Chevy engine swap

I have a 2005 Chevy suburban 5.3L engine that I would like to replace with a larger engine. I have to replace/repair but would like to get more power at the same time. Can I put a 6.0L engine in? Will I have to change out tranny, radiator, etc also?

Other option is to get a larger vehicle but I like my suburban!!!

You would be better off on the tahoe or chevy specific forums. I looked at it with my 03 tahoe (didnt need it, i just thought more power would be fun) and i think the only difference between the 5.3 and 6.0 was the throttle body and the rotating assembly.

I did a google search a little bit ago and there is claim that the 6.0 will run well on the 5.3 tune.

Keep the 5.3 and put a supercharger on it.
They are very reliable and make good power in mild form.

If I was going to swap a suburban with towing in mind I'd be looking for an 8.1 to put in it.

Well you can put a Duramax in it as I have actually driven one...

But a more cost effective upgrade would be a 6.2. It is already an option in the SUVs and would be the easiest swap of those mentioned. The 6.2 has substantially improved power and is a dream to drive. The exhaust note is excellent as well.

But if money is no object let’s see the DMax Burban

Read this article and you will want the 383 stroker motor to put in.

That's my choice for my 03 avalanche.

If the burb is not a 2500, then I wouldn’t put too much engine/money in it. You will not appreciably increase its towing capacity. But power and acceleration will be better.
