I am looking at a lycoming 13B27120 for $6,000 verses a Superior SL-36500-A31 at $4,000. Does anyone have experience with the differences and is it worth it?

They both are setup for a constant speed propeller and are non-counterweighted.

Only difference is the manufacturer

The Superior crank is equivalent to four different Lycoming part numbers including the one you list.

Crankshaft

thanks Gil, that is good information. Superior is changing vendors giving a 2 year leadtime and no one stocks the item so it looks like I will have to go with lycoming.

ECI crank

I might have a ECI crank in the same configuration for around 4800.00. Save you a bit and they don't have the AD if you convert to fixed pitch. You can call the shop if you have any questions. I haven't been on the computer much lately.

O-360 crankshaft

The Continental "Prime" aftermarket crankshaft equivalent to the Lycoming 13B27120 is part # AEL36002-1. It has a robust solid flange that is .44" thick, 1/2-20 thread flange bushings, and is set up for constant speed propeller operation. Aviall have them in stock. They are a more affordable alternative manufactured and backed by OEM Continental Motors.

Agreed.

James is correct. We have had good luck with the AEL cranks and I specified one for my personal engine in our 8 and it has done very well.
