And I most certainly agree with Carl, that I never like a poured block over most after market blocks but as we all know, some manufactures do not have the advantage of an approved after market block and are forced to work with what they have and improve it any way that they can.
Hey just my thoughts.

We have refreashened a lot of circle track engines using Bowtie and Dart blocks and so far have not seen any problems with cylinders being out shape during the rebuild, I would think if we had any issues we would see it on a leak down test or blowby out the breathers.

I don't know how pouring a block will make the bottom end stronger as it has nothing to do with the main webbing. Adding splayed caps will strenthen the bottom end!! as it ties the main webbing in with the pan rails.

The poured blocks we have seen where the pour stops show alot of wear as the bottom of cylinders do not come up to temp like the top of the cylinders do.

We sonic test all our blocks be fore any work is done and go from there!!!
