    I decided to do some digging on actual Boss numbers. In the June 1999 issue of Mustang and Fords, they tested and tuned a '70 Boss 302. The baseline they established was 178.7 hp @ 4700 and 208.5 lb-ft. After rebuilding the distributor and carb (187.7hp), changing the #83 jets to #81 (201.1hp), changed the #81 jets to #79 (206.5), and new plugs, the most they could wring out of it was 210.5 hp @ 6100 and 216.4 lb-ft @ 4100.
    These are rear wheel numbers, on an original FoMoCo assembled engine. That said, M&F noted that the timing chain could use a replacement and the rings must have been a little tired due to the blowby seen on the runs. Since the peak numbers occured at 6100, and that's as far as the run went, it's likely that this engine wasn't done yet, but who wants to trash a numbers matching Boss?

    Here is the complete chart on the Boss in full tune:
    2500 - 95.8hp, 201.2 lb-ft
    3000 - 111.4hp, 195.0 lb-ft
    3500 - 137.3hp, 206.1 lb-ft
    4000 - 163.1hp, 214.2 lb-ft
    4500 - 179.1hp, 209.9 lb-ft
    5000 - 192.7hp, 202.4 lb-ft
    5500 - 206.5hp, 197.2 lb-ft
    6000 - 204.9hp, 179.3 lb-ft

    Notice the flat torque curve between 2500 and 5500rpm.

    As for the '93 Cobra, I didn't dig up any numbers on it except for the factory ratings: 235hp @ 4600 and 300 lb-ft @ 3200.

    The Cobra clearly has the peak torque advantage, but it's average is probably only slightly better than the Bosses between 2500-5500. On horsepower, the Cobra appears to have an advantage, but I an unsure of where these numbers were taken (flywheel, tranny output shaft, or rear wheels).

    Someone dig up a stock '93 Cobra dyno run and maybe then we can make a true prediction as to what would happen on a drag strip with a Stock vs Stock (except for tires) setup.

      Since the Cobra is flywheel horsepower, the Boss clearly is making more power. Real world strip times in equal weight cars with comparable transmissions, etc. the Boss will get there first.

        I am going with the GT40P heads, an HO cam, 1.7 RRs, and probably a Typhoon or equiv intake.

        It will be a good cost effective setup, and looks like I will smoke all you turkeys :evil:

              How about linking to a specific thread to back up your silly claim.......

              Assuming that is correct, a tired Boss motor making 210RWHP shows that a good healthy motor on a good tune should be able to beat your 220-230 at the wheels of the 1993 Cobra.
              Even if your claim would be correct that from the factory as you picked the car up from the dealer that a 1993 Cobra will edge out a Boss 302 on a chassis dyno, it wouldn't take much for a Boss 302 to bury a 1993 Cobra motor.
              I have an article where they took a 450HP rated LS6 motor and put it on a dyno. A pair of headers and a minor tune later it made over the 450HP it was rated at. It could not do it thru factory exhaust manifolds.
              IF you took a 93 Cobra motor and a 1970 Boss 302 motor and would only be allowed to change exhaust and do what would be considered a tuning change for each motor without changing any other major intake or fuel delivery components, there is no doubt who would come out on top (dominate). If you could change the camshaft in each motor with no restrictions on profile, the Cobra motor would go crying home to its Mommy.

                I'm done with this never-ending thread. Try asking the same Boss 302 Vs. 5.0L Cobra question on www.corral.net . Good luck!!!

                  I will let you know how it goes....
                  Due to zero coverage in the Ford rags on the newstand, few of those frequenting the 5.0 boards really know what a Boss 302 is all about. Few have ever even seen one with their own eyes. Since Ford made the 5.0 powered Mustang Cobras the most powerful 5.0 Mustang, there will be those who blindly defend them. I have met and have raced with some of the founders of the corral. You don't have to include the full URL in every post that you mention it in.
