Early pre-production Arrows had air pockets and inclusions in the castings, haven't seen much more since then. I don't know why it's cheaper to go Chinese when we have so much iron here. We used to be the smart country (apparently), but nowdays nobody can be bothered. They just shut down the foundry for Ford, why not keep it open for contracting small jobs like this? With all that's already invested, it would pay to go with a decent block. Dart has the experience and reputation, and bang-for-buck I think can't be beaten. Available in 4.125 bores for easy cubes, work better with big valve heads. More aftermarket gear available for the bottom end, serpentine conversions are easier with reverse rotation water pumps, general factory accessory mounts, etc. Sent from my CPH1903 using Tapatalk
