Which V8 engine are you wanting to install?

 

[lsswaptheworld]

350

I need guidance on what I do with the mounting brackets on the frame do I just move them forward ?

Do they sale a kit for this swap ?

Clean up the K member and look for the V8 bolt holes, they are there, stamped at the factory. All frames will have them no matter what engine option is installed. If the current V6 is a 4.3 the new mount locations will be about 3" further forward on the K member. You can also use the V6 engine brackets if you swap them side for side on the V8. Do this all the time on Astro swaps.

What year C-10 and what generation 350, I ask because of your username.

Most c-10's use engine stands/brackets that bolt to the frame, the engine mounts are not bolted directly to the cross member that sits under the oil pan, Like most chevy cars.

Got the mounts squared away thanks guys

Next question. The truck was a v6 before so the harness will it work with the v8 ?

Anything need to be changed ?

 

[Chad & Karen]

The v8 is about 5" longer than the v6 so you might need to add to the wires for the front dress (a/c compressor, alt)
And maybe any temp senders near the front of the engine.

What is the computer on passenger side of the dash I'm assuming that won't be needed or used on the 350

But I did notice 1 plug goes to the transmission from that ecu.

If truck has the 7004r 4 speed automatic. It is the torque converter lock up clutch.

Ok so what else is needed from that harness

 

[lsswaptheworld]

So what is needed to start this vehicle as far as wiring ?

Also the v6 starter doesn't seem to turn the flex plate. Any ideas ?
