    By the way... basti08 said .7L (700cc) not 7L. He's comparing the highoutput 5.0 liter V8 of the E39 M5 and the regular Hemi V8 found in the Chrysler 300C.

    by the way, the 300C's sibling the Dodge Charger has an optional Hemi on the R/T models that produces an extra 10hp from the same 5.7 liter Hemi engine.

    Actually, most of today's clever designs were invented or thought out way back in the 1930's and during the war. It just wasn't practical to produce without some other technology back then that we have now i.e. metallurgy, computers, petrochemicals. Basically 1930's internal combustion technology is already very much "perfect".

    Just a question to the people who say that the American V8 and all it's evolutions are low tech, have you even driven a car with a displacement of 5 liters and up? Once you have then I think you can make comparisons but until then all you are doing is speculating on it's performance based on data sheets not actual driving of the vehicles with these engines.

    To say that GM will kill the 350 and it's cousins is crazy since they've just put variable valve timing on it. The engine is the most widely supported motor in the aftermarket industry. Heck you can even buy crate motors based on this design, AFAIK nobody makes crate motors for the B16, VG30, 2JZ, etc. You can take a block from a 70's 170hp version of the engine and put EFI or new carbs, change the heads, cams, and make the motor produce 400-500hp easy w/o superchargers or turbos. How many Japanese or Euro engines from the and 70's can you say that about?

    Comparing the 0-60 times is pointless since the times are dependent on gearing in addition to the power.Comparison of the power output is also useless since most of the American engines mentioned are tuned on the conservative side and a simple retune can get lots more power. Comparing a highly tuned BMW V8 to a conservatively tuned Chrysler or Chevy engine isn't very fair.

    *gasjunkie-The Cobalt uses a DOHC engine called a ECOTEC not a OHV engine. BTW in compact car drag racing that GM engine has been out performing the Honda's and Toyota's for the past 2 years.

    GM's 350 cu in(5.7 liter) V8 has been replaced by the slightly larger 400hp 6.0 liter LS2 V8 on their production cars, the 350 is still available as a Crate Motor.

    The 6L engine is still derived from the 350ci motor and is a evolution of it, so it isn't an entirely different engine. Old 350's could be increased in displacement up to a 396ci iirc with stroker kits.
