"bear block"..............does that mean it'll be hybernating all winter?

Here's a link to Southern Automotive's site. They give a good description of what they do in building a 351w. I've got one and it cranks some serious hp (I'm not prone to piles of BS like some). Mine dyno'd at 385 hp with Dart aluminum heads, looks like they're using Edelbrocks now, and claiming 410. If you don't want to spring for the aluminum, the GT40's from Ford would work well, though cost some hp. You may think what they do to the block isn't completely necessary, but if you intend to keep the engine and "play" with it from time to time, it would be a waste of money (false economy) to short cut the quality from the block prep
