1991LX5.0

I saw this over on svtperformance it looks like a new boss 302 block, looks like a decent block. I searched but didnt see it discussed anywhere on the forum. How do you guys think this compares to a Dart?

its been discussed

in the newest 5.0magazine there is a quite a lengthy article, comparing the old block and the new one. according to the article they fixed alot of the flaws that the old block had.

86 5.0L

even the "splitous-inhalfous" flaw?

There is also coverage on it in the new 2007 Ford performance catalog. Btw, they are at the dealers now.
From what I see they seem to be everything that the Dart blocks are but they are about $500-600 less money.
They are cast at the same foundry that the 'Powerstroke' blocks come from and they are a 'high tin' content.
They will also overbore .125.
I'd be inclined to get one over the Dart as Ford is not going to put any junk out there.
I think they were seeing the writing on the walls for the current types of 5.0 blocks they were building........

flaws were something about the oiling the lifters, but now they have improved it. just read the article that would be easier than me trying to explain everything.
