Why is the Hemi been so dominate for so long? I do believe it's staying as THE power source in racing is longer than the Offy.

Why can't a big block Chevy compete.

What happened to the SOHC Ford.

Oh and fuck electric anything other than to start a car.

I think the Hemis opposed valve layout can't be beat is why it lasted.

All modern DOHC Engines are pent roof with opposed valves.

BBC is king when it comes to inexpensive durability with parts commonality.

Even Ford gave up on their SOHC and went Boss until the 4.6 and its successors.

Note Ford went back to rear sump with the 4.6 and on after decades of dumbass front sumps.

Fords new 7.3 L pushrod big V8 is trying to capitalize on the BBC's many decades of popular success.

If Ford ever Turbocharges it that will be a total game changer!!

Evidently their DOHC V8'S aren't strong enough to Turbo.

It seems no domestic V8 is strong enough.

They all make do with Supercharging.

So not matter how many cubic dollars that could be thrown at the BBC or the SOHC it would never beat the hemi? i just find that so interesting. But then those hemi's are pushing so much HP that they compress your chest when they launch.

When talking pushrod Engines the Hemi design is superior power wise.

Complexity and emissions are where the Hemi advantage diminishes.

Cu in for cu in a DOHC 4 Valve Engine certainly takes the lead.

The SOHC is simply out dated power wise and its long timing chains.

BBC is tough, simple and relatively inexpensive.

But Turbocharging is changing the world.

Turbo LS now rules with many.

It's tough, cheap and simple.

Imagine a Turbo GT 500!!
