Hi all its my first thread on this forum and its a swap

I been reading on for a while and it took me a while to register and but i started my swap and yeah i got pic
My 79 C10 that i bought 3 weeks ago
I got my engine this week
and on the truck lol the tire was scrubbing to fender cuz it wieghts 900lb
I took the 6l80 transmission off and took it to a trans shop to switch it from 4wd to 2wd so i can fit it u can see the transfer case that it came with it and i was surprised to know that the trans was heavier the engine
Now i need to figure out were to get the engine mounts,headers and Trans cross-member.
I keep u guys updated and any help or suggestion will be appreciated cuz i am new to this.
