or
ST3500
or
SS3600
Minimal fair weather driver... 35%
Drag car & to & from the track 65%

I had the ST3500 with 3.73s. It is an awesome converter, if you plan on running DRs or ET Streets. The SY3500 would be better if you are not planning to run at least DRs :cheers:
Just thought 3:42's would offer the best street/strip tight combo package..

The Best of Corvette for Corvette Enthusiasts





Driving TO & FROM the track.....
I thought about 3:73's, but I think for my driving style & mods, 3:42's with a higher stall converter will really wake my car up.
Still can't decipher which one to get...They all seem so similar to me.
Check out the link on T Byrne's page which copied it from Yank, and tell me of the 3 choices, SY3500, ST3500 or SS3600 which is more preferable. On the left click Transmission & then scroll down to the TC selection & descriptions...

I am leaning to the old reliable SY3500, but the SS3600 looks VERY appealing.
I think with the ST3500 I may spin, and don't really want to break down & buy ET Streets & front skinnies. Would like to stay running the dr's.

Indy, The ST3500 and the SS3600 are nearly identical both are hard hitting converters that require DRs to hook. The SY3500 is more of a street converter that has a low 1.61 STR so it won't hit the tires as hard so you can launch on street tires. The ST3500 and the SS3600 will feel tighter than the SY3500 because they both have high 2.5 STRs, these converters will feel tighter with 3.42 gears than the SY3500. The ST & the SS will give better 60 ft times than the SY3500 assuming good traction

the SY3500 is a nice converter but it does not hit as hard as I would like off the line. I would not be surprised to see you back in 6-9 months.

One thing a lot of guys overlook about a TC is the "shift recovery" (you know the rpm your motor drops to after the shift). This is a very important item. With a stock cam and SY-ST3500 SS3600, your shift recovery will be a little high like 4800-5000, well past peak torque in your stock motored LS1. If you have an upgraded cam or H/C car this will work fine as you will raise the power band in the RPMs. These aformentioned TCs will work for you, but they may not be optimum for your combination. With a ST3200 (customed for my car by Yank) the recovery will be 45-4600, which is just above peak torque in a stock H/C LS1- 43-4400. Another words you will recover in the "sweet spot" and your car will keep pulling hard. With the others the car could flatten out,= less ET and MPH
I know a lot of people think my car is a 'Freak', but some well thought out choices of mods do help. How many other Stock Motored, bolton A/4 cars do you see running 114.75 mph with an 1800 DA, like last Saturday at the ESC CC. Sometimes little details can make a big difference. The choice is yours my good bud El, you can go down the maybe-might be the right road, or the one that has already been paved. Good Luck in your choice.
Mike :)
I'm swapping my SY3500 for a SS3800 (whenever my tranny decides it's had enough.) 3.73s are nearly perfect.





MikieC, IF I go this route, I'll probably be going with the FLPLevel IV tranny as well with the built in shift kit, so would shift recovery be such an issue as you state?
I'm a little leary again of spinning at the line, and REALLY want to stick with the dr's, so my thought is NOT to get something that hits killer hard at the line.
My Yank 3000 is a 2.0 STR, and I leave at roughly 1600-1800 rpms, but even when I leave at 2200-2500, it really doesn't do anything for me except spin & raise my 60' times..
Mikie's point about shift extension gets to the heart of the issue that your converter selection is pretty tightly couple to your engine's power curve (that being mostly a function of cam.) You're not really changing that when you go with the FLP so his caution is still valid. The typical rule of thumb is to upshift just beyond the power peak and fall back to right around the torque peak. It gets a little murky when you start considering converter efficiency and trades you can make on the bottom end. :crazy:
The easy way to do it of course is to find somebody with identical goals and copy what they did. :D


You might want to spend some time on the phone with him too.
I have the ST 3500 with 4.10 and had it with the 3.45 but with the came though with the 315 BFG. However, some of it was when I was playing with the rocks so I can't really give you any baseline data on which way was best.
Mikie might be the best one to model after if you don't plan on going without opening the engine.
Also Arite might be another guy to tap for info on his combo
