    What radiaot and fans should I use for my truck I got the motor mounts and tranny crossmember in place got my wiring harness back. I was just wanderin since some of yall have been down this road already. And were could I get my computer reprogrammed? I just need the VATS and egr and rear o2 sensors tuned out. and any thing else I need done to just get it running. Oh yeah any one got a mass air sensor they for a 2000 5.3 need one of them too. thenks and suggestions would be appretiated.

    go to nelson for the tuning stuff, other than that i would prob say a 28 inch radiator would be fine, but thats purely guessing there.

    NelsonPerformance.com for a tune. Any radiator that fits your truck will cool the LSx based engine. Be sure you get good fans if you go electric. I would suggest the Black Magic fans since they pull more air than any other aftermarket ones I could find, come with an adjustable thermostat and seals against the radiator with a soft rubber seal to ensure air flow through the radiator. You can use the factory electric fans off of a Camaro/Firebird on a 28" radiator or 2005 Silverado fans on a 34" radiator. It all depends on how much room you have under the hood to fit a radiator.
