3-4 tenths is probably a doable gain from a 2.73-3.73 swap with a stock converter, all else being equal and traction being fully present. But that's only about half the gains you'd see from an optimized stall speed with stock gears - and then further gains from the 3.73s are limited to about 1-2 tenths at that point. Since your stall speed is upgraded but not optimized, your gains should fall somewhere in-between if nothing else (including weather and traction) has changed.

My battle will now be traction. Id be crazy happy with 12.1. Heck 12.4 or under id be smiling all night. Knowing my luck itll do a 12.9x. Or 13.01. Lol.
Think the one thing i want to get done before a trip to the track is a lt1 radiator.
Need to figure out tires for sure.

Some what, theres been a lot of angry moments but overall not to bad. Take a break and keep on going as far as the build goes.
The absolute worst was since I wanted to reuse the front coil springs. Water had collected in the strut mount and rusted the nut to FUBAR standards. I just remember feeling like I was going to die while having a spring compressor on the coil spring and taking a big hammer or hatchet to that thing, waiting for it to explode in my face. But hey, thats fbodys right?

Full bolt on ls1's and tuned will make 340-345ish whp for a4 and 350+whp on m6 cars. That's with ls6 intake. My bone stock internals in my full bolt on and tune (high flow catted y) 02 m6 made on 91 crappy cali gas, 355whp and 371 wtq using my diablo handheld I've had for it since 2004! My 98 ta m6 stock original shortblock with un-ported 243s and 02-04 ls6 cam, old fast 78mm intake( pretty much ls6) full bolt ons, with ory on perfect conservative tune made 386whp/ 378wtq on cali crap gas using hp tuners on my laptop. Since moved back to FL, I haven't cared to retune either. Esp now that I don't have a dynojet at my disposal
Hope these mods and numbers help you.

Also, 2.73 to 3.73 should gain .4 to .5 easily. Esp with dr's and lca's. Add a step up from stock tq conv and you def will hit a .5 sec faster slip!

I agree. Traction will be even more difficult with the gear swap, so proper tires and suspension will be necessary to take full advantage.
Realistic gains from the gears alone might only be about half that much since the stall speed has already been upgraded a bit in this case. Even with a stock TC, I'd estimate slightly lower gains for the swap.

the best is doing 55mph on the highway due to a moron and getting over a lane and giving it some gas without down shifting and youre doing 70 befor you know it. 2.73's dont do that lol. I cant imagine m6 guys with 4.10s, 1st gear must be useless.

No graph. Mail order tune currently. The funny part is I'm on 245 street tires all around, forget which brand. Felt like the trans slipped on a 3/4 shift too that run so I quit after that.

Na, must've been 2/3 shift. Funny how autos are like that. I dunno if it tried to lock up and slipped? I dont get out to the track much or even really drive the thing much so honestly I wasn't paying that much attention.
I guess my next goal is 12.5s though. Tire would probably be a better mod than an intake manifold?

Yea. A dyno tune is probably in my future. Wish the cheapest around here wasn't $550! If there's 3-4 mph left in the tune that would be awesome. I'm still happy to be in the 12s on a 245 street tire and practically a stock stall. A better tune, some sticky tires, and then a real stall will be my next path I assume.
Those time flips on your site may not be cut an dry enough though. The 2.2 60 is why. I probably was around 2.0x or 1.9s because I honestly didnt spin much at all, never had to throttle it or let off. Pisses me off they didnt give me 60' times but heres a car I ran that ran 114, my r/t was slower than his yet my 330 was a tenth quick. His 2.13 60 would put me lower then that.
A lower 60' gives you a lower trap speed from what I'm told. The quicker you get down the track the less time you have to build speed. Not only that but no one has picked up 5mph from a 10hp gain.
I love the cam but I think you were given some misleading info. Those 60' being 2 tenths off makes a difference in trap speed.

From those numbers i would say I cut a 2.0x or better. I left later than the other car and beat him to the 330. Couldve been a 1.9x but I'll stick with 2.0x for comparison sake. That was a 5th or 6th gen 6.2 car. Which on my run last year I did a 2.013. I wish it had my 60', this might be a better comparison for your site. However I swapped from 2.73 to 3.73 gears too, so not accurate either.
Heres the one from last year...
Not trying to start anything but the facts show a slightly different story then 5mph over a gm hotcam, even though our comparisons are not great. I do think his 2.2 60' contributed to the high trap speed. If I get it dyno tuned we will know for sure though lol. I'm not saying true or false, just need better info. 5 mph may be max, 2-3 mph over gm hotcam may be more like it. I'll keep you posted if the time comes.
Btw, not trying to have an arguement or anything. If my thought process is wrong please let me know. I'm all for learning.
