The Pond is a new block, side-oiler, improved design (siamesed cylinders), and aluminum. The 428 probably came out of a truck and is iron. If it's a good one (and I'm sure it is), the 428 is about 100# heavier and $4-5k cheaper. The 428 can handle 600HP+ if you want it to. The Pond block can handle more. I went with the Pond because I thought it would be cool to have a side-oiler. But honestly, for practical purposes, the 428 is just as good.
