They make 300 from the factory and at 500 they scatter. Like clock work they pop every time. Sorry go buy one and find out. Also i dont think the laws of physics support your idea of a mod motor that turn 10k all day long. Since the valves to pistons size is not going to allow that much air thru the engine.

Dealer having issue blowing mod motors with graphite powder and letting them idle for ten minutes. Easily the worst decision in green energy future. Crushing good cars and not letting the only industry in the us that actually repurpose reuse and recycle every damn thing get it hands on all the parts to keep another few thousand cars running for years. It was a sad day in the hot rod world all around. Sep for the ford explorers they blew up. That was needed.
to be frank- or steve, or bob... you obviously don't know jack about motors- so it wouldn't surprise me if you didn't know how to take care of your motor pal. annnnnd i'm done following this. kinda pointless. just didn't want the world to be missinformed by you.

V10's sound awsome, I miss the V10 Formula one era.

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.
<- exactly what would have said... seriously. I think he just doesn't want to listen which is too bad. there is a lot of good on this site. a LOT of crap (seriously there is ) but there is a lot to learn from here.

(well my engine won't rev past 7.000 rpm, so it won't scream that high)
When all said and done my 337 sbc will be hitting float at 7800rpm

but it only makes 630 SUPERCHARGED. just do a simple power to cid ratio math.

I really don't know were did you find that: "Most chevy alum block motors will shame a ferrari v8 in power to weight and power to reliablity/rpm"
You are dead on here sir.

305 Engine Build Questions & Much More - Car Craft Magazine

A lot of tractor pull guys run big engines with 180 cranks. also some of the pro dragsters have tried them as well. But they dont work as well. as the gm crank design.

Its all still in the muffler. Once you got the music it will sound right at speed. Now you got to make your chevy v8 turn 8K rpm. You will also need four valve heads they sound very different. But can also be purchased.

You may want to check out what John Force racing is using there new race engine has a very unquie sound.

Ferrari wishes they had a v8 as compact and light as the sbc. Chevy has many of the best designs going for heads and crank positions. Since they all have major pattens applied you will never see any other maker use the chevy design. Mostly cause chevy knows they got the patten in early and have the best on paper and real word designs. a typical ferrari engine will weight 900 to 1200 lbs turn 8K rpm and only make 240 to 340 hp. Newer engines make more power per cube but do it with better flow and lots of design money. Most chevy alum block motors will shame a ferrari v8 in power to weight and power to reliablity/rpm. Flat plane cranks have some major faults.

SOO much wrong in all of this I am going to leave most of it alone seeing that you have already been corrected by another person thank god.

also so you are aware a flat crank would be a custom job in the 3500-6000 range. depending on who is willing to do it. crower will for a sbc for about 4k. its complete custom. my 3.25 forged crank cost me the price of free. i think i will stay with that.

They only sound slightly different because of the cfm through the rpm range. This is considering IF the motors were all exactly the same aside from the obvious pistons rods and crank. I mean bore heads etc.

The sound of a Ferrari V8 engine is unique to V-8 engines because it has a 180 degree crankshaft. A 180 degree crankshaft in 90 degree V-8 allows the engine to fire alternate banks of cylinders all the way through the firing order. You can also alternate banks with a 120 degree V-6, or a 60 degree V-12. A V-8 with a 90 degree crank fires right, left, right, right, left, right, left, left.

I know the exhaust system does affect the sound. But look at it this way. You can take a trumpet that Miles Davis has played, hand it to a 13 year old kid in Junior high band, and the kid is not going to sound like Miles Davis.
you got it

I have yet to work on one, i have heard them in person but never worked on one. just because its made by toyota doesn't mean its reliable...

love the sound though.

you would have to have pretty good ears to be able to hear any real difference in "smoothness" if both engines were uses a close as possible setup all around. BUT the firing order is slightly less stressful on the crank shaft in fords. they have a 4-7 swap compared to a chevy firing order.

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.
I have been contemplating if I should correct you in all the wrong in this.... the last time did on this SAME subject matter- it appears you did not listen hence why you are puking more nonsense. Not all of it, but a decent amount. Not trying to be a dick here but I really get tired of people ranting about stuff they think they know but have little actual experience on the topic. I tend to read, listen, and research than follow this stuff. yous should try listening a little more.

The most knowledgeable person I have seen on this forum in reguards to this subject is again- old boggie.

the 458 motor is detuned from the factory. even the italia. that is for starters. don't get me wrong i would not own a ferrari if you paid me to. they are pieces of ****. I have worked on too many to like them. They DO break just like the lesser crap too.

The motor I am a fan of is the ford modular motor. There is a reason that konigsegg used that block (but heat treated) in their little monster of a car. Its absolutely bullet proof. When that cash for clunkers bs was going on, the dealer next to my old shop had been blowing up engines all day or weeks. The one motor that they ever had issues with was that ford 4.6 mod motor.

I am looking forward to working with a bear bones coyote motor myself.

Personally if I was going to build my car again (instead of the sbc i have) I would have used a ford 4.6 svt motor get rid of the silly blower they have and go na with a cross plane crank and hit 10k rpm all day long. THAT would be a not so bad idea. I am not sure if anyone uses a flat plane crank for the mod i would have to look into it.

also - have you ever heard a borla? Like in real life? Compare that exhaust on a mustang and bmw e93. the bmw e93 will sound almost exactly like the mustang with borla exhaust. american muscle puke noise. they are not at all "euro" in sound they are low and rumbley in nature.

that sound is close with the corevette corsa pace car exhaust. though still not quite. the exhaust pulses are not even enough to hit those high notes because of the configuration of the crank shaft- or if you prefer, the headers. The factory headers on the ls1 and up are tri-y headers. at least the ones i have seen. they don't quite equal out the pulses like 180 headers.
