Any Engine Builders?

1. seasoned vs. new (in an apples-to-apples coparison). yes. Most reputable teams 'season' their blocks before putting them in the build-mill.

2. Converted 4 vs. Gen VI 4- depends; are the caps your only criteria? what about the better metalurgy and deck thicknesses of the Gen VI? Oiling strategy, lifter support, fuel pump boss, motor mounts, dizzy hole, etc? Like Myclone said- lotsa belief that the splayed caps go deeper into better meat than the stock 4... but is this with bolts or studs?

3. I love the newer 1pc seals, and have less troubles with them, but they make some real nice wrap-around gasket / seal combos for both the SBC and BBC now.

4. That depends- nitrous hard-hitting 700hp with lots of traction, or a more rod-friendly turbo 700hp? either way, at 500hp (in the big-inch marine world) we say goodbye to 2 bolt mains. Mandatory billet caps after 800hp in all our stuff.
