Re: Question about a 5.3 LM7 in a crew cab dually?
Think of it this way - a stock 5.3L has more power than anything that could ever came factory in your truck - even the 454.

The 454 in my old '79 was such a pig. I think that year was only 205? horsepower. The 242 inline 6 in my Jeep can beat that.

A 5.3 with no emissions and a tune will work great for cruisin and haulin light loads. They are awesome engines and you just cant beat them with a stick. I say go for it!
