The Ferrari technology is way superior to chevy's, of course it comes at a price way superior than chevy's

My point is this guy said that a chevy engine is better.. no way, it is not, and I'm a chevy man.
Uh well if money is no object you kinda end up with a 8000 hp dragster engine. Yeah not wedge heads but niether do f1 engines use production style chambers.

Point is 9k rpm chevy is going to sound nothing like a 5k rpm engine. And if you stuff a 9k rpm small block motor into a ferrari that had as much time spent on performance as the normal 458 forget the italia. It would make alot more power than ferrari engine fit the same space and less lbs. A lot of people think euro motors make more power since they rev higher and produce power at lower displacements. Truth is the motors are all let out from the factory nothing left in em. With more displacement they would be bigger than desil truck motors. And 8L v8 made with bmw or ferrari or porsche blocks would be 6 inches taller than a chevy and make the car handle like crap. With lots of top heavy engine.

Chevy with 8L engine running 5k rpm max will make about the same power as a 4L euro block turning 8k rpm. Aboit 400 hp properly tuned. Now spin that same 8L engine to 8k rpm with big cam and air flow to support it and you will hit the 800+ mark.

Only advantage the euro engines have valve lift and leverage on the rockers. Four valve engines use less lift and dont need as much spring pressure. But flow is about the same when the wedge is double the size of the pentroof heads. But you can get four valve heads for the chevy. And this is how all this relates to the post four valve heads change everything the sound is completly different and engine is more free reving with the heads.

Now add up 180 crank four valve heads and high reving forged engine and proper cam to reach that rpm. Then you will have a 800 hp engine that cost 15 grand and only sounds remotly like a ferrari. For the same money you could buy a used ferrari engine and get it installed.

Bolra has already spent the millions to develope the euro sound for the v8s.
