A lot of these cars are underrated, so I’ll post real life actual numbers 2003-2004 Mustang Mach 1: DOHC 4.6L 4v V8 (281ci) 10.25:1 CR: 320hp/320tq (actual) 2005 Mustang GT: SOHC 4.6L 3v V8 (281ci) 10.1:1 CR: 310hp/325tq (actual) 2003-2004 Mustang Cobra: DOHC 4.6L 4v V8 Supercharged (281ci) 8.5:1 CR: 430hp/420tq (actual) 2002 Camaro Z28 / Trans Am: 5.7L V8 (346ci) 10.1:1 CR: 350hp/360tq (actual) 2002 Corvette Z06: 5.7L V8 (346ci w/revised heads/cam) 10.5:1 CR: 405hp/400tq 2005 Corvette C6 / Pontiac GTO 6.0L V8 (362ci) 10.5:1 CR: 400hp/400tq Given Ford’s displacement disadvantage theyre doing pretty damn good, compared to the bigger GM engine’s, huh Shag? That and losing 2 full points in compression to the Z06, so of course, they made up the power and then some with an SC. You can’t really compare everything, theyre all valid ways of making power. But if you really want to throw in some NA engines for fun, then why not look at Ford’s 5.4L 3v engine, thats rumored to be in the 06 Mach 1? 385hp/370tq out of a 5.4L That’s still smaller than GM’s LS1 ---

Here’s my opinion on it… GM stays w/ the OHV engine for some reason… it seems that its pretty obvious that the DOHC engines and more than 2 valves/cylinder engines that Ford puts out have a lot of horsepower for the size… but there has to be a reason that GM just sticks with making the engine bigger, and leaving the OHV, 2v/cyl. in place, to create horsepower… Maybe its easier to modify engine internals … seems to me that the GM engines are more often torn apart and have internals changed to create more hp, while ford engines have to go with forced induction… i dunno… just a little insight… I love that cobra at the beginning of the thread tho… funny that w/ 690 horse it only ran a 12.7 1/4… should be able to do like 1.5 seconds faster than that, i’d say… but i do realize its b/c it has street tires on it… ---

Ford chose to redesign their engine lineup. There are lots of ways to make power, and all of them are viable solutions. I’m just glad Ford finally put some HP behind the mustang from the factory, I could care less if it is forced or NA. ---

you do realize, Ford does have a 5.4L 3v SOHC engine (2 cams), that puts out 385hp/380tq. It’s rumored to go into the 2006 Mach 1 ---

Anyone will know, that a supercharger does not add to the total displacement of the engine.
