Yet another bogu horsepower factor

Charlie , I'll ease up on you for a while and move on to maybe the most bogus of all the new cars horsepower factors. Check out the 5.7 hemi from Chrysler/ Fiat. It's the same motor as the 6.1 just less 25 cubic inches. It's rated at 305hp. Let's take a look at the specs boys and girls. It's 12.7 to 1 compression, it has a 584/552 lift cam, it has a single plane intake that is cast although it looks like a sheet metal manifold. It has a 1000cfm throttle body, a super stock oil pan and heads that flow well over 300 cfm right out of the box. Now let's compare this little jewel to the GM LS1 in the automatic version which is rated at 373hp unless you have a GTO or a Corvette and that's another story entirely.

The LS1 is 10.2 to 1 compression, it has a 515/515 lift cam, it's got a plastic manifold, a throttle body that is 2.954 round, a street oil pan, and good heads, although I bet they don't flow anywhere near the hemi heads on the Chrysler motor. Oh by the way the LS1 is 346 cubic inches.

The Chrysler should easily make 600hp. Any of you proponents of the new cars want to try and defend this deal.
