I talked to one of the Mopar engine builders who had an early Callies block and he said it had issues. So hopefully those early issues get resolved before the train leaves the station. It would be great if Callies is able to provide a properly machined block at a decent price. A lot of guys would able to step up to 900-1200 hp engines if they had a good block. The rest of the parts are available to build 1000 hp big blocks, just need a good foundation.
