2005 silverado 400 ss

hey guys a quick question i just bought a 05 400 ss from mexico. does anyone have one? if so what kind of upgrades have you done? what kind of exhaust....things like that.does anyone know the specs on hp trq? any info would help. plz help your fellow CHEVY LOVER!

I think the mexican 400ss equals the 4.8L V8, but i I might be wrong.

I've seen a few around my area but have not had a chance to figure them out. A Single Cab with what engine and tranny????

what is the 400 ss? never heard of it.

its 2005 chevy 400ss has a 400 hundred small block 6.0 with 345 hp. i have never seen them here in california but i just got one!ill get some pics and post them it will arrive here on friday power everything an auto 4 spd with ovrdrv dont know the details yet but ill let you know.

THe 6.0 L is 364 cid. So is it a 400 cid or a 364 cid/6.0 L? The LQ9 is the 345hp 6.0 L engine. I did not think they made a 400 cid anymore?????

The motors in mexico are different. There aren't the same ones here in the U.S.

I sure hope you didn't buy that thing site unseen. I've NEVER seen a decent vehicle come outta Mexico.

ok guys my bro picked up the truck for me today and it will be here on friday. its not a 400 block its a 5.3 310hp 440lbs trq! pretty good right pwr everything abs,cruise,disc all aroundand center cosule and some more stuff ill put pics a.s.a.p white with drk gray int.i think 5.3 is a 327 right?2005 the last year made, too bad.i wonder what kind of power i can get out of it with bolt -ons?ideas?it is a 400ss though.let me know what u think,thanks!!

Why is it called a 400ss if it's a 5.3? The 5.3 is 325cid, it has a totally different bore and stroke from the old 327. Are you sure about the torque, I have a 5.3 with 310 hp and it's listed at 335lb-ft?

440lbs = NO WAY . It's just a appearance package. You can get the same amount of power from bolt ons as any other 5.3L equipped truck. Think of it as another appearance package such as the southern comfort or choo choo customs trucks of the day.

According to the GM website, the engine in the 400ss is the 5.3 285hp 335lb-tq. They don't list the 310hp engine as an option.
