to lubricate the piston skirts
and was later found unneccessary, being dropped with
the introduction of Large Journal Motors. As we all
know, the SBC is harder on camshaft lobes than some
other engines. I have discovered, over years of tearing
motors apart in the wrecking yards, that less cam lobe
wear is found in Small Journal engines. I supplied oil
pressure to an assembled Small Journal 327 with the pan
off, a controlled experiment. I discovered the "Squirt
Holes" also spray directly on the camshaft and lifters.
Not the best thing for windage, but an important
consideration, I think, for a street motor. As a result, I add
the holes to the Bearings and Rods in my Large
Journal buildups...Robert
