What do you Guys think a stock 6.0 either lq4 or lq9 with a nelson tune, LT headers,2 magnaflow round mufflers with no cats, auburn lsd + richmond 3.90 gears,and a built 4L60e or 4L80e with a 3K stall, would do on the 1/4 mile?? Im planning on doing that on my '99 chevy RCSB. maybe in oct or nov.

 

low 13's-high 12's i would imagine...

I'd go ahead and get the 4l80e just because, you want to do it right the first time.

Getting tired of the little 4.8 i see, lol

 

I would throw a cam in there too
while its out

 

What would i need to get that 4L80e in there?
Maybe i'll add a cam to that sucker. Im kinda getting tired of just 15.2(lol) all the time i go to the track on the 4.8

 

if you can get it to hook i say high 12's.

 

When you do the swap, peewter, are you going to just tune the stock 4.8 pcm or are you getting the 6.0 pcm to go with your swap? Bc if you get rid of your current pcm, i'll buy it from you... im having some problems with my computer at the moment.

 

Maybe i'll use an 02 pcm, and i'll sell you the old pcm. but if i do that it'll be in oct or nov.

 

A friend of mine has a similar set up. 02rcsb Lq9 LT's no cats cutout, but he has open diff and 3.42's. He runs mid 14's consistantly. With my tune he ran a 15.8, but his trap was 97mph. Serious traction issues. I'd say with 3.90's and traction, solid 13's maybe better.

 

Well i just want to be in the 13's and if im in the 12's thats even better. I just want to play around with some L's and some hemi's!!
but whats needed to to the 80e swap, if someone knows can ya please tell me? thanks LATER!

 

If I ever decide exactly what I'm gonna do with mine you'll see. If I stay with the n/a lq9 with heads and cam I'm gonna shoot for about 12.20's. Anything else, (charger or stroker) i'll be hoping for more like 11.6's. But I'm probably gonna stay n/a. You should not need to go through all the trouble and hp loss of the 80e if your gonna stick with a n/a modded 6.0. You'll be perfectly fine with a built 65.
