if its not got HEMI on it, its not a hemi, and if its not in a 69 charger, its in the wrong danged car!

 

LOL... Most modern engines are variations of a hemi engine. If the valves aren't parallel, then it's a hemi. I don't know of very many modern production cars that have flat heads.

Furthermore, the original hemi WAS a beast of an engine... And particular race applications benefited from FI. But in terms of modern day engines, both the old school AND new school hemi are rather pathetic when looked at on a HP per liter basis. Why does it make so much power? Because it's monstrously HUGE. Besides American cars, most cars that sport engines of 5.7L or more are SUPERCARS that completely embarass any hemi model. What's great about today's "hemi?" dodge can build 'em cheap and dirty!

But I am talking about street cars, where these engines are rather inefficient and worthless... But when it comes to high HP drag racing... Well nitro methane, and gobs of power can't be handled by today's modern engines, as there are too many moving parts and light weight materials to sustain the abuse.

But IMO a 6.1L engine that produces the same output as a Japanese 4.6L is unacceptable. Even the corvette's 5.7L blows away the hemi! But hey... They CAN build them cheap...

 

the new hemi is a half a hemi, its not a full hemispherical head

and the old hemis could easily handle 1500 hp, they even had one that out of the box produces 585 hp at 3500 rpm, and 600 ft lbs of torque at 2500 rpm

 

There is no doubting the power handling abilities of those engines. The sheer mass guarantees it. Keep in mind that they had much bigger displacementa too... A 5.7 is no bigger than a 350... But by nature, larger engines are not more efficient, but they are necessary for high output applications 1000HP+. A full hemispherical head is not needed, nor is it really going to be more efficient. Computer optimized flow designs will blow them away.

 

yea, but a hemi would be crazy in an xb... unfortunately a crate, true hemi is 15k


I've already looked into swapping out the wimpy 1.5ltr for a hemi

 

With that much output, I hope you plan a RWD conversion, not to mention all the added weight! If you plan on power output of less than 800HP, you'd be better off with a smaller more efficient motor!

 

no I'm looking at one thats base, then building it to equal 1200 hp minimum, rwd, manual 6 speed, with a/c and a second compressor, cause regular brakes won't stop this beast

 

If you are going for cool and unique points, then kudos to you. But for this kind of project, you really started with the WRONG car. You can buy used old 280Z's and they actually make pre-fabbed kits to mount 350CI motors... But hey, I can appreciate any modder's Frankenstein!

 

yea but if I'm buying a nissan I've got a 240 motor/tranny/shaft in my shop with 10k original miles on it, I'll go for a full show, cruiser car

nah I'm a toyota/dodge guy, and trust me if I could afford to do it, it would be done, I'd have that hemi in the backseat

 

btw, this is a 8.0 L engine, for a side not, its not going in my xB, lol. The engine was ran low on oil. burnt oil and marks on the inside of the cylinders. Maybe if i had the money to buy a good running V10 an tranny, with a rear end, lol, then i would. But im poor, lol.

 

chrysler was the first company to get banished from nascar cause they always won

 

Are you suggesting the 9000 hp keith black hemis that are sported in top fuel drag racing are not modern?

And I'd have to suggest that the v8's in F1 racing that run between 18k and 24k RPM for hours at a time aren't simply "modern" but border on alien technology.

 

almost all motors nowadays are hemi's......

 

yup all over head cams are hemi's a pent roof hemi http://auto.howstuffworks.com/hemi2.htm

 

You'll have to excuse my use of the word, but you're taking it out of context. By modern, I mean modern design. Heavy pushrod iron motors have their place and application, and are sometimes better suited to certain tasks, ie drag racing. But by modern, I mean DOHC motors with electronic valve timing management and other "modern" bells and whistles, that are superior for road applications. The primitive engine designs are not inferior in any way, they are just better suited for certain applications. And yes, I know that the have some modern aspects as well, but i'm using the term to differentiate between the two.

 

heres the old V-10 now cleaned and repainted!!

 

are the lifters still in it???

 

yep, has the lifters, some are broken. not sure how they got broken.
