220 GPU Conversion Parts

[Des Moines Boater]

I have the PE-150, 220 GPU and I want to change the cylinders to the O-470. Do I need different push rod tubes and push rods, different valve covers, piston wrist pins? I heard the O-470's will bolt right on, but I need to know what else I need to convert to the dual mag system.

Also the mags are suppose to be the Bendix S6LN-23. Can I use the Bendix S6LN-25 or is there a Slick mag with impulse I could use?

everything will bolt right on.that is what i did to my motor. you will need piston for aircraft, cylinder's , value cover,rocker,rocker pins and fuel tubes,carb,mag gears,mag ,plus the pin the mag sits on.you will need to have someone drill two holes foe the mag pin to bolt to.make a big difference. i would say the best person to talk to is jc stanley,here is his phone#1-407-927-9701

Thanks for the information. I talked to JC Stanley and he was very helpful. He told me all the things I need and what to inspect when I take off the other cylinders. I forgot to ask about what magnetos I need but I can find that out later. The single mag is a S6LN-23 but I think the O-470 calls for the S6LN-25.

i was looking at doing the conversion too, just out of curosity, but what does that finished job run, price wise? just a rough ball park figure. are cylinders still running around $250?
