Hmmm. No replacement for displacement?
What about technology, design and implementation?
Engine (A) - a 627cc four stroke engine by manufacturer (A) makes a whopping 23 hp.
Engine (B) - a 600cc four stroke engine by manufacturer (B) makes 133 hp.
So if I understand Chris's argument correctly, since engine (A) is larger - it will undoubtedly be better than Engine (B)? I don't think the larger displacement is going to win out over design. This is obviously a grossly exaggerated comparison, but I think you can see what I'm getting at. A blanket statement like that is just doesn't work when it comes to technology and design.
Engine (A) = 23 HP Briggs & Stratton
Engine (B) = 133HP YVF600 Yamaha
Go ahead, but a bigger pipe and carb on the Briggs - it ain't gonna catch up.

Oh Gawd, is this thread STILL going on? hehehe
I guess it will for all eternity.
I have and like BOTH engines - I'm not getting into this fray again.
Yes Graphite - I've been playing with the R/T alot lately (gotta get it ready for the Lightnings at the Truckin' Nationals), but my 4.7 got a bunch of love recently too. It cooled off a little - you got that Duster done yet? LOL

If you do the same mods to a 5.2 and 5.9, the 5.9 will make more power. If you do the same mods to the 4.7 and 5.7, the 5.7 will make more power (although that's not a good relation since they are different). If you do the same mods to a chevy 4.8, 5.3, 5.7, and 6.0, the 6.0 will make the most power.
There is NO substitute for cubes!
Obviously I'm not knocking the smaller engines because I own one of them (5.2) but I'm not going to be ignorant of the truth! I've seen some quick 4.7's and 5.2's so I'm not saying they can't be made faster, but the bigger engine will always make more power because it has more CAPACITY to do so.

i agree with you. fords lil 4.6 makes good power though but in a way the viper is is kinda bad since its a 505cubeV10 compared to the 427ZO6 abd the ZO6 is quicker.

I was never impressed by the Viper engine. It's over 8 Liters! It's horsepowerpower to displacement ratio is sad compared to many other engines!

iimce tyou get to those size motors you start looseing rpm. look at a croch rocket. 14-15 THOUSAND rpm. look at a bigass 8 liter. mabey 10k if you build it right.
that is true about the viper. i never thought of how bad the liter to power ratio is.

in defense of the viper motor. the thing has
9.6 to 1 compression and has a flat tq curve. look at the vette 7.0L has 11 to 1 compression. the viper motor can make close to 2000hp with 21pounds of boost on twin turbos.
they might be making the 08 viper with 650-700hp
if you think about it there is still a lot left in the viper motor for improvement on hp. they just bump the power up a little when needed.
the need to make a hemi motor for the viper

haha yea it did get off the subject. but yea the viper can be very powerfull. just dont like the fact that it needs 10 pistons to do it. chevy has never had more that 8 pistons in production vehicals

whats wrong with having 10 cylinders? it gives the engine a different and more smooth power band and a odd sound :)

i will say this in the defense of the 5.9. the hemi may make more peak hp, and in so the new hemi powered vehicles will blow a 99 2500 v8 4x4 out of the water. but if you ever look at the torque band, even though the hemi gets more peak power, the 5.9 is still a better towing engine due to its excellent low end torque. its probably one of the best gasoline small blocks out there for towing and what not. not to mention its capability at handing abuse. the 318 as well for all this.
BTW, have you even looked at the new 4.7's? those things dont hit peak torque till 3600rpm!! thats crap! my 318 gets 300 ftlbs at 3200rpm. i would drag a 4.7 powered POS around!(same gears and all that sh!t)

I think the 4.7 and 318 are really close in power curves actually.
The 4.7 makes it's peak pretty close to the same area. My 4.7 NEVER had to rev to beat my bro in laws 2000 318 :)
The 360 is a reliable engine and always been a bulletproof beast. It's just old now, that's all. Emmission reasons are half the reason it's gone.
I have had all of them Dodge engines.
Having disassembled a 4.7 now, I think it's pretty high tech yet simple at the same time. Many things are actually EASIER than on the old engines.

jayb you're so full of it. hook the same load to both trucks with the same gears and watch the 4.7 drive away from you on a hill or onramp. the 5.2 hits its torque peak lower because it can't rev as high. i'm not sure if you know how to read a dyno chart but if you make the same torque number at a higher rpm its called more horsepower. that means it gets more work done because theres more area under the curve.

Going off of what you say, that's why the 4.7 only has a 235HP rating but 300ft lbs!
If it had an intake tuned for high RPM's like the 4.8 Chevy, it would make closer to 300 HP peak as well! But towing torque that I have come to love out of this small engine would possibly suffer.

I don't know everyone is talking about cubic inches. My 4.7L did a 14.3 in the 1/4 mile with nothing more than exhaust and an intake and I watched a 5.9 RT do it in 15.5. Both are 2wd and limited slip, mine has 3.55 with a five speed and the RT had 3.92 with an auto. Both regular cab short beds and the RT had the mopar cam, headers and intake. It seems the RT is not what it is made out to be especially since I paid only $15,500 for my dakota brand new. Although it does not have the wheels and fender flares that the RT has. I bought it because it is a sleeper. Dakota sport-looks slow goes fast, RT looks fast-goes slow. I have seen full size ram trucks run faster than that modded RT. So are cubes what they are made out to be...
