Quote: With all this bashing and negativety about a product I'd thought I would post a possitive report. A customer in Texas has an XR1 block, W-7 heads by Visner with turbocahrging. 1300 at the rear wheels. The math works out to something like 1500+ at the crank. Pretty good amount of power handled by a block everyone seems to like to throw under the bus. The point being these are good blocks.
