I am new to the Chevy family but I should have joined YEARS AGO after buying my new 6.2 LTZ Silverado. I am looking to do some basic mods and this seems to be the place to get some ideas! So far I think I have decided on a Vararam kit (if they get back with me to tell me it will fit the 6.2), an exhaust system of some sort, tune... IDK! I need some good modification ideas worth the money. Anyone done anything with their 6.2???

 

All depends on your pocket book man! Intake, long tube headers, muffler and tune will put you off to a good start. After that you can go as wild as your money will allow, really. And also what you want out of it; if you just want a hot rod, then put lower gears in the back and a higher stall, every time you hit the gas you'll grin ear to ear.

 

^ what he said, or you can drive to LA and we can fight for your truck lol, Im wanting one badd

 

I was thinking about the intake but was curious about what brands and more importantly what is made for the 6.2 but I really liked the Vararam. The long tubes, possibly the Dynatech. The exhast I'm up in the air about and who makes a good tune? I read somewhere on here about getting the throttle body ported and polished but didn't know if that would be for the money. My gears are stock 3.42's and I wouldn't mind to keep them for the highway mileage. I have never put in a stall but didn't know if that would make the truck very easy to drive on the street. I want to build a Mustang eater and I think with some minor bolt on's, it can be done. After that, possibly a 125 or 150 shot. Idk...

 

First thing that I'd do is get a tune from BlackBear or Wheatley, who are both sponsors here. BlackBear offers a scan cable tune where he sends you a cable that goes from your laptop's USB port to the truck's OBDII port, and you download free software and log your truck while driving. Or you can do some bolt-on's then get it tuned. As for the CAI, I've heard bad things about the quality and fitment of the Vararam...I really like my Volant but it is a little pricey. A lot of guys have modified their stock air box and gotten gains just as good as the aftermarket units.

Don't mess with the throttle body, gains are minimal. Some long tube headers are always a nice addition, and will help in the future as you do deeper mods to the engine, such as cam and heads. Of course an aftermarket cat back exhaust, or even a muffler welded in place of the stocker will work. There is a plethora of cat-backs available...Magnaflow makes a nice unit that won't break the bank, but if you have the dough, Corsa is the best. Long tube headers are a must, don't waste your dough on shorties, unless you're in CA where LT's are not legal.

My favorite mod besides PCM tuning was my camshaft, great gains with the accompanying tuning, even with my small cam. Match a torque converter to the cam's powerband and you'll be good to go. Daily driving a higher stall converter is no big deal if you get a tighter converter and don't go too high on the stall. Check out Circle-D's 278mm reworked TrailBlazer converter for $375. Keep the stall speed around 3k or below and you won't even know that it's there during normal driving.

I know that you're concerned about fuel economy, so I won't mention the 4.10 gears that I was about to recommend

 

LT's are legal in California. But a replacement of cats are not.

There shouldn't be a big difference in intakes between any other block out there from GM. The Throttle body is the same size as a 6.0 so.... that leaves you with more options.

E-fans are not too spendy and yield nice gains and save some MPG's.

I'd say exhaust,fans,intake and tune should be healthy start.

he already has efans but sounds good though, exhaust, tune and CAI will make that 6.2 scream...

 

the vararam fitment is fine in my opinion but ofcourse volant's quality is much better.. , so cai , tune , Lt's for a start then maybe a cam + stall , or go FI, turbo or a supercharger its a joy listening to that whine

 

Thank you for all the input! I will definately be looking into the stall and the Volant. What about the Corvette Servo I hear people using. Any luck with that? Just wondering... BTW, how do you get ahold of Wheatly. His website seems to be down. Thanks again and this forum is GREAT!

 

u could send him a pm on the forum heres his profile

u have the 6L80 i dont think the vetter servo fits.. i always find them installed on the 4 speed trannies never for the 6 speed.. it increases shifting pressure..
