Cobra Engine Questions
I have a 1999 cobra that rods went through the block both sides and oil pan. My car has been down for months and its starting to get on my nerves real bad now. Summer is coming up and i dont wanna be driving my 54hp 1969 bug. I am also looking for work at the time so i an just trying to figure out some routes that i can go to put my car back on the road.
Whats the differents between the gt blocks (94-02) and the cobra blocks (94-02)? i know that the 99 has the allu block.
Could i use a Mark VIII Block?
Could i get a gt block and put my heads and intake?
If you guys could help my on these questions or if you know anything else.

RE: Cobra Engine Questions
You're better off going with a 93-98 Teksid aluminum block that came in the Mark VIII and 96-98 Cobras. You can usually find one on ebay pretty cheap. The Teksid block is considerably stronger than the WAP (aka NVH) block that came in your car. According to Sean Hyland, it's also considerably stronger than any of the cast iron blocks. Just get some decent rods and pistons this time so you don't end up back in this same position 6 months from now.

RE: Cobra Engine Questions
putting a GT bottom end in would just be dumb.... ur stock cobra came with a forged crank...
If i was in ur position, i would just do a built bottom end. remember, ur heads WILL have to be machined, because there is a 99% chance they were damaged when u blew up ur engine... that might require new valves, and whatnot as well...

RE: Cobra Engine Questions
in 94-95 the GT's were still the pushrod 5.0(215hp)and the cobra was a pushrod 5.0 with GT 40 Heads and intake manifold(240hp), in 96 ford came out with the modular 4.6 V8 the was Single overhead cam(260hp 16 valve or 2v for short) and also in 96 for the cobras ford used an all forged bottom end with the big Dual Overhead Cams(305hp 32 Valves or 4v). in 1999 Both engines were basically the same but updated, the GT head wereported better(P.I swap is99-04 GT heads) and the cobra had a different ECM and Intake which made it 320hp. basically sums it up lol

RE: Cobra Engine Questions
there is no structural differences between 96-04 iron blocks, their internals/heads make the difference. Early 2v had a 6 bolt crank, and different head bolt pattern made at the romeo plant. Later blocks recieved the 8 bolt crank and more bolts in the heads. Cobras recieved the same block, but with fully forged internals. the Teksid block came in 96-99 cobras (only ~60% of 99 cobras though) and the mark VIII recieved the teksid block but a few minor alterations are needed to transplant it. 2001 cobras recieved a less potent Windsor casting of the block, but while beefier it used inferior casting techniques and is good to 900hp.
Depending on your plans, a built iron shortblock will leave you with all the strength you need.

RE: Cobra Engine Questions
The iron blocks are hands down the strongest. But most poeple never come close to the power limit of the aluminum bocks, so if you can get one for a decent price, go aluminum, it's lighter. Any 96-04 block will work. You just need to build the insides. Use forged everything with ARP hardware and you'll havegood setup. The Mark block is identical to the cobra, just different internals and different intake.
