    So I'm picking up an 01 Cobra on Monday. I'm trading my GT for it just straight up! The car has 66k miles, it's laser red, and it's a vert owned by a female. It is completely bone stock. The bad part is it has moderate knock along with a tick in the heads I think. It almost sounds like the primary and secondary chains are slapping around on the front cover. But I've heard plenty of rod knocks in my years and it definitely fits the bill. The cars oil is super clean with no metal shavings or anything of the sort. I made sure to check it before and after running it. IT RUNS AND IDLES PERFECTLY. No misfires, no bogging or surging... She just clunks right along. There are ZERO codes in the car and no CEL on the dash at all. Don't these cars have knock sensors? I am going to try my hardest to upload a video of the car running for you guys that have dealt with this before and can tell me what to prepare for.

    How I can prepare and will it work first of all... If I've got a bent rod or spun bearing or anything in the Teksid wrong I have an 04 aluminum Mercury marauder aluminum WAP block. Same as the non forged crank Mach 1s. Will this block have the same compression or close enough to use while I rebuild the Teksid? Im hoping it's just something simple like the guides and tensioners because it does not sound like it's coming from under the car. It has that hollow sound almost like it's hitting the cover. Idk yet. Didn't get to spend much time with the car. But new bottom or not she's coming home with me and I WILL fix it. I just wanted to get some opinions on what to be ready for.
    I want a cobra. An 01 cobra and I'll do what I have to, to make this work. Stand by for video and pics.

    BETTER VIDEO! Sorry for the camera panning all over but i was trying to use the microphone to listen for the culprit... When it idles down and the camera sits still it sounds like chains...

    It's kind of hard to tell with video. I would get it on a lift and break out the stethoscope. Still a good trade IMO.

    Yea. My plan is to throw the entire marauder bottom end and front cover if it needs it for the WAP block. Just as a temp fix. Then I'll have something that already has a forged crank to build into a PD twin screw boost loving MONSTER! I CANNOT WAIITTT. Never thought I'd own a cobra this soon.

    i also have the marauder lower intake which I hear is wayyyyy better than the Cobras. I'm gonna cut her open and port the bells out and weld her back up.

    i want to see what kind of numbers I can put down in NA form.

    I thought the lowers were the same?? The only difference as far as I know is the upper. The marauder has the throttle body on the other side.

    99% sure ^

    Unless new findings have been revealed, prett sure the lowers are the same or really really close.

    What hp are you to achieve?

    Was reading about the 99 "fix" lowers on SVTP and they talk about the 01s and then the 03-04 Mercs and Mach 1s. As far as I know the 03-04 outflows the 01s lower by quite a bit. It's in the new edge how to section on SVTP. I'll try to find the link. I'm gonna cut her open and widen the bells anyway. Not gonna risk cutting my factory cobra lower so that's a plus either way.. I hear that's where it's at.

    Id like to hit 350 NA so I can hang with most stuff on the road. Then once the teksid is ready with new Rods/Pistons bearings and my nine thread 04 heads for a twin screw I'll spray 100hp of N2O through that marauder block and 4 thread heads. Until I'm bored. 350 should be easy if I start w long tubes.
