Heres my 470 Cannondale vrs a new stock ATK vr450 Witech Engineering ported head, Timbomoose custom stroked crank,custom velocity stack. Stock cams,stock valves,stock fmf exhaust ,450 cc wiseco piston,early mc500 fuel injection , Harley Davidson 88CI injectors. Powerplant parts were used or donated for the project so cost was under$300 including $180 for a new muffler. Running gas.
This is the most sustained rear wheel power ever from a Cannondale but very soon it will be outdone by the wave of big bore stroker engines in development (500cc plus) several 505s are running in test phase now.
