Super Rare Vintage NIB FF GP Custom K&B 3.25 Competition Engine


Ultra RARE 3.25 K&B free flight or pylon engine. These unlike the 3.5 were only produced for a short time! These are GP custom models. Looks to have been match ported and polished and both are setup for Nelson type plugs. Both new never look to have ran!

$135 each or $260 for both! Shipping is $12 either quantity!

Pm me if interested, PayPal preferred! Thanks

I hope this is not a dumb question, but what is a GP?
Also is one of the back plates a custom one? I noticed it looks a little different than the other one. Thanks!

Looks to be a service to hop them up. Aftermarket?

The one with the scratched up head needs the backplate rotating 90 degrees, that's what you're seeing.
