Umm I believe that we are talking the new 302 engine which are completely different then the Ford Mod motors..,Regardless what does size have to do with it?? Its weight. (all the mod motors are light) and room in the engine compartment.. Like I said before(which you rightly ignored) lets see who can change the plugs faster? You in an F body with an LS or me in a new Mustang with a 302? Its all all day affair in the F car and a 25 minute job in the 302. About the rpm and heat.... Think about it.. use your brain.. Do you see the Ford v8's all on the side of the road overheating from the excessive heat all the rpm has caused? Of course not. Mine does not run any warmer then your Camaro..
I don't have to go far because I have both engines at the shop. DOHC Ford engine is as large as a Boss 429 big block. Depending on accessories, the DOHC Ford engine is approx 3 inches taller. Length with "Accessories" is close, The biggy in width with the Ford being a whopping "7 inches" wider at the valve covers.
"rpm does not create heat, friction and wear?"you say? Guess it just defies the laws of phyics then? Guess all of those Thermal Dynmics classes I took in college were wrong?
I'll debate you if you have something worthwhile to debate, but judging from the above statement your throwing things out there based on conjecture and not fact.
Since you won't believe me, go ahead and google it yourself. Type in "Rpm versus temperature in a Internal combustion engine". Then, go ahead and find actual dimensions of the LS1 and the Ford DOHC v8s and then you can debate me with actual facts.
Do I have to do it all? You guys are the Ford guys, I'm a former GM Engineer what do I know about Ford engines! You should be showing me the dimensions for the Coyote Engine. I even like the Coyote Engine! Apparently GM will only respond with a Challenge from Ford and the other way around, which we will all benefit from.
As far as giving credit where it is due to Ford: Originally I was hoping along with a lot of my Ford brethern for a Nascar derived OHV motor to take over where the 5.0 left off. Chevy already used Fords Symetrical Head/Intake arrangement and put them on their Nascar engines and then the LS1's.
Another side note for those who don't know: Take and LS1 head and drop in on your Ford 5.0 or 351 block and guess what, the bores and cylinder head bolt holes almost perfectly line up. Much closer than even a gen 1 sbc. The pushrod area is different though but it could be converted, but not worth it since Ford and the after market already have great flowing symetrical heads. Unfortunately, GM also adopted the crappy 4 bolt per cylinder design that Ford had to live with for years!
And to give Ford credit in another area it does have a higher specific output per cubic inch than the GM Engine. I like the Mustang, it's a lighter, more well balanced car than the heavy Camaro or even heavier Challenger. I like a pushrod engine pushing a heavy vehicle though. It is compact, good power/weight and is more affective if you want to put the most cubic inches in a compact package. Unfortunately, you can only do so much with a typical ICE design, whether it be DOHC or OHV.
The mileage on the base V8's isn't much different between them assuming what is listed is accurate. Listed as 15/24 on the Challenger and 17/26 on the Mustang.
The Mustang was a V6. Does the Challenger come in a V6?

I'm pretty meticulous about calculating my mileage, as I drive more than most. My Challenger (09 R/T) gets an average of about 19 in the city. I drive it hard from time to time, but not excessively.
I DO have an MBRP exhaust and CAI. Made a slight difference in MPG, but not much. Was around 18.4 before.
While the Boss 302 is a great deal and I really like them.....there are some big stretches in what is considered "close". It's 2 seconds slower to 100mph than the Z06....not to mention skidpad...braking etc etc.
Again, I love them and I think they match up nicely vs. a stock vette and then people can make a personal choice due to style etc.
Why is it the Chevy guys can never give Ford credit when they come out with something new that everybody agrees is a great product.
Hey now I'm a Chevy guy, I give Ford credit for their 9 inch rear ends and now I give them credit for the new 5.0 liter. if I weren't such a poor bastard I'd sell my Buick T type and go buy me a new 5.0 Mustang.
So i do give them credit. Even though I'm not too partial to how the rear end was redesigned for '10 they sorta fuglied it up IMO with the cut corner tail lamps. But still the package is phenominal.
I met a guy last weekend with a new Boss 302, he said they're only building 6k of them and he had to go to go 1000 miles to buy his, but it's a road race car from factory. It really got my attention.
Of course you know GM and Chrysler won't take this sitting down, soon they'll come up with something more powerful to rival the new 5.0 liter.
