800 hp? Ha, how many 800 hp cars with a STOCK engine are there to know if that is even true??? Anyway, the max hp for the 03/04 4v is probably 500-600 rwhp. After that, the thing is going to fall apart, and at that level it might even fall apart. The internals in it from Ford are forged, so it's definitely a very strong motor, but not 800 hp strong. As far as the 96-01 are concerned, I really have no idea. I haven't seen too many of them pushing high hp numbers, though I'm sure they are out there.

They are basically the same up untill 2003/2004. The 96-01 4V engines all are basically the same. The 1996 and 1998 4V Cobra made 305 hp and 300 ftlbs of tq. The 1999 4V Cobra made 316 hp and 316 tq and the 2001 made 320 hp and 317 tq. All four had the same compression ratio of 9.9:1.
The max power you can SAFELY pull out of one is probably about 475 hp with a really good tune is my guess.
The 2003/2004 Cobra will handle up to 800+ hp because of the bullet proff engine built by SVT.

So buddy, they can handle plenty over 600

The cobra motors are most definatly stronger being they have 40 crank bolts verses I think 16 on a 2v motor.The worst part of the cobra motor is the rods. In the new MM&FF there is an article on this subject and it states that the weakness is worst when the rods are pulling the pistons back down from the compression stroke,that is when the most pressure is put on them but they say that the motors are alot stronger than anyone claims they are and can handle 500hp easy with a good tune like Jdan said but if its not tuned right things can get ugly very quick.So the answer to your question is yes they can handle more power

You lost me here. The Cobra motors have 8 bolt crank, whereas the GT has a 6 bolt crank.

i wa going to comment on that but you beat me to it. i think he is talking about the main cap bolts, but i don't know. i have never seen an engine with 40 bolt mains, and some of the engines i work on are as big as a full size van.

Yes I am talking about main caps and the 4 valve 281 do have 40 main cap bolts which is why they can be strong with epoxy in the water ports.They have bolts coming in from the sides of the caps kinda like a splayed block.I spoke to john linkawitz(spelling) He said he ran a couple steel block cobra motors and they blew up on the dyno so he switched back to the aluminum block and has to problems at all.I asked why everyone says they are so bad bad and he laughed and said I just let people talk when i hear that and sit back and laugh

let me break it down a little. you have a main cap on each end of the block. that makes two. on an 8 cylinder, we will use an old CAT inline 8 for a demo here.
front main, front of engine
2, between the 1 and 2 cylinders
3, between the 2 and 3 cylinders
4, betwwen the 3 and 4 cylinders
5, between the 4 and 5 cylinders
6, between the 5 and 6 cylinders
7, between the 6 and 7 cylinders
8, between the 7 and 8 cylinders
9, the rear main.
no engine other than an inline 9 can use ten main caps. you got bad info.

The Mach 1 is definitely a 4v motor. And a 03/04 cobra can definitely handle well past 5-600rwhp I have seen quite a few for sale on ebay with anywhere from 500-700ish and they haven't blown up, not to mention people on other forums have that much power as well as Jdan and guess what, his car still runs...
