Quote: Same heads, same cam, same intake, same exhaust, the 318 will make the same HP as the 360, just at a higher RPM.
In other words, more head, more cam, and the 360 will blow away the 318.
My 5.9 had eddy heads, is making around 400 crank HP. and still gets 16 mpg overall... With a heavy foot.
Sounds good. Its still hard to get excited about putting a 318 in a mean looking muscle car, but as long as it outpowers my old A66 70 340 i'll be happy, and i cant see it not doing that.
Quote: The mustang 4.6 has much better heads than the 318 or 360, thus why it makes more power and gets better mileage than any 5.2 or 5.9 with stock heads.
Yup... better everything, plus the fuel injection and computer that lets me lug a 7000RPM screamer around at 2000 RPM (if need be) and still get wicked MPG. The best part is the 425lb weight and direct 5/6-speed bolt-up... but i digress...
