I hear people using S10 converters but all I read about is people using 6-cyl ones. Now my friend has a 4 cyl 1988 S10 will the converter out of this truck work behind a V8 700R4 from the same year? If so what will it typically stall at?

 

It absolutely will not fit in your V8 application. The S-10 converters everybody uses, they call the "L35" converter, because its the ones that were bolted to the L35 (4.3L) engine. this is important because the L35 engine used the same 298mm converter that the V8 engines used. The smaller V6 (2.8L) and the 4 cylinder engines used a 245mm converter. The 245mm converter looks considerably smaller and will not bolt up to your V8 flexplate. Nor will it mount on the input shaft of your transmissions, as the 245mm converter used a different style input shaft.

 

That is what I figured but I keep reading some people saying it works and some saying it doesn't throughout the archives.

 

how do vega ones fit then ?

were there any th350 s-10s ?

and can you tell by looking inside a verter if it is a 4.3L one? what do you look for and how much stall will they give you about ?

 

Vega 350 converters are the same input spline and the same flex plate bolt pattern as V8 ones. That has nothing whatsoever to do with S-10 700-R4 converters.

They also don't win races against anything but stock non-Vega ones. A real converter will beat a Vega one any day, even in a Vega.

 

If the "S-10" converter has the code "DBLF" on it. But that's on a sticker so who knows if it'll still be there.

 

howcome auto repair guys and such always swear by vega ones ? are they stuck in the old days still and completely ignorant? i know of one auto repair guy locally that has a vega verter behind his 455 pontiac and it does launch higher rpm's for sure, another guy around the bock, an old guy, has one in an 80s cutlass also behind a 455 but an olds one

about the s-10 thing im curious if s-10 ever could get th350, i dont think so, but im unsure

 

We found a converter out of a 4.3 S10 today. They are pretty hard to find around here but somehow we came across one. It doesn't say "DBLF" on it though the sticker says something else I forget ...but it fits.

 

When I was looking for a V6 converter to fit my V8 700, the counter guy stuck his head WAAAAAY up his butt and came up with "it won't fit. I don't care what you say. It won't fit." and then would only bring me 2.8L 700-R4 converters. What a ******.


Because at the time, it was a commonly known higher-stall th350 converter, I suppose.

 

Because they are (were) cheap and plentiful, and those were the days when "racing" "automatic transmission" was an oxymoron (you know, "jumbo shrimp", "feminine logic", "masculine sensitivity", military intelligence", etc.). Real racers know better.

We can do much, much better than a sloppy-loose converter that merely allows a nutted 4-cylinder to actually cause a 3100-lb car to move, through 3.08 rear and 2.52 trans gearing. Nowadays we can not only design one that allows the engine to rev higher with the car sitting still, but also hooks up when the car gets moving.... which is the Vega converter problem. They never hook all the way up behind anything with more than 200 ft-lbs of torque.

 

have ATI build you a real converter. you will never have any problems and you can tell them what you want. if your gonna do it right, do it right the first time and save yourself alot of time and aggrivation. my dad's ati has over 900 passes on it and is over 12 years old.
