Engine specs on a 2001 360 R/T

Where can I find them? There is a 2001 dakota RT in the yard by me and I'm curious if it's worth grabbing for a swap. I picked up another 67 Valiant that I can modify and I'm looking at reasonable engines for a swap. Can I use the older 904 and converter on it? I already have carbs and TTI headers for an LA. I will be using a 73-6 k frame. I don't know anything about FI so it will be carbed. Can you use an aftermarket fuel pump at the tank or do you have to run stock style? The Dakota is still complete,is there anything else I should grab with the motor? Thanks
