0470 GPU cylinders

[airboatman631]

Any recomendations on a good machine shop to overhaul cylinders. Also if I have them drilled for the extra plug and add the second mag, what kind of power increase can I expect?

I'm not really sure the extra mag adds a noticeable amount of power, but I can tell you it makes them idle smoother, especially when cold.

Thanks guys. I am going to get in touch with both of these guys. I'd really like to trade my gpu for a 520, 550 or 540. DREAMIN'!

JC can do a conversion on your gpu to a 520.Skeeter is running one of these engines and it is really strong.

JC and Ben can easily get you 300 HP out of one of their conversions.Give them a call.
