I just finished up putting a vortec 454 in Big Bertha. It went pretty smooth. I droped the vortec 350 out the bottom of the truck and slid the 454 in. I only had to change the plug for the injectors. Every other wire just plugged in. I had the computer reprogrammed and it fired right up....Wow what a difference 104 cubic inches make. I can't wait to get the camper out of storage and see how it does.
