for my winter project im going to be throwing in a 03/04 cobra block from www.50restro.com w/ all forged internals...it's rating is 900hp for only $2,400...i have not found a better block out there yet for the money!
When they are saying Dart blocks they are talking about the 5.0's. Are you wanting to do a 5.0 swap? The actual 4.6L block will last for quite a good amount of power. If you are talking about a short block then just look for a good name of forged internals and go with them.

imho, no "aftermarket" modular blocks are needed....pretty-much ALL the 4.6 blocks, aluminum or iron are pretty tuff, I've not head of any issues wth them like you had wth the 5.0's splitting
Oh one thing I forgot to mention. With a stock 4.6 crank the block will displace 5.0L hence it's name but you combine it with a stroker crank you get a 5.3L.
96-98 cobra blocks are aluminum teksid blocks, 99-01 cobra blocks are aluminum windsor blocks, 03-04 cobra blocks are the exact same romeo blocks that are in the 96-98 and 01.5+ Gts. The only difference is the cobra blocks are machined for 4 bolt mains and the GTs are only 2 bolt mains. The stock gt block from 96-04 will handle more power then 98% of people will ever build.
So if i just picked up a stock 03 cobra block and put the right parts into it, then there would be nothing to worry about, even with a turbo?
how much power and or boost are you looking to make with the turbo?

i have an 01 gt. Can my block be machined for 4 bolt mains??? can i put a 4v head on the block??
no it cannot and even if it could, the cost would exceed the price of a 4 bolt block...yes you can put DOHC heads on it but you'll need alot more parts to make the conversion, so again you may want to shop for a complete DOHC engine....
