I have a 01 silverado with the 4.8 in it. I want to do some mod to my truck but is the 4.8 a good starting point or should I try to find a 5.3 or 6.0?

 

you could make the 4.8 pretty fast with a cam/stall and tune. but the 6.0 would be alot better starting point and its not too expancive for the swap. i dont think it would be worth it to swap for a 5.3

 

6.0 imo

 

Go go 6.0

 

If you have the tools and room to do the swap it's well worth it, go for the 6.0!

 

It makes sense in theory to go with a 6.0L, that's what I did. In the end my truck didn't run any faster than a similarly equipped 5.3 truck. Actually my truck ran the exact same times(16.2). I went from a stock 5.3 with bolt-ons to a cammed 6.0L bolt-ons+stall+gears. It felt and sounded faster, but it was pretty slow. My motor was installed and tuned by Nelson Performance, so you can assume it was done right + he suggested the stall and gears to me. If my next truck has a 5.3, I probably wouldn't bother to swap in a 6.0L. That's just my experience.

 

Something isnt right with your setup if you ran the same time.
what cam, stall and gears do you have?

i with from a boosted 5.3 to a boosted 6.0 oh boy was that fun..




Whats your budget, thats the tell tale secret..

 

something isnt right if you didnt notice a diff. at the track.

 

going from a bone stock 4.8 to 6.0, honestly I didn't notice a HUGE difference like people make it out to be. It cruised a lot better on the highway and went up hills better that's for sure. Probably gained about 50rwhp.

 

I say start with the tranny, then rear end. Get the tranny built, install a LSD, then go from there...

I would go for a 6.0. Yeah, probably not a whole lot of difference, stock, but start modding and I'm sure there'll be a notiecable difference.
