any long term reports on the longitivety of using these conrods with splash oiling?
Don't believe they will work long as the Babbitt is so thin, made for pressurized oiling. The old chevy's that used splash were Babbitt. KGB
In the 50's and 60's (microbabbit) bearings were sold for chev 6 motors, these had very thin babbit, and were very tough, saw guys turn 6000+ rpm often believe it or not Dave
The early 50's chevy rods had Babbitt bearings with dippers. Later on (54??) you could exchange the Babbitt rods for rods that were machined to accept inserts like the later 6 cylinder engines.
I have a set of new inserts that were used in the modified chevy rods. The inserts have deep oil groves to insure the insert bearing received sufficient oiling. Chevy's used oil pumps from the early teens to provide oil to the dippers for splash oiling.
The trick is getting sufficient oiling to the bearings. Fords stock oiling system is not adequate for insert bearings.
Insert bearings like pressure fed, filtered (clean) oil. Neither is available in a stock T. Guys that use inserts in model T or A engines with splash oiling change their oil very frequently for best results. Inserts have no tolerance for trash in the oil.
Les, chevy came out with inserted rods in 53 for cars with the powerglide trans, 54 they all had them. These engines also had a full pressure oil system. The early engines had an oil pump that supplied oil only to the dip tubes and rocker arms. I think I'm right, have been known to be wrong. KGB
6000 rpm out of a chevy six? Ive seen lots of those motors kick rods out if you went over 55 mph downhill. Scott
Your right Keith.
