i have a 350 bored 60 over with edelbrock intake. pop up pistons. a roller cam dont know the specs of it though and a 600cfm edledbrock carb. Like in my last post i burnt my 700r4 and want to try something different with my new th350 trans will a 2000-2300 torque converter really make a difference from stock if not I will be returning this to back to jegs. Thanks guys for your info im gaining more knowledge from you guys. Heres my car so you can hear the cam not rather sure if its aggresive, mild, or small. It chops so i doubt its small. http://www.youtube.com/watch?v=T2W5zuuPiY8. Also i have a stock rear end so im not sure about chooseing the right torque converter. But plan on changing rear end in the future. Also i just do street driving nothing serious like racing just like to hit the gas every now and then.

Hi Chuck,
A stock converter stalls somewhere between 1300 & 1600
so your new converter will show a difference, & since your not going racing it will probably be just about right.
Good luck,
Rich
PS When looking for a converter the best thing to do is call a couple of company's & ask what they recommend, you'll need to tell them what the intended use is, (90% street or whatever it is) weight of your vehicle, engine displacement, compression ratio, cam profile (duration at 0.050-inch lift, & lobe separation angle), carburetor or injector size, transmission model year, rear-end gear ratio

Thanks richard that was a anwer I was looking for. I think im try my new converter out

You may be in for a disapointment after making the switch,your 700R4 has a steeper low gear than the Turbo350 which gets you "off the line" quicker.So after you do it you may think to blame the converter swap,well that won't be the problem,it's the difference in gearing.

Ya Chuck ditto on what JeffB said. Those 700's are a pretty good trans if you have everything set up for them already. 1st gear is great and will get you off the line quick and then you also have overdrive for mileage. The 350 will be cheaper, easier to set up, and have more converter options but you loose those 2 advantages with the 700. You will also need a kickdown cable and get a new length driveshaft for the swap.

depending on which tail housing the 350 has.. he may not need to change the driveshaft

when I swapped my short tail 350 for my 700r4, I had to take 6" out of the driveshaft.

you will DEFINATELY feel a difference with that converter.

when I had my 700 rebuilt, I had a 2400 stall converter put in, to match my future plans for the engine. i got lucky and have a very 'tight' converter.. if I'm just cruising.. it feels like a normal stock converter for the most part. but when I punch it I can feel the engine flare out to about 2500, and then feel the converter 'grab' and launch the car a lot harder then it did with the stock stall :>

the only time I really notice the stall is when i'm unwaivering at full steering lock. I notice I have to give it quite a bit of throttle to make it move.


just for comparison's sake.. my buddy has a 700hp 496 with a 3000 stall converter (Street car, so it's a little lower then ideal) but it's a VERY _loose_ converter. the car simply won't move with the revs below 3000 rpm, then when the converter flashes the car will suddenly lurch forward (makes putting it on the trailer interesting)

kc8oye thanks for the info. And Im fine I did my home work I dont have to do anthing to the driveshaft because I have the longtail th350 trans 9in and I chose the th350 because there more parts for it and I got a crossmember for it already really wanted a 400 to tell you the truth but didnt want to buy a crossmember and other things for it to get it in when I have already have everything for the th350

The 84-88 G-body's stock TH2004R Crossmember will work with a TH400 Trans, they share the same rear mount location. If your's is 83 Or older you'll need the frame extensions to use the newer model Crossmember w/400.
