Looking at a 05 RCSB V6 red w/t silverado. I know the 4.8 to 5.3 is simple and cheap but Im wondering how much more expensive the V6 to V8 swap will be. I already have the 5.3. The truck is only 6K and in brand new condition with 184K miles on it. Would it be worth it??

 

I spent around 1500 once it was all said and done. That was 4.8 and new clutch, belts, hoses, fluids ect. I did the a/c later at my work.

ive always been wonder what a 6 to 8 swap takes, 8 to bigger 8 is wayyyy easy, but what all do these 6 to 8 guys have to do?

 

you could do like this guy did

In this case it will take, V8, harness computer, engine to frame mounts, a/c lines and accumultor, throttle cables....if your truck is a 5 speed, you will need a clutch, otherwise a flywheel.

Done...and if you do more mods to the motor then just a tune.

this ones an auto. Does the bell housing work the same?

 

Yeah. Your fine.

If you really wanna go for it make sure you buy everything, and then some. I seen a few 6-8 swaps online, and it looks pretty involved for something that just bolts in. I probily could get in done in a week with just me messing around by myself.

 

well I want this to be an imposter SS when its all said and done. But Im hoping to get away with just putting the motor in and letting a buddy of mine do all the electronics. Im just trying to get a list made up

 

The electronics are bolt in too.

GMC did good by keeping truck, and engine electrical sperated. Just lay stuff out before you start plugging it all in.
