I was explaining this earlier in the thread and was met with disagreeance. Oh well, lol.

A redline on any car is only a guideline to go by. With stock gears, the redline actually is the ideal shift point for the 1st-2nd shift. Almost all dyno graphs I've ever seen on mildly modded N/A Machs show peak power around 6500 w/ stock gears and 6.100 w/ 4.10s so that's what I've gone with and it's given me solid on-paper improvements at the track over going by the redline.

Ahhh, makes sense.

I agree the 96-98 cams make more power (I dropped $ on a set but sold them to jmac because of the high expense of having them installed and degreed). Another point to consider is that in any vehicle product line their needs be a clear gap between trim levels so that there's a justification for the higher price of the higher performing car. Just my 2 cents ofcourse, but I think that is what Ford was thinking. Showroom stock with street tires, our cars are probably an average of 4 tenths off a Cobra's pace in the 1/4 mi. From a straight-line performance muscle car enthusiast's standpoint, if MM&FF went a 12.87 instead of a 12.97 many more people in the market for a higher performance mustang would've questioned the extra 6k for the Cobra.

I've always heard that the 96-98 and 99-01 Cobra cams lacked too much low end, and that due to all of the complaints about this, Ford decided to use cams with a stronger low end and more torque. I would think you could expect to lose some on the low end with the 98 cams and pick it back up over 6k. I'm just not so sure that 98 cams are the way to go. To me it seems like the cams are the main thing that separates the older Cobra and the Machs (excluding gearing). I know technically the heads are different, as well as the intake manifold, but I always thought the cams were the biggie.

Yeah we're kinda gettin into a new bowl of wax. There's coulda-shoulda-wouldas with every single car made really. Imagine how the Cobra owners feel....w/ very little extra cost from the factory Ford could've given that car a different CAI, pulley and tune for an extra 100hp. And we're aching over 15, lol. Tweak this or tweak that, but our n/a motors push our 3465 lb. cars to consistent very low 13s in stock form. I think Ford hit the nail on the head.

Stone- I saw you asked what the stock heads flowed and didnt see anyone answer, the stock heads on our cars flow 230 cfm.

Also I dont feel my car drop off untill right around 6600-6700 rpm I dont know if it is because I have an 85mm mass air so I get more air.

I agree. Its always hard to have your cake and eat it too. When it comes to cars and modding them, it reminds me of the old saying "giveth on one hand and taketh on the other", lol. X-pipes give some top end, but take off the low end, same with this cam or that cam, gears, etc. I'm with you brudda, Ford did a decent job on the Mach. Its definitely a well rounded car.

230cfm im gona assume thats with both valves open?
