Problem is that the 302 and 351W start splitting from in the mains. The cracking works its way up throught the center of the block's mass causing the lifter valley crack.

yea but you end up spending like another $600 just to be able to support ane extra 100 hp. and looks like the lifter girdle requires machine work, so that is more cost added on. Doesnt put you far away from a nicely used race block.

Just for the sole reason that on their website they show a stock block cracked in half and under the caption they say "Picture above was a FORD Motorsport "A4 Block" I think they are snake oil salesmen and their product is a joke. I think the intake puts plenty of clamping force in the lifter valley area and the cracking starts in the main webbing area not the lifter valley. I don't have either on my motor and it's makine 600 at the flywheel. Theres a thread on turbomustangs.com you might have seen it Scott, it was about Tommy's car that's making like 680 rwhp with just the DSS girdle. I guess it's just luck because some block castings are slightly stronger than others, some people split their blocks at 400 rwhp and others make 650 rwhp and it works fine. I'm gonna get the prc halo type main girdle that ties into the oil pan webbing like the one BarryD is using, hopefully I'll be able to make 600-650 rwhp without a failure. Or should I say, I hope I get lucky and have one of those special blocks.

I saw that too. I'd LOVE to see someone do that to an A4 block without the aid of a sawzallIt may have its technical merits, but I don't think the block twists so much as the mains move around. Once the mains move around you'll bind the crank and really break shit.
I've heard stories of people making 1000hp with a good block and a stock crank. The stock crank is strong, but not when its being bound and moved around on its axis.
Basically it boils down to this, if you are making enough HP to question the longetivity of your block, you should buy a better block.
If its a game to you to see how long the stock motor will last (Rubberneck, SOL93) then let it ride and take pictures of the pieces

I really wanted to let it ride and see how much my stocker would take but the opportunity arose to get a R block at a good price and a good builder agreed to take on my project at the same time so I could not pass it up. That and I was not about to build a custom $900 converter for a block that was bound to split sooner or later.
More power (literally ) to you guys pushing the stocker to the upper limits but be careful when you are driving through the mess when it goes boom.
