Ly6 an 4l80e going in my 65

[jrusher]

Hey guys
I just picked up a 2008 ly6 and a 4l80e that was out of a Savana van and I’m going to swap it in my 65 c10 short bed . Have a few questions. My truck is pretty low 2.5” drop spindle an -2” spring in front and bags in rear .
I’d like to know what engine mounts/tranny cross member work the best for these trucks ? Also oil pan ? I’ve done some searching and looks like the gm performance muscle car pan should do the trick. Also headers haven’t found much info on what guys are using that’s not crazy money ?
Trying to keep a low budget on this build but I know how things add up in a hurry . I’m going to tear this thing down an hopefully only do a light hone an rings and a better cam and springs , car intake/injectors an seal it back up .
Thanks in advance for any help . These ls are all new to me lots to learn
