I'm going to guess that you really don't know a lot about the lsx motors by what you have been saying. If you look into any of the cars in nhra that are lsx powered run entire seasons on one build, some run even longer. I'm not saying that they have to be overhauled either (new season, new motor). Of course I'm talking about motors that make 800+ horsepower for the record.
F1 motors aren't even in the same league. They are a different style motor and are built for longevity not a pass down the strip. They have no stroke and have to rev to reach their powerband.
Last but not least....you have to be kidding if you're honestly saying that the 4.6 is a better motor than the lsx series motors. Any company could have "overbuilt" a motor from a factory. I hate how people always use this as "it's a better motor" argument. The lsx out flows, performs, and revs.
Those are not the only classes that get rebuilt that often are you forgetting Pro Stock. There are plenty of 1UZ's in NHRA that compete with LSX and do just as good. I know enough about LSX ENGINES to know that it's not gods gift to the V8 world. Yeah and Chevy/Ford/Nissan/Toyota/etc can do 800+ forever if built correctly so why would LS1/X be any different then Nissan/Toyota? Im well aware how F1 engines are built, short stroke, lack of tq, but make more power, you don't need 800 ftpns of tq in a 1200 pnd car. Once again I didn't say it out preformed an LS/anything I was using it as an example of how much lift a OHC engine could accommodate, jesus read.
You guys are stuck in Chevy world, any of you ever even thought about coming out of your domestic box and just LOOKING or doing any kind of research on Nissan/Toyota V8's or OHC designs? I doubt it. What do you know about 1UZ/2UZ/VH/VK to argue. And FYI that drag soarer I posted runs stock ported heads supporting over 1300whp so I think they got potential.
This has turned into a LS1 Vs Everything argument, and I didn't want that but of course everyone thinks im bashing LS, LS engines are the best EVAR, blah blah blah. Im not im comparing OHV to OHC READ.
And PoorBoyBrian im not even go to respond to that cause you just make yourself look retarded.
