I have a 2005 Chevy suburban 5.3L engine that I would like to replace with a larger engine. I have to replace/repair since it blew the 7th cylinder 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? Will that give me more power to tow a 26' TT?

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

Its possible as the 2005 Burb 2500 has a 6.0 liter. Probably need a new ECM and other things, but I think the 6.0 it uses a beefed-up T4L80E transmission in the 2500.
