I believe that the 99-04s have a 302 engine block, but I may be wrong.

cobra and Gt blocks are very close to the same. the only diffence is two bolts in the front cover. from what i have read you can get buy with just using a lot of silcone sealant to keep it fome leaking.

btw the 03 04 cobra has and iron block. and they quit using a 302 in the mustangs and cobras in 95.

Default RE: GT block same as Cobra block...

The 2003 SVT Mustang Cobra’s 4.6-liter, DOHC V-8 is equipped with an Eaton™ supercharger and new aluminum alloy cylinder heads that provide increased flow capabilities. The engine produces 390 horsepower at 6,000 rpm and 390 foot-pounds of torque at 3,500 rpm, compared with the 2001 model’s 320 hp at 6,000 rpm and 317 foot-pounds of torque at 4,750 rpm.

To provide strength necessary for the substantially increased torque output, the new Cobra engine is built on a cast-iron block. This unit contains the carryover forged-steel crankshaft, which is fitted with new Manley forged "H-beam" connecting rods, forged pistons similar to those in the SVT F-150 Lightning, and an aluminum flywheel similar to the 2000 SVT Mustang Cobra R’s.

The engine is mated to a TTC T-56 6-speed manual transmission. Behind that, an aluminum drive shaft with upgraded universal joints connects to the rear axle, which now has a 3.55:1 gear ratio

The above is per: — John Coletti, chief engineer for Ford SVT

And isn't the 03/04 Cobra block a 4-bolt main vs the 2 bolt main of the GT?

Edit: also since the Cobra of 03 and 04 are DOHC the heads are different so the bolt pattern is probably not the same since the head gaskets will be different.
