2000 Chevy 3500 454 essential mods?

Hey guys, I am new to this section, as I am typically in the '47-'59 or '67-'72 sections. Anyhow, I am looking at buying a super clean 2000 C3500 dually. It is a factory short bed crew cab dually. It's mechanically stock, with 8,000 miles on rebuilt engine and 4l80e transmission. I won't be towing anything super heavy. Mostly just my '59 or old Land Cruiser on a car hauler, perhaps would look at a 24-25' toy hauler in the future. I would plan on adding an aftermarket transmission cooler. I would like to add a performance exhaust and considering other mild performance mods. What have you guys done that have yielded good results? Tuner? Camshaft swap? Intake or injector work? I'd be up for a couple of grand worth of parts. Just thinking that there may be relatively inexpensive modifications to uncork that big block, that could help performance a bit.

Thanks for any tips,
Nik

I have a T400 body 2000 GMC C2500 with the 6.5L diesel rather than the 6.6L Dirtymax that a T800 would have.

I believe the 2000 Chevy/GMC C3500 with the 454 is a T400 body as well. I can move this thread if you wish.

I was curious about that! I kinda figured that this rig would be lumped with the '88-'98 trucks. I just wasn't entirely sure, so I went with the model year range. I would appreciate move, thank you!

Buddy of mine has an old 2000 flatbed and he tows everything in the world with it on a stock 454 motor setup. No power issues at all. The tranny cooler is the only thing I know he added, other than that he is happy.

Black Bear Performance tune for the Vortec 454, change out the muffler, rest of the exhaust is fine. Plugs/wires/cap/rotor (don't cheap out on these parts). Drive the snot out of it!

I've got a 1999 K2500 Suburban with the 454 I drive daily. It has the snow plow package which *technically* makes it a 1-ton Suburban. I've towed an enclosed trailer on a hot day and never saw the tranny run above 195* with the factory tranny cooler.

Love mine! 2000 K3500 454, completely stock and I haul it all. Everything from 42` enclosed with 2 old schools inside, or like this last weekend when I had 1 pallet of rocks weighing 4600lbs and a 2nd pallet of rocks weighing 3770lbs..... over 8300lbs!

Ive hauled up the Grapevine, Tehachapi, Sierras, etc and not once have I started at the bottom with rpms above 3400 and it not been doing the same MPH on top that it was at the bottom.

Pass Lock bypass is a good thing, Ditch that damn flange in the exhaust, great truck!!

Mine just turned 158k
