I have an 02 gmc 1500hd I decided I want to hop up quite a bit since the engine is seized im going to use a ls next shp block stock ls3 heads and a 427 rotating assembly with a 217/228 cam on a 116 lsa and 10:5:1 compression what kind of power would that most likely put out?

Since it is going into a truck, are you using it for hauling or as a street machine? intended RPM range would be helpful as well.

not as common means more $$$ thats it....
Our newer work truck witch has the 6.0 with 823 heads is a complete DOG under normal cruising conditions compared to the older 6.0 with 317 heads. The slightest hill requires a downshift to maintain speed, from around 3500rpm up id give it to the newer engine though.
Maybe the 427 would make up for the cruising speed torque with rectangle port heads???
have you thought about just doing a forged piston/rod 6.0 and a turbo?
