One thing you forgot to mention Harry and its worthwhile is that the Moron-aro used a special race prepped 7 litre engine that has a power input to a 240v main to warm up the engine oil to 100 degrees celcius before cranking it over or it would self destruct. Jee I wonder how many of these specially engine Moron-aros are on the road?

As for pushrods I love a good hemi but wanker GM, Ford and Jag got rid of the 13b at Bathurst even after they restricted its porting to Bridge from Peripheral.

When the rules where the same for Mazda at Le Mans as for every other car maker the rotor won and then got banned thanks to the other companies lubing officials.

When the game is fair the best technology wins in races and in the air. Twin Cams, rotors, modern 2 strokes etc.

Show me a pushroad bike that can match a 1300cc hayabusa.

A little 1300cc suzuki swift engine will outlast a pushrod 1300cc without a rebuild 4 times over and yet be no where near stressed.

As for Indy with turbocharged engines you must check out whats running now in those cars... anyone say twin cammed v8s?

As for F1 what pushrod can reach 17,000 rpm?

Oh and to build a chev to match a old hemi you are dreaming and eating too much junk food.

Time and time again its proven the hemi is king and Keith Black has shown why.
By the way a cast iron windsor v8 is lighter than any cast iron chev v8 ever made but I guess being a blind chev nut really makes you blind at everything. A windsor v8 is lighter than an nissan L26 by about 8-12 pounds so please stop dreaming.

For big ass engines pushies are the way to simplicity and you cant beat a mopar crate engine with normally aspiration....
