Can someone tell me what the hole is in the 324 block? I shot some oil down in it and it drains out at the crank underneath and back into the oil pan. All of the circles are of the same threaded bolt hole, top is the stock 4.6 iron block, bottom two are the 324 stroker block.. is this going...

About to order the Quadrant and Firewall Adjuster, is this all I need to order? I hear the stock cable is a good peice and the best to re-use it, just making sure I am not missing something. Thanks

I am pulling the engine to replace the head to the revised head to get rid of the "Tick". I doubt Ford would warentee it with the KB sitting on top and they would find a reason to void the warentee one way or another if I de-modded it. I figured since I have it out, might as well do some...

Does anyone make a scatter shield for our tranny's? I have not looked that hard underneath.. is the bell housing detachable? I am about to upgrade the clutch and to the 26 spline input shaft and would be nice to add a scatter shield if they make one. Thanks

Is anyone running these? They fit on our stock rims and look ok? How are they vs Nitto's about the same traction, better.. ? How about against the BFG's? Surely someone is running the ET's..

Looking for the JBA shorties, who has the best price?

Which clutch should I go with, have the KB, going with Crower Cams.. are the two best the Centerforce and the twin Mcleod? Going with the 26 spline input shaft as well. Who has the best prices? Sorry, search is down. Thanks

What is the best place to order the official 03 Cobra manual, how much.. I heard about $150 or so. Phone number?? Search is down. Need the engine manual. Thanks!

So can we order the T56 Input shafts now, where can I order one.. best price? Is it an easy unbolt and replace with new input shaft, along with new 26 spline clutch disc?

I have to replace the driver's side head due to the tick, I dont trust any dealer to not take it for a joyride or scratch or damage the Cobra. I want to know it is done right, so I will just do it myself since I have done everything else on it. I have the KB so they probably wont do it under...

Anyone ever bought their own new head and installed it themselves to fix the tick? If I have to pull the KB off and put it back to stock before I take it to the dealer, might as well just do it myself.. I really dont want anyone else working on the Cobra or taking it for a joyride if you know...

Can someone tell me which fuse is the fuel pump fuse on the 03 Cobra? I bought my Cobra used and did not come with the owners manual. Tried doing a search, but no luck.. Thanks

Hey guys, Anyone ever have the electrodes damaged on their TR6 Plugs? Is it possible they are just defective or weak electrode plugs, too hot? I dont want to think, gulp.. detonation. I never heard any at all.. I suspect detonation as the driver side front, the second and last plugs...

Who has the highest HP/TQ out of an 03, KB or not without spray? I guess I should not get wrapped up in in numbers, but since I have gone this far and lots o $. I want to try to get as much out of it as I can to justify in my head the cost of the KB. I am not interested in being on top, just...

I cant seem to get a good tune going for my KB. I am running 23 lbs of boost, no belt slip - fixed.. I only see 513wrhp and 558rwtq with a decent A/F maybe a little lean at the end, Diablo has custom fixed this for my Dyno guy. I have not been back to re-burn and try again yet. I wish I...

Anyone ever have a 100mm idler rub on the Metco lower? The same day I installed them it started making a grinding noise and sure enough after removing each 100mm idler one by one the lower idler on the drivers side was rubbing on the Metco bracket somewhere.. it is in the upper position as...

Question, is the KB "Diablo" Revolution chip that comes with the KB able to be used on the "Diablo" Delta chip? I have both chips and dont have the switch for the Delta chip, which is what I am using now with the KB. It was never sent when I got the Delta chip for my 2.8 Eaton tune as I only...

Just installed 55lb injectors and a new tune for my KB, my wideband says it is rich WOT.. dipping into the low 10's A/F wise and was wondering if I swapped my 6 lb lower for my 8 lb lower to add 2 more lbs of boost how much this would lean it out? I am running 100 octane so that should be fine...

Has anyone installed a Diablo chip and had the traction control light say on? I installed the new KB tune and 55 lb injectors last night and now the traction control light stays on, any thoughts?

I remember reading a couple of posts on various boards mentioning the tendency of 4.6L's to throw rod bearings? Is this true?? Could they be talking about pre 03 Cobra engines or does this apply to 03 Cobra engines as well? I have also heard the location of the wrist pins causing the motor to...

Good gosh, what a nightmare. First I pulled the battery, moved the power steering to get to the alternator and change the alt pulley to a 3.5" for the 6lb lower going in. I hope I never have to replace the alternator is all I can say. I installed the Metco 3.5" pulley on the alt with the...

I am planning the 55 injector upgrade, my question is can I loosen the bolts holding the KB down and lift it enough to remove/install the injectors and then retorque the KB bolts down again and have the gasket seal again? I think I am going to try this since the KB has not been on that long...

Anyone heard of a "P1506 Idle Air Control Overspeed Error" ? I have O/R X so I need the mil eliminator for that.. actually will turn off the back two in my new tune on the way, but have not seen a P1506 code before. I dyno'd my KB last week with lots of belt slippage, actually pretty much...

With a 3 1/4 upper 15lb KB pulley and a 6 lb Metco lower 3.5 alternater pulley, BF aux idler (90mm) what the heck size belt should I run? Any idea's? Thanks
