<p>Complete fully modified/ported GP460 / GP470 long block for goped use. Long blocks are complete as shown in picture with reed crankcase, crankshaft and fully modified top end. Exhaust is not included and we recommend a Jetpro Rhino pipe to match.Transfer bowls have been modified so that a stuffing mod is not required like a stock case to increase power. Intake tract, reed valve and transfer bowls were in-house flow tested and dyno tested to produce as much power as possible. You can expect to see a lot more torque and mid range power then a piston port GP460 or GP470. We've used high quality carbon fiber reed petals for more power and longer life then fiberglass petals.&nbsp;</p> <p>Porting/machining:</p> <p>intake port filled and 2 boost ports added</p> <p>piston lightened/reshaped w/dual windows to match boost ports</p> <p>all ports resurfaced</p> <p>transfer port bridge knife edged</p> <p>exhaust duration advanced</p> <p>exhaust port widened and flowed</p>
