I'm pretty sure the 2v and 03-04 cobra blocks are different. Don't quote me but I think it has to do with webbing, and more main bolts
Head bolt pattern is the same for the blocks so that it can be transferable - but the cobra block has a 4-bolt main vs the 2 bolt main of the GT - which makes most rate the cobra iron block around 700hp (i think) while ours is around 600hp.nope, they're the same. its just a romeo iron block.

I thought they were identical up until about 2 months ago.

Hmm, news to me.The steel blocks can handle higher than 700 or 600. I've yet to see a steel block crack making anything less than 800RWHP. The 5.0's were pretty obviously cracking at 500RWHP but there are plenty of guys with Romeo and Windsor blocks making 700+RWHP with no issues. There are a few guys out there making 1100 HP through the steel blocks.
Also all Romeo/Window GT steel blocks are 4 bolt main (2 on the top and 2 on the side) just like the 03/04 Cobra blocks. The aluminum Teksid blocks are 6 bolt mains (4 on top and 2 on the side).
Bill
03/04 mach 1/cobras used the 2v blocks.
So the 2v blocks also have 4 bolt mains?
