So the Cobra was acting funny, did a compression test and #1 cylinder had 0! Took the valve cover off and laying there was two exhaust valve springs broken into pieces:dw: Also looks like the valves may be bent as well:fm: I am using the Comp Cams Stage IV cams, and the heads have Ferrea...

I was going down the road a few days ago and all of a sudden the motor lost power and started to idle really rough. It felt like it went from 500hp to 50hp in a split second. Didn't throw any codes at all. I took the plugs out and cyl 1 & 3 were black and wet, plus plug #3 had the prongs bent...

Hey guys, just got the motor back in the cobra:rolling:It won't stay at a idle. It will fire up and then go dead. I can keep it running with a little gas pedal though. and it sounds like it has a little whistle sound near the rear of the motor at high rpm's. So today it threw a P1507 code as my...

Can you put a T-45 in AFTER long tubes are installed??:bored: PLEASE tell me there's a way.....PLEASE!!!!!!!!!!! I put my long tubes on the engine before I put the motor back in the car. With a little luck and pushing and shoving, the motor went in with the long tubes installed. I thought...

I just got a set of BBK long tubes for my 97 Cobra. It only has 2 02 bungs, but the I have four 02 sensors from stock. Do I just use two sensors and tune the other tune out? Also, my H-pipe has a 02 bung welded in it, should I use a third 02 sensor there or weld it shut? Thanks in advance

Where is a good place to get them for long tube headers?

Like listing says. Also need matching x or h pipe. Have cash in hand!

My 97' 4V spun a rod bearing months back, had it all rebuilt with all forged stuff. I was told that I HAD to replace the oil cooler because it may have metal shavings still in it and there is no way to clean it properly. If this is the case, where might I buy a new/better one from. I got $6K...

Are there two keyways on the small cam sprockets (cam to cam)? I found the one on each cam, it's like a 1/4" square plug thing. Or is there the small one and a larger one? My engine builder says there's two, but if there are, I don't remember taking them out. I just remember the little...

Service manual says to put it in front of the #5 main bearing saddle, which would put it closet to the front of the motor. BUT, I have the Sean Hyland rebuild DVD and he says it goes BEHIND the #5 main bearing saddle, which would put it on the outside of the block, closet to the flywheel...

Motor is finally back from the machine shop...Was gonna do N20, but been there done that:dw: So I want a Procharger now:banana: Looking at a P1 or maybe a D1. Heres what I got: 97 Cobra, Teksid block punched +.020, with Probe Flat Tops (no valve reliefs), Probe Billet Ultra lightweight...

Lookin at possibly going with a Procharger or Vortec. But I want to keep my A/C blowing cold on these hot days in Mississippi, but still want to make tons of power. Is this possible?:dw:

Wanting one or the other, prefer D1SC though, polished or not. Must be a 100% bolt on ready to go kit. I don't want to piece together anything. You sell it, I buy it and put it on and go! Would prefer to keep my A/C as well:dw: PM me or send pics and info to: [email protected]

I read bunches of post to remove, not to remove, remove the butterflies and so on for the imrc's. I'm runnin nitrous when I get the motor back, and I just cleaned up the imrc's. Would I be better off puttin them back in "as is" or take the butterflies out?

So I took my forged Cobra crank to the machine shop today after it spun the #7 rod bearing. He is having to take .030:dw: off the crank. Not just the normal .010 clean up. So I ask, am I going to have a problem finding +.030 rod bearings? And by taking .030 thousandths off, is this going to...
