Wow I feel like I do extremely cheap labor now haha. I've done about 4 C6 cam swaps for $400, and about 10+ GM trucks for $350.
@Proud Owner I had that LSR281 231/239 cam you posted earlier with an FTI3600 stall, drove great and sounded amazing too. Only ran it once on street tires 2.0 60ft 11.6 @124
25k miles later it lost oil pressure. Now it's the same 6.2L displacement but w/ forged internals using a BTR Stage IV cam, it drives just about the same just slightly heavier off the line at part throttle.

I would gladly pay someone that did a good job $400 for a cam swap, that's for sure
(though I'm thinking about the job on a supercharged car which has a little more stuff to deal with)

I pulled the engine off my C6 not too long ago in the driveway, it took me about 8-10 hours since I don't have the proper tools. This car has been through hell and back haha.

Now that looks fun. I rebuilt a newer model BMW V8 engine a few years back in similar conditions.. was not much fun. Those engines are nuts.. the heads are the size of most bottom ends. Cylinders are all aluminum (no sleeves), it had no throttle body and uses a system of varying how far the intake valves open to control "throttle"
Only BMW...

Agreed.. $500 is common. And "tune" is so much more subjective than people realize. It's not like you click the "supercharger" button and it's done..
The vast majority of "tuners" change a few tables in the easiest way possible and send you on your way. There are only a handful of truly excellent tuners out there that do the job like it should be done

I think 3900 got them the 10 second slip. Might have been 3600. I've asked Theofel to step in and report what he used.
Yes you need a transmission tune for the converter. And you can ruin your transmission very easily with the wrong tune. Be sure and use someone well experienced in tuning the A6 transmission for your work.

Oh GOD please. I do feel the transmission searching for gears occasionally. Tuner told me it is because I requested for hard shifts. My tune is locked so no adjustments can be made without my tuner at moment unlocking it. I hate that these tuners lock everybody out. Hell, it is my car. I wonder how I can just pull the tune to look at it??
Yes, I managed 10.8's with just boltons and a 3600 Yank in really good air. Now with a 4000 Yank I still run 10's in as high as 1600' DA.
Other mods are LG Streets headers, ported IM, Vararam, Hoosier DR's on 17x9.5 A-molds, GTO spares with M&H bias skinnies. I've been using and tweaking a local tuner's tune myself for the last 6 years after a bad experience with one from a traveling tuner. Hard shifts might make your butt feel like you have power, but they don't get you there quicker.
I'm in my 70's, but still active and doing my own work. I've swapped converters 3 times on jackstands in the garage. It's not that tough.
The car's a comfortable F55 DD with 129K on the clock. It's been all over the country with several road trips of 6K-8K miles. I have no interest in a cam as long as it's a DD.

You have to get a converter if youre going to run any kind of cam really unless its really tiny. Even then youll still benefit from one
Get a real tuner not "some guy" who says he can ya gets what ya pay for. Take your time do your research then shoot. You dont need huge cams to go 11s

Oh the old must have a convertor debate lives on.......... :frown:
I'm running the Comp Cams 227/243 .611/.624 113+2 on my stock stall. At 9* overlap........Life's Good.........you guys can keep your drivability, I like the muscle car feel.

This is my 1st auto trans in my life with a sports car. Members here are stating a nice Torque Converter will pull .5 of a second off of your 1/4 mile time. I have seen others say it will not help at all. ???

^^^Whomever told you a high stall converter will not make your car faster in the ¼ mile is likely also going to tell you the earth is flat.
They are flat out wrong. It's more than .5 - a 3900 stall will get you in the 10's with headers and a tune and a bit of lightening. Tried and true.

a loose stall will ET quicker.........and a paddle shift auto makes for some very spirited driving. Easier to go fast without the extra effort from the clutch and gear shifting. There's a reason the top sports cars in racing use it (Lemans, IMSA, Rolex, etc.,....).

I'm an old dinosaur that still relishes executing a nearly perfect launch and three shifts at precisely the right time to complete a near perfect pass - or even execute a well timed heel and toe downshift heading into a turn.
But I've acknowledged that I will lose most races to a well sorted out automatic. That's ok. I've tried to hone my personal skills over the years and that is a ton of fun.
