Default LS7 2002 1500HD engine build

I'm sort of just doing this for fun and I'm not USINGall converter I'm going to use a dart block and some afr 245s on a 427ci CATHEDRAL port engine with a 224/229 cam on a 111 lsa and 10:5:1 compression maybe drop some 4.56 gears and truetracs in it but either way this thing should make some serious pulling power wouldn't you think

Dart block and cathedral heads: so what's LS7 about it? Rotating assembly?

it will make tons of power, but probably will make stock LS7 power. So if the motor is assembled and runs, "fix" the heads and put it in as is. Need a 58x box if using the OE crank and wheel
