I have a 1998 mustang cobra and something is bothering me......well for one it has TWO slung rods, and now I have no chance of overhauling the engine block thats in it now...........secondly the extended warranty JUST ran out...... third I had it in the shop a couple months ago for a humming rear end(extended warranty picked up the tab).............. fourth a month after that I had to get the transmission overhauled(no extended warranty)..........now it might be my driving but I don't think in a total of three months all that should go wrong with a vehicle that ford produces, and definately not a cobra. I don't believe I shoulda have TWO thrown rods with 77, xxx miles on the vehicle. Now I have no extended warranty and pretty much screwed out of my every day driver for a couple months unless there is a recall or somethin on the engine that I didn't hear about, IS THERE???

Now onto a more important question.... if there isn't a recall or something of that sort on my engine I am going to get a 5.4 shortblock assembly out of a navigator , the question, Would my heads and intake manifolds bolt right up or would I have to modify something? If my manifolds would not work could I get the Cobra R upper and lower plenums and would they work? Computer wise.....would my computer work or would I have to get a computer for a Cobra R? Fitment wise would it drop right in my engine bay or modifications??? If I do get the shortblock should I change out the pistons, rods, and crank for forged and not flattop pistons(thats what it comes with)? Again I have a 98 mustang cobra. Thanks for all your help. :rolling:

Sounds like someone has driven the piss out of the Cobra over it's lifetime....are you the original owner?

Good luck on all that you'll be doing...should be a beast when ur done.

Okay, so let me see if I got this right. You "slung" two connecting rods out of your engine? And if so how do you know that you did? Or did someone tell you that you did?

I would get a 5.2 bored/stroked motor! 324ci of DOHC goodness.

Get a Navi Block 5.4 DOHC, The heads will work, the intake will have to be modified

with that luck i think youd be better off with a hyundai accent

Yep sure did sling 2 rods. I was heard the knocking one day and stopped driving it and the next time i cranked it to ask a mechanic I guess the rods finally just cracked through the block, cause the next day I went back to look under it and sure enough there was a big puddle of oil and pieces of the block and the connecting rods just chillin hanging outside the block. So a friend of mine pulled them out and was like man I think you slung a rod or two, joking around and needless to say I laughed and was got kinda mad after that.
No I wasn't the original owner a person had leased the vehicle and I bought it after his lease was up.
Yea you right I should go hyundai accent but where's the speed in a hyundai??
I am more than likely going with the navi shorblock cause I am not too big on boring and stroking......don't get me wrong but yea the navi shortblock is waaaaay cheaper to go with than that setup.
What would I have to do to make the lower plenum work? Computer wise will mine work?? How much power and torque am I looking at with the 5.4 block and my heads and intake....cobra r #'s or what? haha doubt it but I bet its gonna be a lot more than what I have now.
