I dont know if anyone has pointed this out yet but line up a stock ZO6 vette vs. a Stock 03 cobra...lets see here 5.7 ltr pushrod v8 400+hp vs DOHC 4.6ltr v8w/8psi intercooled roots blower 400+hp lol and the cobra motor im sure has larger dimensions...so pound for pound they have the same power but look at the gas mileage i know the cobras is rated at 22mph highway with the 6 speed and id assume the ZO6 is around 25mph so if hp isnt being beat & mpg isnt being beat & space saved isnt WTF were they thinking?

the stroke on the 4.6 really isnt that bad at 3.55.the 5.4 gets a little long at 4.16 but there are still guys buzzing the 5.4 to 8000.
also what a company does and what a company is capable of doing are two diffrent things.

Line up a 1990 ZR1 (they were the fast ones) and a 2004 Z06 on any track or street. I think you'll find the LS1/LS6 pushrod engine wins everytime.
Less cost, more power, more durable, easier to work on, the list goes on and on....
I think you'll see GM as a whole is moving away from OHV configurations and moving back to pushrods. The only OHV engines GM uses now are the Northstars...and that is a late '80's design engine.

I have seen some pretty amazing zr1,s!!!
i was at a 1 mile top speed race and there was n/a 415ci. zr1 that produced 680rwhp,and this was with parts that are 10 years old.this engine DOES have more potential.if it were still in production after this long it would have probably been making over 500hp out of the factory easy.
btw....that zr1 went 190mph in one mile the only other faster n/a car was a viper that developed over 700rwhp and it went 191.

uhm, i think you should go back to 1401 chemistry and ask your professor which one is strong, iron or aluminum.
and for your automotive aptitude, i really dont what you talk about when you can not see which element is stronger in which application.
one more thing , son. my knowledge in science far more than you big brain can think.

camaro z28 LS1 has less power than twin turbo supra. but if i put a supercharger or turbo in this LS1 monster, it could have more than 500 HP with stock displacement
LS1 is a big engine 5.7 liter. so i think it is made up for what it does not have. toyota 8 cylinder engine in the new 2005 supra produce 350 HP, and it is only 4.0 liter, but with twin cam and dual valves,
to me, GMC is the best in making V8. my second favorite is toyota. i dont like honda b/c they love to put Type R sticker on their slow cars.
and one more thing Aluminum is not a good heat conductor like iron, but it is lighter, about half when compare to iron.![Burnout](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_burnout.gif)

take away the turbos and then you can compare the two engines
supra has less power
i agree, gm is awsome in the engineering department of there engines
you cant find another engine that is as light, same size, natruly asperated,
and be more powerful.
and i dissagree with iron being a better heat conductor, aluminum conducts,and disapates heat faster and better than iron.
they would not use aluminum as a heat sink for electronics( amps, sterios, coputers, radeators, ect...) if it didnt

Your science teacher will agree with me on that if they know anything about metallurgy.
I would provide examples but since "you big brain can think" so well I shouldn't have to.

what about a ohv 4 valve head that bolts onto our short block. thats what i want to see. more valve surface, more cfm, and more velocity.
also, alot of you guys are comparing alot of detuned motors 4valve motors to the ls1. dont get me wrong i really think that the ls1 was handed down by god along with the lt-5 and the new and old hemi. but these motors you are compairing are either ford
, in a family car that still produces 300+ hp, or a detuned as hell (lt-5)
oh, and whitehawk you compared the new hemi saying it made same as a ls1 and less than a ls6 i hate to sound mean but duh, dodges new hemi is their common truck motor to compare it to a high performance motor only offerd in a zo6 come on man. and it holds up to the ls1 to bad for the iron block. not sure if you were insinuating if the new hemi has 4 valves or not but fyi it doesn't actually they changed the angle of the valves so it would be more unleaded gas friendly. so you compared a 2 valve against a 2 valve sorry to single you out but thats the main thread that bugged me.

Hey, I know everybody is having a grand ole time with this one, but don't forget, when it comes to big-***, no-holds-barred peformance, the top engines have DOHC. T/F Hemi, IndyCar, any Le Mans runner.
This is like the argument about whether a man or woman is stronger. Amusing when you're talking in a relative sense, but when you reach the literal extremes, there's no contest. Not that there's anything wrong with that,and I mean this in the nicest possible. way ....
