Why go as far as designing and building a new engine and use old dated technology like push rods
Can`t see this thing driving anything but a cruiser type bike.

What I would like to know is were does all the money come from for a project like this ?

just because it is pushrod does not mean that it is bad technology, it means that the engine can be kept light and compact.

I dont understand why people think that it must be terrible as soon as pushrods are involved, some of the highest hp out-put engines (at the moment) are actually pushrods.

could you imagine how big and heavy this V4 would be with a quad cam? For not much of a gain either.

And if you even dare bring up harley motors I would suggest you dont, these are massive air cooled machines that due to the crappy metals used to cast them and the freaking massive pistons used (some are almost a litre per cylinder) combined with a stroke as big as a coma patient... ofcourse they are never going to rev hard or put out much power. That is a completely different argument.
That being said... the torque on those things are nuts.

The only reason a can see why they are using push rods is to keep the height of the motor down.

I still think you would best to go for overhead cams with buckets and shims for a high performance engines as opposed to cam followers, rods and rockers bouncing around at 9000 - 10000 rpm.

pushrods can be pokey!

...... top fuel dragsters are still, by NHRA competition rules, forced to use two valves per cylinder and pushrods and they kick out 8000hp!
