Does anyone have a known good source for a crank socket for a BBO? I did some searches and found this on Summit.

Not sure if they are an ACTUAL fit or not.
Any other sources?
TIA,

 

It will work but it will not be perfectly true to center if you want to use it with a degree wheel. The Mopar crank snouts are 1.535 or so and the Olds is 1.500 So you have to use the setscrew to keep the socket biased in one direction a little bit.

Not sure if anyone makes one that actually fits Olds properly.

 

I really only wanted it for turning the engine over without a damper installed. I don't like how the setscrew will likely slightly damage the machined part of the snout. I think it would have been better to have the setscrew crank down on the key...

 

I've got the Chrysler socket. Shim stock is the way to get it concentric. Of course, that assumes the socket is machined concentrically and the degree wheel is similarly concentric.

 

I have a Olds crank socket that fits the crank very snug. I also have a Manley camshaft degree wheel that fits the crank socket. I have have both for probably 20 years. I don’t recall where the socket came from. I would think Rocket Racing or another Olds specific vender might stock or make the tool.

 

If thats all you want it for I generally use a crank bolt with a big thick washer.

 

I have the the Comp Cams socket, it fits and works well. Perfect for use with degree wheel.

 

I went ahead and ordered the Comp 4799 socket from Amazon Prime. Saved $10 shipping that I would have paid to Summit. Thanks guys!

 

I use the Comp one, it's good. Don't crank down on the set screw - just turn it in enough so the socket doesn't fall off. I normally don't tighten that at all - just slip on and go.

If all you're doing is turning the engine, then just use the balancer bolt. It's plenty big to get a good hold. e.g., that's a real pain on a SBC where the balancer bolt just has a normal 5/8 head, so it's tough to get enough leverage to turn over a fully built engine without damaging the bolt. But the Olds 1 1/16" headed bolt? Easy.
These sockets do make using a degree wheel much nicer.
