5.3 4l80 71 chevy

[v30crewcab]

I got a 71 c10 longbed, and I am looking to drop a 5.3 4l80 in it. Can you do it without a high hump if you move the motor and trans forward, and if you do that, will the driveshaft fit without shortening? just trying to plan ahead a bit. I have a high hump, but if it will fit without no reason to use it.
I know I'll have to change the slip yoke to a 32 spline.
Also, since its already auto, I assume I can reuse the trans crossmember and just move it? Thanks.

Engine/trans fits no problem on low hump without modification in any position. I had a single piece driveshaft made for my longbed. I used the trans yoke from the doner. I used Hooker Blackheart motor stands and trans crossmember with F body motor mounts.

nice thank you. I need to get rolling on this project I guess.

anyone else use the vapor canister vent on the pass side of the tank for fuel return? any issues? I'm planning on running the in cab fuel tank for stage one of this build.

I guess I'll order up a 72 sending unit for the return.
anyone use evil energy fuel line kit?

i went with evil energy hose but not the fittings. i went through summit and picked exactly what i wanted/needed for the fittings. havent ran the truck yet though, but they do look nice

I like the look of the black hose and fittings. don't want red and blue fittings on the engine.

I just finished my swap a couple weeks ago. I used the evil energy kit. I expected a few leaks just because this was the first time I made my own fuel lines. Primed the pump and didn’t have a single leak. I also used their inline pump and filters. So far so good. Have about 50 miles on it so far.
