I'm looking for the best quality rebuild kit for the 5.3L in my 2001 GMC Sierra 1500. I'm not currently looking for horsepower upgrades but any upgrades related to gas mileage and/or stock performance I am also interested in.

Basically I'm looking for the best quality complete engine rebuild, and if there are any additional upgrades that should have been done from the factory I'm looking for those too.

Thanks in advance, this is a whole new world for me.

When I needed some Cometics to change the CR of my 408, Mike was the only store that had them in stock and he was $40/gasket cheaper than anyone else who would be shipping them 7-10 days from Cometic to me

He will continue to get my business. Good guy, communicative, fast and affordable

I used them for my Tahoe, 50k mi and still runs like a champ. Get flat tops and stage two cam, tune. It makes you wonder why they didn't make em this way in the first place. Make sure you get the book.
