Busa rods shouldn't be a problem at that power but pistons won't like it - I wouldn't trust them as they fail in Busa's @ sub 300hp and that is with proper ECU engine management! With carbs and a Dyna it'd be risky - A dyna 2000 won't give any retard 'curve' - it just drops a set figure from whatever the programmed advance curve is at that point.
i run a draw thrù. Dyna 2000 and a prèssuŕe switch in plenum.38 degree ignition 12 degree retard on boost. Dyna 2000 has 4.8.10..12. 16 retard
