6l80 are junk... Plain and simple... 60 or 80 will be light years more reliable. We have completed NUMEROUS 60/80 swaps. Give us a call if you are interested in having one done.

Using "fast list" is like picking outliers to support your data. I think it is beyond silly. I'm tired of hearing how stock z06s run 10s, yet every time I goto a track they are running high 11s/12s. People need to get out to the track and worry about what they run, and not use internet times from MIR on a perfect day on a perfect launch.

For 600rwhp, I would just do a blown ls3/6l80. If you want more than that, then look at doing a swap to the 4L60/80. I wouldn't start with an ls2 vette unless cost was a concern, and 06+ are 6l80 anyways so only way to avoid that is 05 which is a junk year.

6L80 are not junk. You just have to know how to tune them for each car and specific mods. If you don't want to take the time to properly tune them they will burn up. There are plenty of people running built 6L80's in the 10's and 9's. Just because you don't want to take the time to tune it doesn't mean it's junk. That's like saying that fully built motor blew and it's junk, oh wait I didn't take the time to properly tune it.

Anyways, for what the OP is looking for the 6L80 will serve him perfect for many many reliable years. No where did he say he wanted a full blown 1200rwhp car that he wants to spend
15-18k on a trans swap alone to drive once a month and drag race.

To the OP, with whatever you decide I hope you get what YOU want and within your budget and performance mods needs.

what is so superior in the interior the chrome radio *****? my C6 is a built street car 1SB fully loaded, capable to drive coast to coast and run those times, it steers great, just how much faster or better feeling can a steering change beI could see it in a 20 year change or generation, of course the LS3 is a very good motor and newer is always better depending on what you want to spend, If you took the time to read the fast list you would see I was running in the 10s with just bolt/ons for over 8 years, and really haven't tried for the last 3 years waiting for the Ls3 to catch up, and if you read you will see the same day same tack built by the same shop LS3 H&C sets new record of 10.63, and My LS2 with bolt ons sets new bolt/on record of 10.62,

I did the 6l80 to 4l65 swap. I felt like the 6l80 was faster, but I can't prove it. The only reason I went 4l65 is because I was going to go 800+ whp in the near future.

The key word being BUILT

Have you had a chance to try your car with the new 15" setup ? any time slips, what kinda mph must really be high

Unreal

Nope, don't have the cage/chute/fire/etc to run it here, and closest track that would let me run is 500+ miles away. Focusing on 1/2 mile events. Got 2 coming up.

dennis50nj

I'm not familiar with the 1/2 mile, is that a side by side event,
is it timed and with splits, whats your expected mph

Unreal

Yes, side by side, trap speed only, no splits or anything else. Just going for MPH at end of 1/2 mile. ~170-180? No idea really.

dennis50nj

Interesting, do you go wide open from starting line dead stop, I have no Idea about the gains from 1/4 to 1/2 or the mph gain on the backhalf, like 1/8 to 1/4 is usually 30mph on the back half so the back half is a 1/4 on the half, any idea

Streetk14

At the events I run at, we usually do a 50 MPH roll. Some guys run at a different start speed or go from a dig to try to go for a higher trap speed. It's all for fun, really. It's a little less than a 1/2 mile from cone to cone at the airstrip we use in CA, so it's not something that's set like a 1/4 mile track. It's a hell of a lot of fun though, and really shows which car is faster vs. drag racing where you get to see which driver is faster in most cases.

Here's a run from one of the events I ran at last year with my old car. Was running about 165 mph at this event:

Oops... double post.

But yeah, I do think there are enough improvements to warrant paying a few bucks more for an LS3 car. The steering improvements being one. I like to take turns in my cars, so it's something I value. Don't believe me, read what C&D thought about it: http://www.caranddriver.com/reviews/...ette-road-test

For the interior stuff, don't even get me started on the Pillsbury Doughboy steering wheel or horrid gray interior trim pieces. There's also the unsightly OnStar antenna, the differential that needs to be replaced to handle any kind of power, no NPP option, and that stupid "shift to reverse" thing on 6MT cars. And since I mentioned manual transmissions, the TR6060 is a much nicer shifting trans in my experience. Lots of little things that just make for a nicer car.

dennis50nj

yes i like the doughboy wheel, and the xm antenna its very easy to tell its an 05 and it must cut threw the air faster, as the 05's seem to be faster the rear internals are the same, the gears in the trans are different but not on the automatic, and of course the LMB paint the silver trim can be changed and the wheel, that's just all cosmetic and preference of your own taste and doesn't designate junk

Streetk14

Nope.... not junk. But if starting from scratch C6 shopping, it wouldn't be my first choice. Every thing that you want or need to change = $$$.

Just looking at KBB values for similarly optioned cars with the same mileage, the price difference isn't much between an '05 and an '08. $25-26k for the 2005 vs. $28-29k for the 2008. Once you do the diff upgrade in the '05, it's likely a wash. I'd rather have all the extras that go with the '08.

You can disagree if you'd like.... I'm just being rational about it as a guy who owns neither an '05 or an '08.

dennis50nj

that's true, the 05 holds a higher value because JD Powers gave them a higher rating on a lease buyback or smart buy, either year is a remarkable car in my opinion, and very few mods make it any type of a racing car

Streetk14

Residual values were sky high for some desirable cars before the recession hit. I scored some pretty incredible lease deals during that time for that very reason -- the cars were being over-valued in many cases. And residual value is a huge factor when it comes to calculating a lease payment.

Something like a later C6 or BMW 3-series still holds it's value very well, but it isn't like it was when things were better in our country. Unfortunately....
