40PC with 8.1 HO's top speed?

Does anyone know the top speed for a 2004 40 PC with 8.1 HO's 420hp.
Any idea of fuel burn rate?

Thanks

Per Formula's spec guide,32 mph,but probrably a little more,they are always conservative with printed speeds.3000rpm/18mph/27 gal/hr.4000 rpm/28mph/52 gal/hr,WOT 70/gal/hr.
