7.0 in a 2001 truck
I have an LQ4 that is on its last leg about a year too soon. What are the necessary changes to get a 7.0 block to work in my 2001 Chevy 2500? First plan is to get a 7.0 short block and simply move my heads, intake, accessories over to it. I know this isn't the best idea for power but it gets a working engine back into my truck. It would be ideal to also replace the heads with something but right now the budget won't hold. What all do I need to change this engine over? Will the motor mounts work? Will my old oil plan work? What about front accessories, etc? Will the computer work and sensors, etc?

Are you talking about a LS 427 or an old SBC/BBC 427?
If you happen to find an LS7, which is the only LS 427 GM factory made, it is probably worth more than your whole truck, so I would reconsider this.
If you plan on building a 427 using a truck block, it is a relatively easy swap depending on what heads you use. Your stock heads will be fine and so will the intake an electronics if you use a crank with a 24x reluctor. All you would need is tuning.
....or maybe I am misunderstanding what you mean...

Well since you are just starting with a block it should be pretty easy. Just make sure you use a 24x reluctor on whatever crank you use. Also make sure you have the oiling system set up right since the block is machined for a dry sump. Using your stock heads on a LS7 seems like such a shame though Using the LS7 heads would require a different intake.

Shorter stroke forged engines are better for boost. The LS7 is a gen IV motor and your LQ4 is probably a gen III motor, so there are different sensors to deal with. If I were in your shoes, I'd build what you got into a 408 like you mentioned. Probably easier and cheaper for bigger cubes.
