Oil Slinger

Am rebuilding a 327 and an old time mechanic friend remembers these engines as having an 'oil slinger'. There is some refrence in old motor books about the early 327s having one yet the later do not. Should we be looking for one or did it prove to be not needed?

The oil slinger shows in all the Shop Manuals through 1961, but I don't see it after that; apparently wasn't necessary.

if i remember correctly, the 'oil slinger' was behind (or in front of..) the crankshaft timing chain sprocket.

The '55-'64 SBC engine parts illustration shows the slinger but is listed N.S., not serviced.

My memory tells me the slinger went away in '58 but don't bet any money on that. I know passenger/Corvette 327's didn't use them.

You're correct. The timing sprocket went on the crankshaft first and then the slinger. Slinger was between the harmonic balancer and the timing sprocket.

Now, just to be sure we're all on the same sheet of music, are you sure you're not confusing an oil slinger with the SPACER that was used on ALLLLLLLLLLLLL 55-62 Vette engines????
SOME people in past years have confused the two.
Since the 55-62 engines are mounted with a crossover mount that is installed BETWEEN the block and water pump, this moves the water pump pulley AWAY from the block (by the thickness of the mount, about 1/8in). Consequently, AFTER the crank timing gear is installed, it is important that the spacer is slipped onto the crank snout, the timing cover is installed and then the harmonic balancer is installed until it bottoms out against the spacer.
Over the years, MANY, MANY people have unknowingly, or intentionally, or just out of stupidity omitted this spacer and then can never understand why the crank/pump/generator pulleys don't line up!

Nope. The slinger was a round stamped sheet metal offset disc that went between the front of the crank sprocket and the balancer hub; on a Corvette engine, it went between the crank sprocket and the spacer ring. I think most of the original slingers got thrown away during rebuilds. The original engines in both of my 57's had them.
