Car Poll

The ONLY choice is to get all 3. This is DFWMUFUCKINMUSTANGS!! Choooo$$$$$

Also something to do with the intake on the 98 cobras being different then 96-97 cars

[LaserSVT]

Negative. The 94-95 is the car to get.

Meh, I am a modular guy. They are just pretty plus the Teksid block is, IMHO, the best block Ford ever made. Its the strongest anyway. The 94-95 block will split the valley when pushed beyond 500hp. I have seen Teksids on the dyno at 1200 rwhp and the blocks take it with no problem.


The 96-98 Cobra has a better block but the 99/01 Cobra has better heads. Better port velocity. They changed again for 03/04 and flowed even better, closer to FR500 heads.
If memory serves I think the 04 Mach heads got the better valve guides the 04 Cobras recieved as well.

Are you fucking trolling?

Because its obvious as hell you have no idea what the fuck you are talking about. Get your dumb ass back to the Garage.

dude, hes correct......reading comprehension isn't your strong suit obviously. The 03/04 cobra motor (which is what they were comparing to the mach motor) has 8.5:1 compression and is a gurless turd without the blower. what did he ssay that was factually incorrect?

There are NO changes in the 96-98 Cobra motors other than what I stated. Same plenum, same B heads and the tune is the same. 98 Cobras have better cup holders and no clock on the dash top. The C head wasnt untill 99. It got slight tweaks for 01 and more tweaks for 03 and even more tweaks for 04. Even though they are all "C" heads they did get better.

The B heads only changed once and that was in late 94 for the Mark VIIIs. They switched to behive springs late in 94 since the 93's would get valve float around 6200 RPM.


Also if you took an early production 96 and a 98 Cobra, stock for stock they make the same peak power but the 96 has more "meat" in the midrange when the IMRCs open around 3200 RPM.

Pretty sure intakes where different on the 98 cars

98 Cobra:





96 Cobra:







I have done several Cobra plenum swaps onto Mark VIIIs and have done 96/97/98 plenums. Had them open to replace the seals and have not seen any change in the runners or anything. Which makes sence because the ECU coding is the same for all three years and if the 98 had changes to the plenum the scholars would be different in the tune.

are you talking about the plastic IMRCs (98) vs the aluminum IMRCs on the 97- cars?

Ah, didnt think about the IMRCs. Guess that IS part of the intake. They didnt flow better but did help keeping heat soak out of the plenum. They are also easier to plug if you wanted to delete the plates. Which you dont wanna do unless you are putting a twin screw on it.

I don't know what fact I have wrong. I'm not trying to be an asshole by stating the fact that a n/a 8.5 compression motor (with some stronger internals) will not produce as much power as the same motor with 10:1 compression ratio. They have the same cylinder heads and cams too.

The mark VIII heads do change ever so slightly in the 97-98 year. Early in production, the valves are shrouded and they aren't in later years. Nothing really worth noting. Also, the beehive springs didn't come in until 96 on the Mark VIII.

you were factually correct. carry on.

[Wish4svts]

Why did he even bring up the 03/04 short blocks anyway though? Those weren't even being discussed.

Edit: I see laser did mention it but don't really know why… This was a thread to choose between 03/04 Mach 1 or 99 – 01 cobra.

What changed in the head? I know the VCs are different due to the COP changeover but wasnt aware the head changed.

As for the Beehive spring, I dont care for first gen Marks so never really retained much info but I am 99% sure they had them in 95. I needed some VCs and there was a 95 base at the pick n pull and it had beehives on it.

Someone suggested the mach because it was "a cobra motor without the blower"
